It seems I shouldn't have to ask this question, but I created a power plane, but now I want to delete it and I can't seem to find the way to select it and delete it. Can someone tell me how? I should mention this is my first use of ultiboard.
1. Check in which layer you placed the powerplane. 2. On your design toolbox select that layer to make it active. 3. Make sure that Edit >> Selection Filter >> Enable Selecting Polygons is checked. 4. Click on the powerplane to select it, then just hit your 'delete' key on the keyboard.
