Hi Pilou, if I remember right, SimLab only reads Rhino display mesh information from 3DM files, it does not read in the real NURBS objects.

So that means it won't be able to load 3DM files saved from MoI (or Rhino either if they were never shaded in Rhino or saved with "Save small").

Hopefully in the future they might improve their 3DM importer but for now you have to use some other format for transfer into Simlab composer.
