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?

Today, meet Drag’n’Fly­ — the new way to sketch over 3D models. It’s truly this simple:

.

1. Import your 3D Model

Any OBJ or STL file will work. Simply, tap the 3D file icon or “Drag and Drop” in your file. Not seeing these buttons? Ensure you have the latest update here.

Pro Tip:

When you export your 3D model be sure you check the following:
1. Model units are in meters or feet.
2. Model is at the origin (0,0,0)
3. ONLY mesh objects are in your file (no curves, splines, NURBS surfaces, etc).

.

2. Set Infinite Views

Tap the “+” or simply move the screen to spin, zoom or fly around your 3D file. Set as many views as you want by tapping the check. When you’re ready to start drawing just tap the back button.

Pro Tip: Tap the model to re-center or outside the model to zoom out. Long press views to edit.

.

3. Draw on Auto-Generated Perspective Grids

Smile. You will notice that Trace sets up the perspective lines and vanishing points for you. Simply draw away. More information on drawing perspectives here. When finished tap the 3D button to get more views and previews.

4. 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?
