Step 2. Change Background

You can always change the background of your project to any drawing, image, template, or paper type.

Pro Tip
Once you change the background, you can change it again, but you cannot undo this change. We highly recommend not changing the background for a 3D model or map project as you will not be able to get back your model view or map view after you change it.

Step A. Change Background

Tap "Change Background" to replace the background.
