Hi Randy - hmm one issue that I forgot about is that Rhino may tend to make block instances out of stuff it reads in from STEP files.

MoI doesn't read in blocks, so if that was the problem try running the "Explode" command in Rhino before saving, that will convert any blocks into just regular geometry that MoI should then be able to see.

You can see what type of object it is in Rhino by selecting something and running the "What" command, and if it says that it's a block instance then it needs to be exploded.

Yeah if you don't actually see the colors in Rhino then they didn't come into Rhino either - you would probably normally see them as layer assignments with the layer colors set up.

It could even be possible that Pro/E does not write out color information to the STEP file in the first place.
