How can we help?

The 3D Room Scanner turns a real room — or a blank canvas — into a measured 2D floor plan, a matching 3D model and files you can hand over: drawings, CAD files and a quantities sheet. You capture on an Android phone or draw on the web, then refine everything in a browser CAD workspace.

Two ways to start

Scan a room with your phone

Stand in the room and tap its corners, ceiling, doors and windows; the Android app builds the walls, openings and heights from your taps.

Draw it on the web

No room to scan, or no Android device? Press New project in My Scans and draw the plan by hand. Everything downstream works the same.

First steps

1. 1Register free or sign in — the same account works in the app and on the web.
2. 2Capture a room on your phone, or start a blank project on the web.
3. 3Open it from My Scans — scans upload in the background, no cables.
4. 4Refine it with the CAD tools, then export drawings, CAD files or a quantities sheet.

The sidebar on the left

Signed in, you get a navigation rail: My Scans, My Profile, Billing & Plan, Showcase, Overview and this Help Center. Collapse it to icons and it stays collapsed next time; it steps out of the way while a project is open, and it is hidden on small screens.

Projments BIM is the web workspace behind the 3D Room Scanner. The phone captures the room; Projments BIM opens that result as an editable building model in your browser. The measured 2D plan, 3D model, room data, views and schedules all describe the same project rather than separate drawings.

How the Scanner and BIM work together

1. 1Capture one or more rooms in the Android app, or create a blank project on the web.
2. 2The project appears in My Scans when cloud sync is available.
3. 3Open it to enter Projments BIM and check or refine the measured plan.
4. 4Add detail, organise views and schedules, then export the files you need.

What makes it BIM

The workspace understands building elements, not only loose lines. A wall has thickness and height; a door or window belongs to a wall; a room has a name and measured area; levels organise storeys. Editing the model updates the connected 2D and 3D views, and schedules read their values from those same elements.

What you can do in Projments BIM

Draw and edit

Create walls and geometry, then move, copy, trim, offset, rotate, align, constrain and edit exact values.

Build the model

Add rooms, levels, doors, windows, archways, furniture and reusable custom blocks.

Document

Add text, hatching and dimensions; create floor plans, ceiling plans, elevations, sections, 3D views, cameras and drafting sheets.

Review in 3D

Orbit the model, walk through it, control its display and create a snapshot.

Report

Create schedules for rooms, doors, windows, walls, furniture, blocks and levels.

Deliver

Export PNG, PDF, SVG, a print report, DXF 2D, DXF 3D and CSV quantities when the relevant modules are included.

Where it runs

• Projments BIM runs in the web browser; there is no separate desktop installation.
• Open a project from My Scans. The same Projments account is used by the phone and web.
• The sample apartment opens in the real workspace, so you can try the tools without changing saved data.

Projments BIM and your pack

Projments BIM is the module that allows editing in the web workspace. Without it, your scanner projects remain safe and the phone app still works, but opening a project on the web shows a view-only message instead of the editor. Export, Reports, Blocks, Settings and Project sharing are separate modules and can be locked independently. See Plans and modules for the full list.

The Showcase is a real three-bedroom apartment scan: its total floor area, rooms, doors and windows, the 2D plan and a table of measured rooms.

Try it without an account

• Open the full project — the real workspace, fully interactive: draw walls, place furniture, export.
• No sign-up, no install. Nothing is saved; everything resets when you leave.

The sample in your account

On the web

My Scans → Sample project tab. Explore every view; it is read-only and cannot be edited, saved or deleted.

On the phone

Projects → Sample project tab, also read-only.

The Android app captures rooms and keeps your projects on the phone. It uses the same account as the web, so what you scan reaches My Scans in your browser.

Get the app

• It is free on Google Play — use the Get it on Google Play badge on the 3D Room Scanner page. Until the release date, that section shows a countdown.
• It needs Android 8 or later. Scanning also needs ARCore (Google Play Services for AR).
• On first launch a short tour with a demo apartment shows what the app does. Open it again any time from Profile → App tour.

Updating the app

Every new version on Google Play is required. When one is out, the app opens on New version available: Update downloads and installs it right there and the app restarts by itself; Close app closes it, and the message comes back on the next start until you update. If Google Play cannot be reached (offline, for example), the app opens as usual.

Sign in or create an account

One account works for the app and the web. Create a new account asks for your name, email and a password of at least 8 characters. Signing in needs an internet connection; after that, scanning works offline. Explore the demo first on the sign-in screen opens the tour without an account.

Dashboard

• Your active and archived projects, measured models, total floor area and storage used.
• Cloud backup — how many projects are backed up, uploading, changed or failed.
• Needs your attention — failed scans, interrupted scans, failed uploads and unsaved changes; and Pick up where you left off.

Projects on the phone

• Tabs My projects and Sample project; filters Active, Archived, Shared and All.
• Search projects, sort by Last updated, Date created or Name, and group by Building or Client.
• The ⋮ menu: Continue, Export, Open on the web, Rename, Duplicate, Archive, Share…, Upload to cloud, Remove from cloud, Refresh from cloud and Delete.

