How the as-built apps compare

Three questions decide it: who draws the plan, how soon you have it, and what CAD file comes out.

Why PlaceAnew is the pick for homes

• One walk, every file. The floor plan with every room named and measured and the doors and windows in place, a 3D model with the furniture, a PDF report and a DXF. The PDF also has a property summary page: total and livable area, perimeter, wall area, average ceiling height, and door and window counts.
• Checked against a measured plan. In our office test, every wall we could compare one to one came within 2.5 inches of a hand-measured floor plan, with a median of 0.9 inch, from one walk and no hand edits.^[1] We publish every row: our office, wall by wall.
• Go back without going back. Walk replays the video of your visit, so you can look at a corner, an outlet or a window again from the office.
• Honest about gaps. A wall it could not see is drawn dashed and estimates are marked, so the drawing never passes off a guess as a measurement. What the scan missed, from a water heater to an electrical panel, goes in from Add › Objects, one of 46 everyday pieces.
• Free in early access. Scanning, floor plans, 3D, editing, the kitchen designer with prices and exports are free. Files shared from a free account carry a small "Made with PlaceAnew" line.

How accurate is an iPhone as-built?

Close enough to design, price and draw the existing-conditions sheet from. Here is the evidence, each piece for what it is:

• Our office test. All 7 wall lengths that compare one to one came within 2.5 inches of the measured plan. It is one unit, measured by us, with the raw rows published.^[1] PlaceAnew draws interior walls as lines, so a room next to one can read a little large: the meeting room came out 203 sq ft against 195.^[1]
• Independent research on the same Apple technology. In a 2026 peer-reviewed study, an app built on Apple's RoomPlan found all 8 rooms of a house and came within about 5% of a laser-scanned model's total room area. Wall thickness and drift between rooms were its weak points.^[21] PlaceAnew straightens the walls after the walk, and in our office the longest wall, 17' 2", came out a third of an inch long.^[1]
• What the others say about their own. Polycam says its plans measure within about 0.5 inch on standard interiors, and that complex spaces or partial coverage can widen that; that is its own figure.^[9] FARO says SiteScape is not as accurate as a traditional 3D laser scanner.^[10] Twindo has human modelers review every deliverable.^[3]

Whatever the app, start the drawing from the scanned plan, title the sheet "Existing conditions", and design on it. The steps are in how to create an as-built floor plan, and the difference between the terms is in what are as-built drawings.

The other apps, and where each is strongest

Twindo: modelled CAD and BIM, by people

Native Revit, SketchUp, IFC, Chief Architect, Archicad and Vectorworks files, and a 2D AutoCAD DWG with a dimensioned PDF.^[2] Human modelers review every deliverable.^[3] It is priced by the square foot, so a 1,500 sq ft home's 2D plan is $270 on Starter by our arithmetic, in about 3 business days.^[13][12] PlaceAnew vs Canvas (Twindo).

magicplan: plans with reports and estimates

2D and 3D plans in real time with LiDAR,^[4] with Xactimate ESX and CoreLogic FML on PRO for North American users.^[5] Its DXF comes without dimensions.^[14] It also works without LiDAR, which it needs only for Auto-Scan.^[22] PlaceAnew vs magicplan.

RoomScan Pro: laser measures and survey numbers

Works with Bosch and Leica Bluetooth laser measures and has a Touch Mode for any device.^[6] It measures ceiling heights and works out wall areas and heat-loss figures,^[6] and exports IFC, DXF, ESX and many trade formats.^[7] PlaceAnew vs RoomScan Pro.

Polycam: a mesh and a plan from one scan

Polycam pitches one phone scan for floor plans, as-builts, estimates and CAD-ready exports.^[23] A Space Mode scan gives a 3D mesh, a 3D floor plan model and a 2D plan;^[8] the plans export as PDF, DXF, PNG or SVG on Business, $400 a year per user.^[9][18] PlaceAnew vs Polycam.

SiteScape: point clouds for construction

RCP, E57 and PLY files for CAD and BIM software, and an Order BIM service that returns editable BIM and CAD files in as little as one business day.^[10] Building-scale capture up to 5,000 ft² needs SiteScape Pro.^[11]

CubiCasa: listing plans with a CAD add-on

Drawn by CubiCasa after upload and checked by a QA engineer, within 24 hours;^[19] CAD files are a $35 add-on to the $15 PLUS plan.^[20] It runs on iPhone XR and newer and on Android, with LiDAR optional.^[24] PlaceAnew vs CubiCasa.

Questions people ask

Does PlaceAnew export DXF?

Yes. PlaceAnew exports PDF report, SVG drawing, DXF for CAD and USDZ 3D model, free in early access.

Can an iPhone app give me a Revit model?

Not on the phone. Twindo's modelers build Revit, SketchUp, IFC and Chief Architect files from a LiDAR scan,^[2] and FARO's Order BIM returns BIM and CAD files from a SiteScape scan.^[10] Matterport's CAD and BIM files need a Pro-grade camera.^[25] PlaceAnew gives a 2D DXF and a USDZ 3D model, not a BIM model.

Which as-built apps work without LiDAR?

magicplan needs LiDAR only for Auto-Scan,^[22] RoomScan Pro has Touch Mode and laser measures,^[6] and CubiCasa runs on iPhone XR and newer and on Android.^[24] Twindo, SiteScape and Polycam's floor plans need a LiDAR device,^[26][11][9] and PlaceAnew needs iPhone 12 Pro or a newer Pro model, or an iPad Pro from 2020 or later.

Should I call it an as-built or an existing-conditions plan?

For a remodel, a measured plan of what stands there today is an existing-conditions drawing, and titling it that way says exactly what the drawing records. See what are as-built drawings.

Is PlaceAnew on the App Store?
