How to draw and edit plans in the vPlan AR web editor: walls to exact lengths, levels and stairs, doors and windows, snapping, finishes and design options.
Yes. Any scan you save on your phone syncs to your account automatically, on every plan, Free included. Sign in at vplan.ai, go to Projects, and open the scan to edit it in the full web editor. Changes you make on the web come back to the app when it syncs: when you open the app, pull down on Projects, or tap Sync Now in Settings.
In the floor plan editor, the "Levels" panel is on the left of the drawing. Click the + button and choose a preset — Basement, Main Level, Level 2, Level 3 or Attic — then adjust the name, elevation, ceiling height and floor structure if needed. The floor structure is the floor the level stands on: an 11 7/8" I-joist floor by default, or 2x10 or 2x12 joists, an 8" concrete slab, or your own thickness. A new level stacks at the ceiling height of the level below plus its floor, so with the defaults Level 2 sits at 9 ft + 13 7/8". When you change a level's ceiling height or floor, the levels above it (below it, for a basement) move with it, so their floor-to-floor heights stay the same (untick "Move the other levels" in Edit Level to keep them where they are). You can then scan or draw each level independently. In the 3D view, all levels are shown together with their correct vertical offsets and floor thickness.
Stairs are on Pro and Business. Press S (or click Stairs in the toolbar), pick Straight, L-Shaped, U-Shaped or Spiral, and click to place it on the level it starts from. It goes up to the next level and fits itself to that rise: the risers, riser height and tread depth follow the code you choose, IRC (residential) or IBC (commercial). In the stair panel you can pick the level it goes up to, change the code, click "Fit to levels" again after editing the levels, or edit the risers, tread depth or run (the others follow). L- and U-shaped stairs also have a Landing depth, which starts out as deep as the stair is wide: a deeper landing moves the second flight, the floor opening and the 3D stair with it, and an L landing can't be made shallower than the stair is wide. "Turns (walking up)" sets which way an L- or U-shaped stair turns at its landing, left or right; mirroring a stair turns it the other way too, and its symbol, floor opening and 3D stair follow. "Flight direction" sets which end the stair climbs from, "Up from start" or "Up from end": the stair stays exactly where it is, and Up from end puts the bottom step and UP at the far end, so the break line, the floor opening above, the DN arrow and the 3D steps all follow (an L- or U-shaped stair walked the other way turns the other way, as "Turns (walking up)" shows). The checks below them flag a riser, tread or width outside the code (a U-shaped stair's width is checked per flight, since its two flights share it; a new U stair starts 1.99 m wide, two 36" flights), a landing shallower than the flight it serves, and a flight that rises more than the code allows between landings (151" under IRC, 12 ft under IBC), and show how long the opening in the floor above must be for headroom. While you place or drag a stair, its start and sides snap to a room edge with no wall along it, and a stair pointed at or away from a wall meets the wall with its end. On its own level the stair is drawn going UP with a break line at the 4 ft plan cut and the treads beyond it dashed; on the level above it is drawn going DN through its floor opening, which follows the stair when you move it. Both appear in the PDF plan set and the DXF.
For a two-storey foyer or living room, open the upper level, click "Floor opening" in the toolbar (Pro and Business), then click two opposite corners of the open area. For an L-shaped or angled opening, choose Polygon under Shape in the Properties panel and click each corner in turn (or type a length and press Enter, as with walls); click the first corner or press Enter to close it, Backspace takes back a corner and Escape cancels. It is drawn with a guard line along its open sides, an X and "OPEN TO BELOW"; the floor is cut through in the 3D view; and the area comes off the upper floor's square footage in the GLA report, as ANSI Z765 measures it. Click inside the opening to change its type (open to below, chase or shaft, or other), its label, or to delete it, and drag it to move it. To reshape it, drag a corner, drag the + on an edge to add a corner, or pick a corner and press Delete to remove it (an opening keeps at least three); each change is one undo step. You don't need to draw openings for stairs: each stair adds the opening it needs to the floor above.
Use "Underlay" in the Levels tab of the web editor's right-hand panel: Below shows the nearest level below the one you are editing, faintly in blue; Above shows the level above in amber; Both shows both; Off hides it. It shows walls, room outlines and stairs, and you can't select or move it. While it is on, a new wall that starts or ends near one of its walls snaps onto it, so the outside walls of an upper floor line up with the floor below. Your browser remembers the choice.