Create a project on the phone

Only the Project name is required. You can add a client name, building, floor, room name or number, notes and a preferred unit. In the project setup you can also set the brick and tile size used for quantity counts.

App settings

Language

System default, English or العربية (Arabic).

Default unit

mm, cm, m, ft or in, and the number of decimal places.

Default brick and tile

The sizes new projects use for quantity counts.

Haptic feedback

Vibrate on taps while marking.

Theme

There is no theme switch — the app follows your phone’s dark mode.

Other

The Profile tab holds Settings, Restore from cloud, Privacy, Diagnostics, Delete all local data, Help, App tour and Sign out. Support has its own tab in the bottom bar.

You mark the room rather than sweep it: tap the corners, the ceiling and the openings, and the app solves the walls and builds a measured 2D plan with a matching 3D model. The app never draws a wall you did not mark.

Before you start

• Stand where you can see the whole room, with even lighting.
• Allow the camera when asked — the app uploads no camera images.
• Open a project and start a scan. The picture guide opens first; then press Start scan on the Prepare to scan screen.

The picture guide before every scan

Each scan starts with a short guide: one moving picture per step — Stand in the room, Floor: tap each corner, Floor hidden? Pick Ceiling, Tap the gold dot again, Tap the ceiling, Doors & windows and Tap ✓ to finish.

• Next and Back page through it; Let’s go on the last page starts.
• Skip goes straight to the camera and turns the tips off for this scan.
• It opens with every scan, in every project — that is on purpose. Close it by hand each time. To see it again, tap How to scan a room (Watch the quick picture guide) on the Prepare to scan screen.

Tips over the camera

While you scan, a small card at the top shows the picture of your next tap — the floor corners, closing on the gold dot, the ceiling, then doors and windows. Tap the card to replay the whole guide; tap ✕ (Hide tips) to hide it for the rest of this scan. It stays out of the way while Corner points are on, while a point is selected and while you re-anchor saved rooms.

Scan a room

1. 1Floor corners. Turn around the room tapping each corner where the walls meet the floor, one by one. Floor hidden by furniture? Switch the chip to Ceiling and tap that corner up at the ceiling instead — one room can mix both.
2. 2Close the outline. Tap the first (gold) point again, or press Close outline (it appears after three corners). The bar shows Room closed ✓.
3. 3Ceiling. Tap the top of each vertical corner line, where the ceiling meets it, so stepped or sloping ceilings are measured — or press Flat ceiling after the first one. A room traced at the ceiling asks for the floor instead (Tap the bottom of each line, or Flat floor).
4. 4Doors and windows. Choose Opening, tap one corner of the opening, then the opposite corner on the same wall, and choose Door, Window or Open passage.
5. 5Finish. Tap ✓ (Finish scan), name the rooms (e.g. Kitchen) and press View room.

Move or delete a point while scanning

• Tap a corner you placed: it is picked up, and the bar says Tap the new spot. Tap where it should be and it moves there. The bar also has Delete, and ✕ to let go.
• Picked up the wrong one? Tap another corner and that one is picked up instead.
• While a point is picked up, tapping the gold first corner picks it up rather than closing the room — press ✕ or Close outline first.
• After the room is closed, tap a wall to Delete wall or Add corner here.
• Undo last mark (the undo arrow) takes back your last tap.

Corner points

Turn on Corner points (the target button above Pause) and the app looks for room corners where you aim. Each one it finds shows as a violet point, with red lines along the edges that meet there. Tap a violet point to place exactly that corner — it counts like any tap of yours, so closing, moving and Undo work as usual. You can still tap anywhere yourself.

• Nothing is placed until you tap: the app offers points, it never marks or draws walls on its own.
• The Floor / Ceiling chip decides where it looks.
• Hold still — points are only looked for while the phone is steady.
• Point at the floor a moment — it needs to find the floor first.
• Tap one ceiling corner first — for ceiling corners, place one by hand so it knows the height.
• No edges — move closer — nothing in view looks like a corner.
• Corners you have already marked are not offered again.

Freeze the picture and zoom

Freeze the picture (the pause-circle button) holds the camera picture still, inside a violet frame, so you can place points on it calmly. On a frozen picture no points are offered: a tap lands exactly where your finger is (Frozen — tap anywhere). Back to live returns to the camera; pausing, finishing or cancelling also does.

Pinch to zoom in for a precise tap. Zoomed in, drag with one finger to move the picture around — live or frozen. Tap the zoom chip (e.g. 2.0× — tap to reset) to go back to 1×.

Several rooms in one project

Press Next room after finishing one room and trace the floor of the next. Corners snap to walls the rooms share.

Controls while scanning

Floor / Ceiling / Opening

What your next tap marks.

Corner points

Offer violet points on the corners in view, to tap.

