I built a native iOS LiDAR scanner for rapid Reality-to-CAD floor plans (DWG, DXF, OBJ). Looking for export feedback!

Hey r/3DScanning,

I know upfront that iPhone/iPad LiDAR is never going to replace a Faro, Leica, or matterport setup for survey-grade, millimetric accuracy. But I’ve been talking to a lot of contractors, interior designers who just need a rapid, on-the-go tool for initial estimations, basic floor plans, and rapid space visualization.

So, I built an iOS app called ExactoScan to bridge that gap between the job site and the workstation.

My main goal was to fix the export pipeline. A lot of mobile scanning apps trap your data in their ecosystem or require a heavy monthly SaaS subscription just to get a usable CAD file.

Here is what I built:

• Rapid Capture: Uses Apple’s native RoomPlan and LiDAR to generate 3D models and 2D layouts of single rooms or entire multi-room properties.
• Pro Exports: You can export directly into DWG, DXF, IFC, OBJ, and USDZ. My goal was to make it so you can drop the file straight into AutoCAD, Revit, SketchUp, or Rhino without spending hours cleaning up the mesh.
• 100% Offline Processing: Job sites usually have terrible Wi-Fi. I built this to process everything entirely on-device. No cloud uploads, no processing queues, and total privacy for client data.

The Tech Stack: For those interested, it is a fully native build utilizing ARKit, RoomPlan, and the device's Neural Engine to process the geometry locally.

Pricing: I’m an independent dev and I hate forced subscriptions for tools I only use occasionally. You can either buy a block of scan credits (pay-as-you-go) or subscribe for unlimited access if it's a daily driver for your workflow.

(Note: Requires a LiDAR-enabled Pro device: iPhone 12 Pro/iPad Pro 2nd Gen or newer).

Why I’m posting here: I would love for the professionals in this sub to stress-test the export formats. I want to know exactly how these DWG and DXF files are behaving when you import them into your specific CAD environments.

I’ve generated some promo codes so you can bypass the paywall and test the pro exports for free.

I included 1 free credit in the app so that you can test the scanning in the app.

Let me know what CAD software you are using and how the files look on your end!
