How to Import 3D Models

You can import a 3D model into Trace from any 3D model software.


Step 1. Create Your 3D Model

Use your preferred 3D model software including SketchUp for iPad, Shapr3D, AutoCAD, Rhino, Revit, 3DS Max, TinkerCAD, or UMake to create a 3D model.

Pro Tip
Trace is a 2D drawing app so be sure to do all of your 3D modeling in your favorite 3D modeling app.

Step 2. Export Your 3D Model

Export your 3D model as an OBJ, STL, DAE, 3DS, or USDZ file. Be sure that you only have mesh objects in your file (no curves, splines, NURBS surfaces, etc). If you create your 3D model in SketchUp for iPad, you can tap "Export USDZ" and open the file directly in Trace.

Pro Tip
If you need help with this, just search for how to export an OBJ file from your preferred 3D model software.
