Hello!

I'm trying to "draw" a logo from AI on a AutoCAD "wall". And I have some problems about it.
The dwg export from the Illustrator is a hatch. The wall in AutoCAD is a 3D solid. So I try PROJECTGEOMETRY. Since it works only with lines and polylines I "recreate boundary" in the hatch edit, get splines, in order to get polylines I try a lisp from the web which doesn't work, I do it manually to finally use PROJECTGEOMETRY.
It doest't work.
So I created a planar surface and a simple line to test. It didn't work neither. What might be wrong and how to do it right?

Thanks

Thanks. The link have already been my first choice to learn about draping. But:
I open a new drawing, I draw a plansurf, I draw a line, I want to project the line on the planar surface, I choose the line, enter, I coose the surface, enter, enter.
Command: PROJECTGEOMETRY
