Thanks. It has been discussed here also. The guy that made it did actually work on a node addon to Moi but he abandoned it probably in favor of Plasticity. But I actually forgot to check if Plasticity can import and export sat/igs/stp-files and it can.

I didn't have much luck with it though. I could only get the igs-format to work and Plasticity couldn't fillet the model properly. Actually it was worse than Viacad. But if you can get it to work I will put it up by the rest ;-).