New iPhone scans open square: vPlan AR turns the plan so its main walls run across and up the screen and the page. Plans scanned with older versions of the app can sit at an angle, often about 45°, because the scan follows whichever way the phone faced when it started. In the web editor such a plan shows "Plan is …° off square" in the top-right corner of the canvas: click Square up. You can also open the north arrow in that corner (or press ⌘K and type "square") to square the plan or turn it 90° either way, for example so the street side faces the bottom of the page. Every level turns together, and comments, review markup, photo pins, sheets you laid out and the north arrow move with it. Undo on the message that appears turns it back. The same corner sets north: the iPhone records it from its compass while you scan (shown as an approximate "≈N", since steel and appliances indoors can bend a compass), or type a bearing, or click Up. North appears on the plan, on the PDF plan set, on share links and in DXF files.
Corner misalignment usually happens when two walls are drawn very close but not exactly touching. Use the Select tool to click a wall endpoint and drag it onto the adjacent wall's endpoint: it snaps the same way as drawing a wall, and a square marker appears when the ends meet. When you draw a new wall, object snaps (OSNAP in the status bar) put its ends exactly on another wall's end, middle or side. You can also turn on SNAP in the status bar at the bottom of the editor to force walls onto the measurement grid (the grid size is next to it). If walls still gap after snapping, check that both endpoints share the exact same coordinates in the Properties panel.
Press W (or click Wall), click where the wall starts, then type its length: as soon as you type a number, the box beside the wall takes it. Feet and inches work the way you write them (14'6, 13' 8 1/2", 12'+6"), and so do metres (4.2m, 420cm); a plain number is feet in imperial and metres in metric. Press Tab to give an angle as well, in degrees counter-clockwise from the right (90 is straight up the screen), and Enter to add the wall. The next wall starts from its end, so you can type a whole room: 12, Enter; Tab, 90, Tab, 10, Enter; and so on. Clicking adds a wall and carries on in the same way. Enter with nothing typed or a double-click finishes, and clicking the first corner again closes the room and finishes. Esc clears what you typed, then stops drawing. Ctrl+Z (⌘Z) while drawing takes back the last wall and carries on from where it started.
With the Wall tool picked, the Properties tab shows the wall type new walls get, such as Exterior 2x6 (6 1/2") or Interior 2x4 (4 1/2") in imperial, or Exterior 200 mm or Interior 100 mm in metric, and the line you draw along: the centre line, the interior face or the exterior face. Drawing along a face lets you click the finished inside dimensions; draw rooms clockwise so the interior is on the inside, and the corners join up by themselves. Select a wall to change its type or type a thickness, and choose which face stays where it is when the thickness changes; walls joined to it stretch to meet it again. "Manage wall types…" adds your own types to the plan: give one a name and a thickness, and changing the thickness later changes every wall of that type. Wall types go into the IFC export as wall types.
Press Q (or click Measure in the tool rail) and click two points. The distance shows beside the line, with how far across, how far up or down and the angle; it uses the same snaps as drawing walls. Nothing is added to the plan. Click again to measure somewhere else, and Esc clears it. To keep a dimension on the plan and the PDF, use the Dimension annotation (M) on Pro instead.
With the Select tool (V), hold Shift and click to add something to the selection or take it out. To select with a box, drag across a room's floor, or hold Shift and drag anywhere: dragging left to right takes what is wholly inside the box (a solid box), and right to left also takes what it touches (a dashed green box). Ctrl+A (⌘A on Mac) selects everything on layers that are shown and not locked. Drag any selected item to move them all together, or nudge them with the arrow keys; walls joined to them stretch to stay joined. Delete removes them all as one step, and Esc clears the selection. The Properties tab and the status bar show how many of each kind are selected.
Select one or more items and look in the Properties tab. To rotate them by any angle, type it under Turn (degrees counter-clockwise; −30 turns clockwise) and click Rotate: they turn about their centre. To turn them about a point on the plan, pick Rotate selection on the tool rail (or "Rotate selection" in the Ctrl+K / ⌘K palette), click the base point (it snaps to wall ends, middles and crossings, or press Enter for the centre of the selection), then click to set the angle, measured from the base point with 0° pointing right; Polar tracking snaps it to its steps (15°, 30°, 45° or 90°) and Ortho to quarter turns. You can also type the angle and press Enter at any point. Walls turn with their doors and windows; rooms, furniture, stairs and floor openings turn too, and notes and dimensions move round with them. R turns the selection 90° (Shift+R the other way). Mirror flips them left–right or top–bottom about their middle; tick "Keep the original" to mirror a copy instead. Mirrored walls keep their inside face inside, and doors keep opening the same way. Array makes a row of copies: set how many, the direction and the spacing (copies sit edge to edge until you type a spacing). With two or more pieces of furniture, stairs, notes or floor openings selected, Align lines up their left, centre, right, top, middle or bottom edges, and with three or more Space evenly sets equal gaps between them; walls stay where they are. Walls of the same thickness selected along one straight line can be joined into one wall, and their doors and windows move onto it. Every command is one undo step.