Freeze the picture / Back to live

Hold the camera picture still to place points on it, then return.

Flashlight

Light a dark corner. Only shown on phones with a flash.

Undo last mark

Take back the last tap. Shown once you have marked something.

Pause / Resume

Stop tracking for a moment without losing your marks.

✓ Finish scan

Build the room from your marks.

✕ Cancel scan

Asks first; Discard scan deletes everything captured in this scan.

Tracking quality warnings

Problems show as short warnings at the top of the screen. Do what they say:

• Tracking lost — aim at a scanned area — point back at a part of the room you already saw until it recovers.
• Too fast — slow down — move the phone more slowly.
• Too dark — turn on lights or the flashlight.
• Not enough detail here — aim at a corner, furniture or a textured surface; plain white walls are hard to track.
• Move to a new area — nothing new is being seen.
• Detail limit reached — finish the scan — finish to keep what you have.
• Mirrors, glass and people walking through make tracking worse.

Why my scan could not finish

The model is built from a closed floor outline. If you press Finish with three or more corners but an open outline, the app offers Close outline and finish. If the model still cannot be built, close the floor outline and try again.

An interrupted scan

If the app closes in the middle of a scan, that scan cannot be continued — the phone loses its tracking origin. You are asked to Keep it or Discard it. To add or edit rooms in a finished project later, use Continue: re-anchor the saved rooms by tapping the gold corner, then the blue corner (on the floor, or at the ceiling), and press Confirm anchors. Then trace a new room, or choose Opening and tap a wall of a saved room to add a door or window to it.

Which phones work

Depth scanning available

Phones with ARCore depth get the most accurate capture.

Standard scanning available

Without depth, the app uses feature points and detected planes — cover the room more carefully.

ARCore required / update required

Install or update Google Play Services for AR from the banner.

Scanning not available

The phone is not on the ARCore list. Start scan becomes Scan by aiming (below), and you can still open, edit and export projects, or draw the plan on the web.

Phones without AR: Scan by aiming

On a phone ARCore does not support, Scan by aiming measures the room with the phone’s motion sensors instead of the camera’s AR. Expect a few centimetres of error per metre — fix any wall in the plan editor afterwards.

1. 1Enter Your height (cm) — every distance is worked out from it — and press Start measuring.
2. 2Stand near the middle of the room and only turn on the spot. Hold the phone at eye level.
3. 3Put the crosshair where the walls meet the floor and tap Mark corner, going round the room in order, then Close room.
4. 4Aim at a ceiling corner above a marked one and tap Mark ceiling, or Type height (2.50 m is assumed otherwise).
5. 5Press Save room, then add doors and windows in the plan editor.

Open a finished project on the phone to see it, fix it and send it on. For full CAD drafting, open it on the web (⋮ → Open on the web).

The room viewer

• Three tabs: Floor plan, 3D and Reports.
• Show or hide dimensions, room names, area and furniture; switch to wireframe or Walk mode; open or close doors.
• Walls the camera never saw are drawn dashed — check them on site.
• The 360° icon in the top bar opens the project’s 360° pictures.

Take a 360° picture of a room

A 360° picture is a look-around photo of the room from one spot — walls, ceiling and floor — that belongs to the project. It is separate from the scan: it adds nothing to the plan or the model.

1. 1Open the project, tap the 360° icon in the top bar, then New 360° picture.
2. 2Stand in one spot. Dots appear round you on the walls, the ceiling and the floor. Turn the phone to put the circle on a dot (Follow the arrow points to the next one) and hold still — the picture is taken by itself.
3. 3The panel counts the pictures (e.g. 12 / 36) and maps what is covered. Turn the phone, not your body; if you walk off, Go back to where you started turns red and pictures stop until you do.
4. 4After the last dot it finishes by itself — or press Done any time after the first picture. The pictures are joined on the phone (Putting the 360° picture together…), then it opens to look around in.

• Lost its place — tracking dropped (a bare ceiling, for example): move slowly towards a wall with some detail.
• 360° pictures need Google Play Services for AR, like scanning.

Where 360° pictures are saved

• In your phone’s gallery, in the Pictures/3D Room Scanner folder, named pano_<project>_…. Gallery apps and Google Photos open them as 360° photos. (On phones older than Android 10 they stay in the app’s own folder instead, not in the Gallery.)
• The project’s 360° pictures screen lists only that project’s pictures, newest first, with the date and time each was taken. Tap one to look around: drag to look, pinch to zoom, and step to the previous or next picture.
• The bin icon deletes a picture — from your phone’s gallery too. Deleting the project does not delete its 360° pictures; they stay in the gallery.
• They are not uploaded: 360° pictures are not on the web and do not reach My Scans.

Edit the plan

Corners

Select a corner and nudge it with the arrows — each arrow is 1 cm.

Walls and openings

Drag a wall or an opening; add or edit an opening’s width, height and height above floor; rotate a door.

Draw walls

Polygon, Rectangle, 90° or Single wall, then Close room — this also lets you draw a plan by hand.

