Hi Pilou,

ArtForm Pro has four modules (or rooms) you can work in.

You are currently in the first. If you go to the third module/room
you have access to ArtForm's Surface NURBS modeler were you can
import .3dm files from MoI or export from there as .iges.

The other modules are used for drawing, like in Illustrator or
for sculpting 2.5D reliefs. The fourth module is for setting up
paths for CNC machining etc.

If you want to learn sculpting 2.5D reliefs i suggest you look
at Youtube videos about JDPaint. ArtForm is the successor
of JDPaint and is compatible.

Regards
Stefan
