I am able to import my 3d parts using the "File -> New -> 3D Model..." menu option and can readily resize or orienteer the part to fit etc. However I notice that all my "*.wrl" models imported are only shown as a single colour. Yet I know that you can get colour 3d parts as the standard red, blue and green LED 3D model's all have colour. Similarly capacitors and resistors show multi shades of grey etc.
So how does this work? I know if I open up my .wrl files in a CAD package I can see my different colours for different surfaces etc.