Furniture and blocks

Add furniture or a block, with depth and rotation.

Measure

Point to point, with snapping, undo and redo.

Calibrate with a tape measure

1. 1Measure one wall in the room with a tape.
2. 2In the plan editor, choose Calibrate and pick that wall.
3. 3Enter the true length — every measurement in the project is rescaled to match.

While you are signed in and your plan includes Sync with web, every project you create or edit on the phone uploads to My Scans by itself — no cables, no manual export.

Upload status

On this device only

Not uploaded — signed out, or cloud sync is not on your plan.

Waiting to upload

Queued; it goes as soon as you are online.

Uploading…

On its way.

Backed up

The web copy matches the phone.

Upload failed

Try again with ⋮ → Upload to cloud.

Why my scan is not on the web

• Check the project’s status on the phone. Offline, uploads wait until you are back online.
• A failed upload is not retried by itself — use ⋮ → Upload to cloud, or edit the project.
• Make sure the phone and the browser are signed in to the same account.
• Cloud upload must be on your plan (Sync with web).
• On the web, press ↻ Refresh in My Scans to fetch projects synced from the phone.

A new phone, or projects drawn on the web

When you open the app or sign in, projects that are newer on the web come down to the phone — including ones you drew in the browser. On a new phone, Profile → Restore from cloud brings all your uploaded projects back.

When the phone and the web disagree

If one copy is newer, the app tells you before replacing anything — for example Replace your unsent changes? when refreshing would overwrite edits you have not uploaded yet.

What is uploaded

Names, notes and the plan data. Camera images, raw scan data and 360° pictures stay on the phone. Signing out keeps your local projects on the device.

You do not need the phone app at all. A drawn project gets the same 2D drawing, 3D model, schedules and exports as a scanned one — scanning just saves you the measuring.

Create a project on the web

1. 1Open My Scans and press New project.
2. 2Enter a project name; client, building and floor are optional. Choose the unit: metres, centimetres, millimetres, feet or inches.
3. 3Press Create & draw. The workspace opens on an empty plan.
4. 4Draw the rooms with Rectangle (REC), Line (L) or Outline (OUT), then add doors and windows.

Opening a project from My Scans opens the CAD workspace — Projments BIM — where the plan, the 3D model and the schedules are edited together. If you have used AutoCAD, the conventions are the ones you expect.

Around the screen

App bar (top)

Back to Projects, Save, Undo / Redo, check for changes from the phone, show or hide the ribbon, the View List, Properties and focus mode.

Ribbon

Seven tabs: Draw, Modify, Annotate, View, Reports, Export and Settings. Selecting something switches to Modify.

Command line

Type a command or its alias — “L, REC, TR, CO …” — with autocomplete. See the Command reference.

Status bar (bottom)

GRID, SNAP, ORTHO, POLAR, OSNAP, DYN and JOIN toggles, the cursor position, zoom and the selection count.

Focus mode

Full screen, Fill the window, or Normal.

On a phone or small screen

A Quick tools bar, with All tools for the rest.

Saving your work

• Save with the Save button or Ctrl+S. There is no autosave — the bar shows Unsaved changes until you save.
• Leaving with unsaved work asks you to Continue editing, Discard or Save changes.
• Ctrl+Z undoes and Ctrl+Y (or Ctrl+Shift+Z) redoes. A command that repeats, such as Copy, is one undo step.

Changes from the phone

If the project was changed on the phone after you opened it, the workspace offers Load the newer version. If both changed, saving warns This project changed on another device — choose Overwrite with my version or Retry save.

Why a project opens view only

A View only badge replaces Save when:

• it was shared with you for viewing;
• it was shared with editing, but your own plan has no projects left;
• your plan does not include the Projments BIM workspace;
• it is the built-in sample project.

Type an alias on the command line and press Enter or Space. Autocomplete matches aliases first, then names. While a command runs, the line shows what it needs next and the letters of its options.

Move a wall by an exact distance

Select a wall and temporary dimensions show the distance to the nearest parallel wall on each side. Type a value to move the wall to that distance.

Selecting

• Click to select; Shift+click adds to the selection; Shift+Space cycles through overlapping objects.
• Drag left → right for a window (only what is fully inside), right → left for a crossing (anything it touches).
• One selection is shared by the 2D plan and the 3D model — pick a wall in one and it is picked in the other.

The selection filter

Click the selected count on the status bar to keep only some kinds: walls, doors, windows, archways, measurements, annotation lines, text notes, section and elevation marks, and each kind of furniture. It can open by itself after a multi-object pick (Settings → Options).

Grips

Point grips

Move one point — a wall end, a vertex, a dimension point.

Body grips

At midpoints and centres; move the whole object.

Size grips

Resize around the opposite point — a block corner, a circle, a door jamb.

Grips snap with the drafting aids. Section and elevation marks have grips for width, depth and flip.

