I downloaded some valves from 3D Content Central. They are all colors clear/ transparent. I would like to know if there is a technique to add solid colors to the part once imported? I am attaching one valve to this question in .IGES as I downloaded it.
This is a surface model
The other thing you can also do, is thicken the surface, if it is just surfaces.
I frequently run into models, especially *.iges models, with all-surface geometry. I try to specify *.step rather then *. iges whenever possible for this reason. Most of the time, if you import a file and it comes in as a surface body, it means that modeling errors are present. Models should ideally be all solid geometry, with the exception of Cable and Harness wires and segments, which are by definition surface objects.
Thanks Joseph, that is good information. I didn't realise the difference between step and iges before. I will try to do the same.
