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

Try to explode the imported geometry to simple entities. Is the 3D object really a surface? See also:http://www.cadforum.cz/cadforum_en/how-to-project-geometry-to-any-3d-surface-tip7297

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: PROJECTGEOMETRYSurfaceAutoTrim = 0Select curves, points to be projected or [PROjection direction]: 1 foundSelect curves, points to be projected or [PROjection direction]:Select a solid, surface, or region for the target of the projection:Specify the projection direction [View/Ucs/Points] <View>:0 object(s) projected successfully.