Properties panel

Wall

Length; base level and offset; top level (or Unconnected) and top offset; height.

Door / window

Width, height, sill height, swing, and open or closed.

Room

Name, or delete the room.

Block

Type, elevation, rotation, scale, its parameters, and Edit Definition.

On the floor plan, the Draw tab’s shapes draw walls. A closed shape makes a room. To draw lines that are not walls, use the Annotate tab’s Lines (see Annotation).

Lines and rooms

Line (L)

Wall by wall, from point to point, until you press Enter or Esc. Option C continues from the last wall.

Polyline (PL)

A connected run; A switches to an arc segment, C closes it.

A room from two corners. D types length and width, A an area, R a rotation.

Outline (OUT)

Corner by corner; click the first corner to close the room.

Polygon (POL, PE)

A regular polygon from its centre (number of sides, default 6) or from one edge.

Curved walls

Circle (C, CD, C2, C3)

Centre and radius or diameter, two points, or three points. T draws it tangent to two objects.

Arc (A, ASC)

Three points, or start, centre and end.

Ellipse (EL, ELA)

From its centre, or from an axis.

The Modify tab edits the drawing. Letters in brackets are the options you can type, or tap as chips, while the command runs. Esc cancels; Enter takes the default shown in the prompt.

How a command runs

Select first, or when asked

Move, Copy, Rotate, Scale, Mirror, Array, Erase, Join and Explode work on the selection — select first and the command skips straight to its next question.

Pick as you go

Trim, Extend, Offset, Fillet, Chamfer, Break, Align, Match properties and the constraints ask you to click the objects themselves. Anything already selected is not used.

Only what you can see

Stretch, and Trim and Extend without [E], only reach what the open plan shows. Walls on other levels are never stretched or used as edges.

Numbers you type

Distances, radii and coordinates are typed in the project’s unit — in a millimetre project, 100 at Offset is 100 mm and @3000,0 is 3 m. Angles are degrees, factors and counts are plain numbers.

New walls keep their level

Walls a command makes — copies, arrays, the far half of a trim, an offset, a fillet arc — sit on the same level and top constraint as the wall they came from.

Moving and copying

Move (M) · Copy (CO)

Base point, then second point. [D] types one displacement instead, like @3,0. Copy keeps copying until Esc; [S] makes a single copy. Picking the base point again does nothing.

Doors on their own

A door or window selected without its wall moves along the wall it lands on. A door in a shared wall moves together with its twin on the other side. A copy may not overlap another opening, its own original included.

Rotate (RO) · Scale (SC)

Base point, then angle or factor — typed, or picked from the base point. [R] Reference measures the current angle or length first, [P] picks the new one as two points, [C] keeps the original and turns or scales a copy. Text turns with the walls around it. Scale changes lengths and positions only — wall thickness and height, and door and window sizes, stay as they are; a shrink that would leave a door off its wall or on top of another is refused.

Stretch (S)

Drag a crossing box, then base and second point. Wall ends inside the box move; whole objects inside move; [D] types a displacement. Doors keep their place on the wall; one that no longer fits is removed and you are told.

Mirror (MI)

Two points on the mirror line, then whether to erase the original. Door hinges and dimension lines come out mirrored correctly. Text stays readable unless you choose [T].

Array (AR)

Rows and columns (Enter for 2,3), then the spacing as a point from the centre of the selection — @dx,dy for exact spacing. [T] makes that point the total distance instead of the gap.

Polar array (ARP)

A centre, how many items, then the angle to fill (360 for a full ring). [B] gives the angle between items instead; [R] keeps the copies facing the same way. Copies are plain objects, not linked to the original.

Align (AL)

Click the edge to line up with, then the edge of the object that should move. It slides — and turns, if the edges are not parallel — until they are one line, and then waits for the next object against the same edge. A wall lines up by the face you click, so a sofa goes against the wall and two walls end up face to face.

Trimming and joining

Trim (TR) · Extend (EX)

Click the part to cut away, or the end to lengthen. Every visible wall and line is an edge; [E] picks the edges first. Works on walls and lines; a closed line needs two cuts.

Offset (O)

A parallel copy: distance, object, then the side. [T] goes through a point you pick instead, [E] erases the original. The distance is kept for the next object.

Fillet (F) · Chamfer (CHA)

Round or cut the corner between two walls or two lines. The side you click on each one is the side kept, so crossing walls can be cleaned up either way. Radius 0 just closes the corner. Chamfer: [D] two distances, [A] a distance and an angle. [T] adds the corner without trimming.

Fillet and chamfer walls

The new curved or cut piece takes the walls’ thickness and height and joins their room, and doors on the trimmed walls stay where they are.

Join (J)

Walls in a straight line that meet end to end become one wall, doors kept. Lines that meet at an end become one polyline. Walls that fold back over each other are not joined.

Break (BR)

Click a wall or line, then the point where it splits. Both halves keep their room and level.

Objects

Erase (E)

Delete the selection (or press Delete). Doors and windows in an erased wall go with it, and you are told.

