Trace a logo or shape or import ai file or dxf to work in 3d
Do you have a question?
Basically what we are saying is you have made a statement that contains three things that can be done in sketchup but you haven’t actually asked how to do any of them or which is better or what.
So a bit more of a question explaining exactly what you are asking would help us give you a suitable answer.
Perhaps some images or even a model to see what you are wanting to do.
Help us to help you, we are all willing, just don’t quite know what you want.
The best way: Export a DXF from Adobe Illustrator. Import the DXF into SketchUp. From there you can ungroup the shape and trace a few lines to create faces where you need them.
