Can you import igs files?

[Fonte Boa]

Since Wings isnt able to read IGES files, either DWG, maybe you can try to find a way to convert you igs to STL format and then import them (just theory, once i havent tryied it).

EDIT:
There is a free software that promises to open IGS and save them as STL: HeeksCAD.

About: https://sites.google.com/site/heekscad/Details

Maybe you could provide a 3d igs file to test if HeeksCad can convert it to STL format and if Wings can import it...