Explode (X)

Break a room into free walls, a polyline into single lines, or a placed block into the blocks nested inside it — each stays where it stood, still 3D. A block with shapes of its own besides nested blocks is not exploded, so nothing is lost.

Match properties (MA)

Click the source, then each object to change. Walls take the source wall’s thickness and height; lines take its pen (weight, dash, colour). Both picks must be the same kind.

Constraints

Make a wall or line Horizontal (HZ) or Vertical (VT) with one click. For Parallel (PAR), Perpendicular (PER), Set Angle (CAN) and Equal Length (EQL), click the reference first, then the object to change — then keep clicking more objects against the same reference. Set Angle asks for the angle (Enter for 90).

What moves

The object turns the short way round its middle — or round the corner it shares with the reference, so squaring up a room never moves the reference wall. Equal Length keeps that shared corner too.

One-off, not a rule

Each one changes the geometry once. Nothing is stored, so a later edit can undo it. Picking the same object twice, or one already right, is refused with a message.

Openings are cut as real solids in their wall, so they read correctly in 3D and are deducted from wall areas in the quantities.

Place a door or window

• Draw tab → Openings: Door (DR), Window (WN) or Archway (AW).
• Click a wall. The command repeats, so you can place several — press Esc to stop.
• Scanned rooms already have the doors and windows you marked on the phone.

Change an opening

Select it and use the Properties panel: Width, Height, Sill height, Rotate swing and Open / Closed. Drag its grips to resize it along the wall. Door and window schedules list them all and let you edit sizes in the table.

Measure

Measure (DI) reads the distance between two points without placing anything. Its options also measure an angle, or an area with its perimeter.

Dimensions

Aligned (DAL)

Along the measured edge.

Linear (DLI)

Horizontal or vertical only.

Angular (DAN)

The angle between two lines.

Radius (DRA) · Diameter (DDI)

For circles and arcs: centre, then rim.

Text

Text (T): click a point and type. It repeats until Esc. The arrow beside the button sets the size — Tiny, Small, Medium, Large or Huge — and Text Settings holds the rest.

Hatching

Hatch (H): click inside a room. Patterns: Solid, Parallel Lines, Cross Hatch, Diagonal, Grid, Dots, Bricks, Concrete, Wood and Tiles.

Lines that are not walls

The Annotate tab’s Lines panel has the same shapes as the Draw tab but draws plain lines. Their aliases start with N: NL, NPL, NREC, NC, NA…

• Hide or show dimensions, room names and areas from View → Annotations.

A section or an elevation is a view of the model, not a separate drawing — change the model and every view follows.

Levels

• Open Levels in the View List to see every storey at its real height; drag a level to move it.
• Each level has a name, elevation, story height, and can be hidden or locked. When a level moves, choose whether what sits on it moves too.
• Add a level above or below, create its floor or ceiling plan, and Make active to draw on it.
• Deleting a level moves what was on it to a level you choose.

The View List

The View List button on the app bar lists every view by kind, with search: Floor Plans, Ceiling Plans, Elevations, Sections, 3D Views, Schedules and Drafting Views. Right-click a view to open it, open it in split view, rename, duplicate, lock or delete it.

Create a view

Floor / ceiling plan

Add to the group — made for the active level.

Elevation (ELV)

Add one from the group (next free North, South, East or West), or place a marker with the Elevation tool.

Section (SEC)

View → Section: draw a line through the model, then pick the side to look at.

3D view

Add to the 3D Views group.

Drafting view

A blank 2D sheet for details that are not part of the model — the Draw tab and 3D are off there.

Sections and elevations have a direction, near and far clip, and can be flipped.

Split view and tabs

View → Split View tiles every open view, so the plan and the 3D model can sit side by side. Each pane can be maximised. Open views also appear as tabs you can close, close all, or reopen.

Navigate and display

• View → Navigate: Pan (P), Zoom extents (ZE) and Rotate view.
• View → Annotations shows or hides dimensions, room names and areas — per view.
• Grid (F7) toggles the canvas grid.

A schedule tabulates one kind of element and stays tied to the model: change a wall and its row changes; edit a value in the table and the model changes.

Create a schedule

View → Schedule, or Add to on the Schedules group in the View List, then pick what it lists. The source is chosen once — for another kind of element, create another schedule.

What each schedule lists

Rooms

Number, name, level, area, perimeter, height, volume, doors and windows.

Doors

Mark, type, level, width, height, host wall, and the rooms it connects.

Windows

Mark, type, level, width, height, sill height, host wall, room and area.

Walls

Mark, level, room, length, height, thickness and area.

Furniture

Mark, kind, label, level and size.

Blocks

Mark, definition, type, level and footprint area.

Levels

Name, elevation, story height, and the rooms, walls and area on each.

Edit values in a schedule

• Editable cells include room names, opening sizes and sills, wall height and thickness, furniture labels, and level names and heights.
• Every edit is an ordinary change — Undo takes it back.
• Show Every item, rows By room, or Group identical; totals are at the bottom.