Select what you want and press Ctrl+C (⌘C on Mac), or use Copy in the Properties tab; Ctrl+X cuts. Go to the other level, or open another plan in the same browser, and press Ctrl+V (⌘V). On another level of the same project the copy lands in the same place, lined up through the levels' alignment; in another plan it keeps the same coordinates. Pasting on the level it came from puts it just beside the original, and Ctrl+Shift+V (⇧⌘V) always pastes in the same place. Walls bring their doors, windows and wall types with them, and a selected room copies as its walls with its name. "Copy to level" in the Properties tab does all of this in one step. Ctrl+D (⌘D) duplicates on the same level, just beside the original.
Offset (P) draws a wall parallel to another: click a wall, then click the side the new wall goes on. It follows the cursor in grid steps, or tick "Fixed distance" in the Properties tab and type one. If the wall you click is part of a selected run of walls, the whole run is offset with its corners joined, which is a quick way to draw the inside of an outline. Trim / extend (X) makes two walls meet at a corner: click each wall on the part you want to keep, and each is cut or lengthened to where their centre lines cross. Set the mode to "To a boundary" to change only the second wall, for a T-junction. Doors and windows cut off by a trim are removed. Esc lets go of the first wall.
While you draw, the point snaps to what is near the cursor and a marker names it: a square on the end of a wall, a triangle on its middle, an X where two walls cross, ⊥ for square to a wall from the last point, an hourglass for any point along a wall, and + for a wall carried on past its end. Wall faces snap too, with the same markers labelled for the face: "Face corner" on the corner of a face (inside or outside a room, or the end of a free wall), and ⊥ and the hourglass on a face, so a wall can stop flush against one; where the end of a wall and a face corner are equally close, the end of the wall wins. When the wall tool draws along the interior or exterior face, face corners win instead, and the line also stops where it meets a face and carries a face on past a wall's end, so a new wall can continue another's face flush. A dotted line from the last point shows Polar tracking, which locks every 45° (pick 15°, 30° or 90° in the status bar), or Ortho, which keeps walls straight across or up and down; // marks a wall the line is parallel to. Along a locked line the length goes in grid steps while SNAP is on, and it snaps to where the line meets another wall. With the underlay on, markers on the level below are blue and on the level above amber. Dragging the end of a wall that is already drawn snaps the same way, measured from the wall's other end (so ⊥ squares it to another wall); hold Alt (Option on a Mac) to drag it freely. OSNAP (F3), ORTHO (F8) and POLAR (F10) in the status bar turn them on and off, and holding Shift while drawing flips Ortho. Your browser remembers these settings.
Drag furniture, a fixture, a cabinet or a stair near a wall and it sits flush against the wall's inside face, turned to the wall at whatever angle the wall runs. Beds, sofas, cabinets, appliances, toilets and tubs put their back to the wall and face into the room; tables, chairs and stairs being moved just turn square to it, and a new stair from the Stairs menu runs along it (or, pointed at or away from the wall, meets it end on). A stair's start and sides also snap to the edge between two rooms where there is no wall, with that edge highlighted. Along the wall it slides into a corner and stops at the wall that meets it. Items also line up with other furniture in the same room (edges side by side or centres in a row, shown by a dashed line), with the middle of the room and with guides, and otherwise follow the grid while SNAP is on. Picking an item from the Furniture or Stairs menu works the same way: it lands against the wall under the cursor. While you drag, the distances to the walls around the item are shown; select it and click one of those distances to type a new gap, such as 2' or 600 mm. Drag the round handle to turn an item: it snaps to the angle of the nearest wall and to 15° steps. R turns the selection 90° (Shift+R the other way), and the Properties tab takes a typed angle. Text notes, arrows and dimensions snap to wall corners and faces and to the edges of furniture and stairs, so a dimension can measure a room face to face. Doors and windows snap to the middle of their wall and to a 4" (100 mm) return from a corner or the next opening, with the clear distance on each side shown as you slide them. Hold Alt (Option on a Mac) to place, drag or turn anything without snapping; OSNAP (F3) turns these snaps off too.
