Rhino 7 - Can't change surface color on .STP import

Hi, on Rhino 7 (7.4.21067.13001) I cannot change the surface color after importing it from a .STP file.

As you can see from the image below when I select a “Display Color” (Red) under “Properties Object” it colors only the edges and not the entire surface as expected. Am I missing something?

Thanks

Hi Julio -

Can you post or upload the STEP file?
-wim

Try running RemovePerFaceColors…

Thanks, this command did the trick