The Reports tab

Rooms opens the room schedule. Info is the project sheet: client, building, floor, notes and unit, then floor area, perimeter, height, volume, wall area (openings deducted), skirting (doors deducted), and brick and tile counts.

Every project has a 3D model built from the plan. Doors and windows are cut as real solids, so openings read correctly from inside. Switch with View → 3D, or show both with Split View.

Mouse and touch

Right-drag

Orbit.

Middle-drag

Pan (left-drag too while Pan is on).

Wheel

Zoom.

Touch

One finger orbits; two fingers zoom and pan.

View cube

Click a face, edge or corner to jump to that view.

Left-click selects, as on the plan.

Walk through the model

• Turn on Walk. You stand at eye height (1.6 m) inside a room.
• Desktop: move the mouse to look, W A S D or the arrow keys to walk; Esc leaves.
• Touch: drag to look, and use the on-screen joystick to walk.

Place furniture in 3D

Pick an item in the Library, then click the floor to place it. Keep clicking for more copies; Space rotates the piece; Esc or right-click stops.

Display and snapshot

• Show the model as wireframe or with a brick pattern, with or without dimensions, room names and areas.
• Snapshot (PNG) saves the 3D view as an image.

The Library

• Draw tab → Blocks → Library: more than 600 furniture pieces in 32 categories, from Seating to Landscape, with search.
• Pick a piece and click to place it on the plan or in 3D (IN for furniture, BI to place a block).
• Your own blocks are under My blocks, where you can edit, duplicate, rename or delete them.
• Built-in pieces cannot be changed — editing one saves your own copy to My blocks.

Build a block

1. 1In the Library, press New Block to open the Block Editor.
2. 2Add shapes: Box, Cylinder, Sphere, Cone, Extrusion, Revolve, Sweep, Blend — or a nested block.
3. 3Position, rotate and scale each one; bind its sizes to parameters so the block can be resized when placed.
4. 4Give it a category (Furniture, Doors, Windows, Fixtures, Lighting, Structure or Generic) and save it to My blocks.

Views

Perspective, Top, Front, Right, Back, Left and Isometric.

X-Ray (X) and section

See through the block, or clip it.

Undo

The editor has its own undo and redo.

Change a placed block

Select it: the Properties panel shows its type, elevation, rotation, scale and parameters, and Edit Definition opens it in the Block Editor.

Appearance

Theme

Light, Dark or System.

Drawing Surface

The canvas colour: follow the theme, always light, or always dark.

Units

Settings → Options → Length unit: millimetres, centimetres, metres, feet or inches. The unit is saved with the project and changes how lengths are shown and typed — not the drawing itself.

Keyboard shortcuts

• Settings → Keyboard Shortcuts lists every command and ribbon action by tab, with search.
• Pick one and press the keys to record it; a conflict with another shortcut is flagged. Keys the browser reserves (Ctrl+W, Ctrl+T, F5…) cannot be used.
• Commands ship without keys — type their alias, or give them one here.
• Export shortcuts and Import shortcuts move your set to another browser; Reset all to defaults starts over.

Snap, grid and polar settings are on the status bar — right-click a toggle.

Seven outputs from the Export tab. Pick by who is receiving it.

Export formats

Image (PNG)

The drawing as a 2048-pixel-wide image.

PDF floor plan

One A4 landscape page. Image-based, so Arabic text renders correctly wherever it is opened.

Vector plan (SVG)

The only vector version of the drawing — hatching and text stay crisp at any size.

DXF — 2D plan

The floor plan as CAD geometry, for AutoCAD and anything that reads DXF.

DXF — 3D model

Walls as a shell, with floors, as 3D CAD geometry.

Quantities (CSV)

Per-room quantities and totals; opens clean in Excel. Needs at least one room.

Print report

A summary page, sent to your browser’s print dialog.

DWG is not offered — DXF opens directly in AutoCAD and most CAD programs.

CSV quantities

For each room, and in total:

• Floor area, perimeter, height and volume
• Wall area (openings deducted) and skirting (doors deducted)
• Door and window counts
• Brick and tile counts

Choose what goes on the sheet

• Framing: the current view, or the full plan.
• Include: dimensions, room names, areas, hatch, text and lines.
• Drawings are always exported on a light sheet, whatever the canvas colour.

Why my DXF ignores my display settings

DXF carries the measured geometry, not your screen. Hidden annotations or a rotated view change what you see, never what the CAD file contains — and hatch, text and annotation lines are never written to DXF.

Why my export has a watermark

Some packs stamp every export with “Projments BIM”. A pack that includes No watermark removes it — see Plans and modules.

My Scans holds every project you scanned or drew, and the ones shared with you. The pill at the top shows how many projects you have used of your plan.