Yes, on every plan, for rooms named as a bedroom, living or family room, dining room or office that have no furniture yet. In the web editor, select the room and click "Furnish this room" under its properties, or click an empty part of the plan and use "Furnish rooms" (also in the ⌘K palette) to do every such room at once. Bedrooms get a bed sized to the room, a wardrobe or dresser and, in larger rooms, a desk; living rooms a sofa with a TV stand facing it, a coffee table and an armchair; dining rooms a table with chairs; offices a desk, a chair and a bookshelf. Pieces stand against walls facing into the room, clear of doors and openings, with tall pieces and beds kept off window walls where possible. Rooms that are not roughly rectangular, or that have furniture already, are left as they are. It is a starting layout: move, turn, swap or delete anything, and Undo takes the whole layout back. Name a room first if it has no name (see "How do I name rooms that have no name?").
Select a room in the web editor and open Finishes in the Properties tab (Pro and Business; the Free plan can finish one room and see it in 3D Design mode). Pick a floor (hardwood, vinyl plank, laminate, tile, marble, stone, carpet, concrete and more), a ceiling, a baseboard, and a paint for the walls; the paint goes on every wall face that looks into that room, so the room next door keeps its own colour. For an accent wall, select the wall instead: Paint lists each face by the room it looks into (or Outside face), and you paint just that one. The room fills with its floor colour on the plan and painted faces show as a coloured band. Choose New custom… for your own finish: give it a name, a colour (type the hex code, use the colour wheel, pick it from anywhere on screen in Chrome or Edge, or click a spot on a photo), and optionally a brand and colour or product code, the plank or tile size and pattern, and a cost. Custom finishes are saved with the project. Finishes appear in the room schedule export, and undo takes back any change.
Open the 3D view in the web editor and turn on Design mode (every plan; on Free you can change the finishes of the one room you finished). Floors, wall paint and ceilings show in their finishes: planks, herringbone and tiles are drawn at their real size with grout, and each wall face shows its own paint. Choose Day, Evening or Overcast lighting; Day and Evening cast sun shadows, and Evening adds a warm light in each room. Click a floor or a wall in the model to choose its finish there and then: the picker opens in the side panel, each change is one undo step, and the plan, takeoff and exports update with it. Walk through puts you inside the largest room at eye height: drag to look around, W A S D or the arrow keys to walk, Shift to go faster, and Esc to stop. To change finishes on another level, switch to it first.
Give rooms finishes in the web editor (Pro and Business) and each one shows its quantity under it. Floors use the room's area less any opening in the floor, plus waste by pattern: 7% laid straight, 15% diagonal, 20% herringbone or chevron; give a custom floor the area a box covers and the order rounds up to whole boxes. Wall paint uses each wall face's length inside the room times the ceiling height, less the doors, windows and cased openings in it, at 2 coats and 350 sq ft per gallon (about 8.6 m² per litre), rounded up to whole gallons per colour, or whole litres when you work in metric. A paint ceiling works the same way; a ceiling leaves out the stairwells and other openings in the floor above it. Baseboard runs along the walls less doorways, plus 10%. Click an empty part of the plan to see the takeoff for the whole project, every level, and to change the coats and coverage. A custom finish can carry its own waste and cost. The takeoff exports with Schedules (a Finishes tab in Excel or CSV), on the PDF schedule sheets as a finish schedule and material takeoff, and in the Cost Estimate, which prices each finish at its own cost or else at your rate card.
Open the Boards tab in the web editor's inspector (Pro and Business), or select a room and choose Mood board under Finishes. Each room has its own board, and each level has a General board for things that aren't about one room. The top of a room's board lists the finishes the room uses (floor, each wall paint, ceiling, baseboard), so it always matches the plan. Below it, add cards: + Finish pins any finish from the library as an option without changing the plan; + Product takes a name, a link to the product page, an image (upload one or paste an image link), brand, code, price and notes; + Image adds a picture with a caption; + Note adds text. Use the arrows on a card to reorder it, ✎ to edit it and ✕ to remove it; each change is one undo step. Uploading images needs the project saved to the cloud. Boards are saved with the plan and stay with their room when you move walls. In the 3D view's Design mode, Save view to mood board adds the current view (lighting and walk-through included) to the board of the room you last clicked, or to General. To print the boards, tick Mood board sheets in Export → PDF: every board with cards prints on its own sheets after the plan sheets, with uploaded images, products with their price and link, pinned finishes as swatches and notes (images linked from the web print as their address). With design options, choose Open option to print the boards of the option that is open, or All options to print every option's boards one option after another, each heading naming its option (KITCHEN — OPTION B). In the Sheets view, Add → Mood board places one room's board, the General board or every board of a level on a sheet.
