Hi Michael,

first of all, thanks for your answer.

I tried to export a 3DM from solidThinking but the result is bad, I purchased MoI v1 to access the Beta 2 and with the STEP file the result is great, but is still not perfect in some areas.

I attached a movie so you can see the problem (try to scrub forward and backward to see the problem).

Is the "STEP" file a better format for convert Nurbs to polygonal or is better to use the 3DM file format?

If I export an IGES from solidThinking and I open it with MoI I can't join the surface, is this a problem of the IGES?

I also attached the model in 3DM, STEP and IGES

Thanks
