Sketch on 3D Models >


Imagine if you could have a 3D model inside your sketchbook. Then, imagine that it would automatically generate perspective lines for you. And now, imagine that you could fly between views to present your work. Would you believe it? Meet the new way to sketch over 3D models.

How to Sketch on 3D Models

Step 1. Import Your 3D Model

Use any software (Autodesk AutoCad, TinkerCad, Revit, SketchUp for iPad, Rhino, Shapr3D, UMake, etc) and then export an OBJ, STL, or USDZ. Then, tap the "+" button and select "3D Model" or drag and drop in your 3D model from Shapr3D or the Files app.

Pro Tip
When you export your 3D model be sure that ONLY mesh objects are in your file (no curves, splines, NURBS surfaces, etc).


Step 2. Set Your View

Select your Camera Mode and tap with one finger to center your camera view. You can also drag one finger to orbit around the model, drag two fingers to pan across the view or pinch with two fingers to zoom in and out. When you get the view you want, tap the Green Check.

Step 3. Set Your Sun

Select Manual Mode for free movement or Location Mode to input exact coordinates. With Location Mode just input a location, date, and time to get precision shadows with "Shadow Maker". Or you can adjust the sun position freely by switching to Manual and using the dials to set the sun azimuth and elevation.

Step 4. Draw on Auto-Generated Perspective Grids

You will notice that Trace sets up the perspective lines and vanishing points for you. Simply draw away. When finished tap the 3D Model button (cube) to get more views and previews.

Step 5. Fly From Sketch to Sketch to Sketch

Ready for some fun? Simply tap any preview and fly to that view. Can you imagine a better way to present your work?