In the web editor (Pro and Business), open the Boards tab, or Design mode in the 3D view, and choose + Option. Copy of this design makes Option B from what you have now, so you only change what differs; As-is (before) adds the space as it is today, with no finishes or mood boards and only the furniture the scan found. Each option keeps its own floors, wall paint, ceilings, baseboards, mood boards and furniture on the same walls and rooms; walls, doors and windows are shared, so a layout change shows in every option. Click an option to open it; switching is one undo step. Takeoffs, estimates, schedules and exports use the option that is open. Options cover the whole project: adding, switching, renaming or deleting one does it on every level, and each level keeps its own design in each option (a new option starts on each level as a copy of what that level has open, and a level added later gets the same options). Undo takes back a switch on every level at once. Rename or delete the open option under its name; deleting the last but one leaves a project with no options. With the design presentation on, the share link shows the options as one row of tabs for every level (As-is labelled before), the 3D view follows the tab, and a client's Approve or Request changes is recorded for that option. To weigh two options, choose Compare (next to + Option, or Compare design options in the command palette; on a project with several levels, pick the level to compare on): the two plans, or the two 3D models, sit side by side and pan and zoom together, and below them is what differs: floor, ceiling, baseboard and wall paint per room, mood board cards, furniture only one option has or that moved, the quantities the takeoff orders, the cost of finishes that have a price and the total of the product prices on the boards. Open an option from there to switch to it.
Open Share in the web editor, create the review link and turn on Show the design presentation (Pro and Business). Anyone with the link then sees, above the plan, each room that has finishes or a mood board: its floor, wall paint, ceiling and baseboard with brand and code, and its board cards with images and product links. A 3D view shows the finishes on the model, with Day, Evening and Overcast light and a walk-through of each level (drag to look; W A S D or the on-screen arrows to walk). Product prices stay hidden unless you also turn on Show product prices. With Let viewers comment and mark up on as well, each room gets Approve and Request changes: the client adds their name (and, for changes, what to change), you get an email, and the decision shows in the Comments tab with the room's name, pinned in the room on the plan. Resolve it there when you have made the change. Turning off the presentation, or stopping sharing, hides it again straight away.
Select the "Door" or "Window" tool from the tool rail on the left. Click on the wall where you want to place the opening — the tool automatically centres the element at your click point. You can drag the handles to resize or reposition it. In the Properties tab on the right you can type the exact width the way a drawing reads it (2' 8", 32", 0.8 m or 800 mm), and set the type (single, double, sliding for doors) and sill height (for windows).
Press ? in the editor to see every shortcut. Tools have single letters: V Select, W Wall, D Door, N Window, O Opening, R Rotate plan (with something selected, R turns it 90° instead), Q Measure, P Offset, X Trim / extend, C Comment, F Furniture, and on Pro S Stairs, T Text note and M Dimension. Esc cancels what you are doing and returns to Select. Undo is Ctrl+Z (⌘Z on Mac) and redo is Ctrl+Y or Ctrl+Shift+Z (⇧⌘Z on Mac). Delete or Backspace removes the selection. Shift-click adds to the selection, and Ctrl+A (⌘A) selects everything. Ctrl+C, Ctrl+X and Ctrl+V (⌘C, ⌘X, ⌘V) copy, cut and paste, also between levels and plans; Ctrl+Shift+V (⇧⌘V) pastes in place. Ctrl+D (⌘D) duplicates the selection, and the arrow keys nudge furniture, stairs, annotations or several selected items (hold Shift for 10× steps). Tab rotates an item you are placing by 45° and R by 90°; hold Alt (Option) to place or move it without snapping. To rotate the selection by any angle, pick Rotate selection on the tool rail or in the palette, then type the angle and press Enter (or click a base point and an angle). Ctrl+K (⌘K) opens the command palette, where you can type the name of any tool or action and press Enter. Ctrl+S (⌘S) saves, and Page Up / Page Down switch to the level above or below. While you draw a wall, type a length and press Enter (Tab moves to the angle); Enter with nothing typed finishes. F3, F8 and F10 turn object snaps, Ortho and Polar tracking on and off.
