How can I change the color of the shape.
I have a step file loaded with XCAF and am able to select solids and faces in local context.
if the shape is a solid I can change its material with its ascociated TPrsStd_AISPresentation
not its color, if it's a face I can't change its material nor its color with the ascociated TPrsStd_AISPresentation. Does anybody have a clue or some simple example?
