Hi all, 
I want to show a simple way.
 
For example a 2D Drawing (DWG or DXF): 
- Save as PDF file. ( PDF Creator - OpenSource) 
- Drag and drop in INKSCAPE -> RMB -> Ungroup objects 
- Export to *.eps 
- Open/import -> Moi3D and now all the "lines/curves" can be direct selected and extruded....
 
It`s also possible to trace images/pictures with INKSCAPE and save as *.eps.
 
1. Screenshot -> *.gif file 
2. Screenshot ->*.gif file within INKSCAPE 
3. Screenshot -> Tracing and save as *.eps 
4. Screenshot -> Open/import MOI3D