Yes. The web editor draws on a dark canvas to match the rest of the editor. Click PAPER in the status bar (or turn on Paper in the Layers tab) to draw on a soft white sheet with black walls and linework, the way the plan prints; click it again to go back to dark. Your browser remembers the choice. The canvas also shows the plan set's annotations as the PDF draws them: room names with their sizes, areas and ceiling heights, the dimensions around the outside, and door and window sizes. Walls that are not part of a room yet keep their own length labels. Turn "Plan set annotations" off in the Layers tab to hide them.
Pick a drawing scale in the status bar, such as 1/4" = 1'-0" or 1:50, and the zoom shows as a percentage of it: 100% is that scale at its real size, so a foot of plan is a quarter of an inch on the screen at 1/4" = 1'-0". Click the percentage to go back to 100%. Screens differ, so choose "Calibrate…" in the same list, hold a bank card against the screen and move the slider until the outline matches the card; after that 100% is true size on your screen. The plan set annotations are drawn at the chosen scale, so at 100% the canvas reads the way the sheet prints.
Rulers along the top and left edges show feet and inches or metres (up is positive, as in the cursor position), with a mark where the cursor is. Drag down from the top ruler for a horizontal guide, or right from the left ruler for a vertical one; guides land on the grid while SNAP is on. With the Select tool, drag a guide to move it, or drag it back onto its ruler to remove it. Walls snap to guides and to where guides cross walls or each other. Guides are saved with the level and adding, moving or removing one can be undone; they never appear in exports. The Layers tab turns the rulers off.
The drawing tools run down the left edge, each with its shortcut letter (W for Wall, D for Door and so on); room shapes, stairs, furniture and annotations open a picker. The plan fills the middle, and opening a project zooms to fit the whole plan. On the right, the inspector has tabs: Properties (whatever you selected; selecting something brings it forward), Layers, Levels, and for a saved project Photos, Details and History. Lengths in Properties take feet and inches or metres, and simple sums such as 12'+6" or 3*4'. The top bar has the project name (click it to rename), the level you are editing, undo and redo, the save status, 2D and 3D, Ask AI, Share and Export. Rulers run along the top and left of the plan. 2D, 3D and Sheets at the top switch between drawing the plan, the 3D view and laying out the printed sheets. The status bar along the bottom shows the cursor position, grid snap and grid size, object snaps, Ortho and Polar, units, the selection, Paper, the drawing scale and the zoom (Fit zooms to the whole plan). Press Ctrl+K (⌘K) to find any tool or action by name. The Inspector button in the top bar hides or shows the right-hand panel; on a tablet it slides over the plan and opens when you select something. A new, empty plan offers "Open sample house", a finished seven-room plan to try the tools on.
Yes. Open vplan.ai on your phone, sign in and open a project from Projects. You can pinch to zoom, drag to move around, switch levels, read any wall, room or door by tapping it, and export. On Pro and Business you can also mark the plan up with notes, arrows and dimensions, which save with the project like any other edit. Drawing and changing walls, rooms and openings needs a tablet or computer; scanning a new plan is done in the iPhone app.
Yes, once a plan is a project. A new plan is saved the first time you click "Save project" and give it a name; after that every change saves itself a couple of seconds after you stop, and the top bar shows "Unsaved changes", "Saving…" or "Saved just now". If a save fails (for example when you are offline) it shows "Couldn't save" with a Retry button, and your browser warns you before you close the tab. On Pro and Business, Ctrl+S (⌘S) or "Save a version now" in the History tab also keeps a version you can restore later.
Open the History tab and click Compare next to a version (Pro and Business). The plan shows what changed since then on the level you are editing: new walls, doors, furniture and notes in green, removed ones in red dashes where they were, and changed ones in amber, dashed where they were and solid where they are now. A bar above the plan counts them and shows the change in floor area, and the History tab lists each change (for example "Kitchen bigger, +24 ft²" or "Door moved"); click one to centre it on the plan. The comparison follows your edits as you work. Switch levels to compare another level. "Restore" in the bar puts that version back; Done closes the comparison. To compare two saved versions with each other, pick the other one in "Compare with" at the top of the change list (it reads "Current plan" until you do): the older one is always the starting point, and the plan shows the newer one, read-only, until you pick Current plan again or press Esc; Restore puts back the older one.
On mobile, go to Settings → Preferences and toggle the "Measurement Units" control between Imperial (ft/in) and Metric (m/cm). On the web, open Settings and choose Imperial or Metric under "Measurement units", or click the units label (ft-in or m) in the editor's status bar. The change applies instantly across all dimensions shown in the editor and in exported documents.