Find a project

• Search by project name, client or building.
• Switch between grid and list — your choice is remembered.
• Scanned and Drawn tabs appear once you have both kinds.
• ↻ Refresh fetches projects just synced from the phone.

Active, Archived, Shared and All

Active

Your projects, without the archived ones. The default.

Archived

Projects you put away. Unarchive to bring one back — nothing is lost.

Shared

Projects shared with you, and yours that you have shared.

All

Everything in the library.

Rename, duplicate, archive or delete

• Use the card’s ⋮ menu: Open, Share…, Rename, Duplicate, Archive / Unarchive, Delete.
• Delete asks to confirm — the project’s geometry and plan cannot be recovered.
• A project shared with you only offers Open; you cannot rename, archive or delete it.

Why I cannot create a new project

When your plan’s project limit is reached, New project and Duplicate open a You have reached your scan limit message with View plans. Delete a project you no longer need, or add a pack. Renaming is never blocked.

Projects belong to your account and nobody else sees them — until you share one. Sharing is per project, by email address, from the web or the phone.

Share a project

1. 1In My Scans, open the project’s ⋮ menu and choose Share….
2. 2Type the person’s email address.
3. 3Tick Allow editing to let them edit, or leave it for view only.
4. 4Press Share. They appear under Shared with.

• An address with no account yet is fine — the share starts the day they sign up with it.
• On the phone the project must be uploaded first, because people open the cloud copy.
• Sharing needs the Project sharing module on your plan; otherwise Share… is greyed out.

Change or remove access

Open Share… again. Under Shared with, switch a person between Can edit and View only, or press Remove to stop sharing with them.

What the other person can do

Shared projects appear in their library under Shared, marked with who shared them. With editing allowed they can change the drawing on the web — but they can never delete, rename or archive your project, and only you can share it further. On the phone, shared projects always open read-only.

Why a shared project opens read-only

The scanner is sold as project packs, billed separately from Projments. Compare them in the pricing page. You can start free.

Project limits

• A pack includes a number of projects in total — not per month — or unlimited.
• Packs stack: buying another adds its projects to what you have.
• At the limit you cannot create or duplicate projects, and new phone projects stop syncing, until you free one up or add a pack.

What each module unlocks

Projments BIM

The web CAD workspace. Without it, projects are view only on the web.

Export

The Export tab: PDF, PNG, SVG, DXF and CSV.

Reports

Schedules and the Reports tab.

No watermark

Exports without the “Projments BIM” stamp.

Sync with web

Uploading projects from the phone to the cloud.

Blocks

The furniture library and your own blocks.

Settings

Keyboard shortcuts and drafting defaults.

Project sharing

Sharing your projects with others.

With several packs, a module is on if any of them includes it — but the watermark is removed only when every pack removes it.

Everything is on Billing & Plan: your current plan and status, usage, payment methods, your packs and your invoices.

Buy or upgrade a pack

• Press Upgrade Plan (or Compare) and choose Get this pack, monthly or yearly where both are sold.
• Payment is by card through Stripe; the pack is active as soon as payment is confirmed.
• In the Android app, packs are bought through Google Play.

Change a pack

Under Payment & Subscription choose Change pack. Moving up applies immediately and charges the difference; moving down starts at the end of the current period.

Cancel or resume

• Cancel stops renewal — the pack keeps working until the end of the period you paid for, and the card is not charged again.
• Changed your mind? Resume Plan turns renewal back on before the period ends.
• One-off packs never renew; there is nothing to cancel.

Payment failed

A banner asks you to Update Payment; add or change your card under Payment Methods.

Invoices and receipts

Billing Documents lists every payment with its date, amount, status and a download link. Google Play purchases are receipted by Google.

Packs bought on Google Play

One account works for the scanner app, the web and Projments. Manage it on My Profile (or Edit account in the app).

Change your name, email or password

• Edit your full name and save.
• To change your email or password, enter your current password too.
• A new email does not take over until you open the link we send to it — you keep signing in with your current address until then, and that address is told about the request.
• Changing your password signs you out on your other devices, and we email you that it changed.
• Forgot it? Use Forgot your password? on the sign-in screen — in the app it asks for your email and sends you a reset link; you choose the new password on the website.

Delete your account

Contact support

• Open a support request and mention the 3D Room Scanner — we usually reply within one business day, and the whole conversation stays in one thread.
• From the phone, open the Support tab in the bottom bar and press New request: choose Bug report, Feature request or Help & guidance, write a subject and a description, and press Send request. Replies show up in the same tab and on the website.

Report a problem well

• Say whether it happened on the phone or the web, and which project.
• Describe what you did, what you expected, and what happened instead.
• A screenshot helps; on the phone, Profile → Diagnostics shows details we may ask for.

Privacy

Camera images and raw scan data stay on your phone; the cloud keeps names, notes and plan data. 360° pictures are saved to your phone’s gallery and are not uploaded by the app. The app’s Profile → Privacy explains exactly what is captured, stored and uploaded, and how to delete it. The full policy is linked in the page footer.
