Hello Alexey.
Thanks for your answer. To be more specific, my model has parts made of aluminum and painted red and gold. When
I insert the part as 3d fragment in a 3d assembly, it appears that the colors are ok, but the aluminum and the paints
doesn´t appear in the tree of the 3d assembly. There is only "Steel" in the "Materials" folder and all the 3d fragments
have only "Steel" associated.
Because of this, I don´t know if the software really is using the materials that I selected for each part. My final
objective is to run the dynamics test and calculate inertia matrix.
Please look at the files attached and compressed.
Regards.
