iges e step in rhinoceros

[uelucio]

Good morning to all
I started using rhinoceros 5
when amount iges files and step lose all
icolor of surfaces
I don't have a problem when I work in
mold industry and how you will know the colors identify
the processing grade of the surface itself
I don't know and I have to change.
I hope someone helps me
thanks to all of us

As for the step, it is a matter of the "ap" with which it was exported, the "ap214" also exports colors.
