Hi Michael,
I've noticed that MoI imports IGES but makes strange groping/merging on parts.
I make an assembly in Alibre, export STP214, convert in IGES thru iges2step and then import in MoI.
After that I use the MoI .obj export for KT or Carrara.
The import is correct but some parts are glued together and do not respect the original part assy.
I verified the IGES file with Polytrans and the file is Ok.




The selected parts are merged.
Ungroup command does not work properly (in this case) because it separates all the surfaces.
All the parts are mated/aligned in Alibre with zero tolerance.

The MoI file is too big to upload.

Any idea? I like the MoI Exports and I wish to use it to adds details and 'prepare' the scene and the Alibre parts/assy for rendering.
