Is it possible to draw polygons that are not regular?
Yes. You can do that. Many ways.
Hemet here, anyway you can help me?
I’m new to SketchUp.
Have you tried the pencil tool? You can make edges in any shape. To get specific help you will need to describe or show more specifically what you want to do.
