Colours not diplayed correctly in e-drawings

When I have assemblies with many parts (15 to 50) I like toasign a colour to each part at the part level to make things a biteasier to identify in the assembly. When I save the assembly as ane-drawing (2009) some of the parts will have lost their colour onsome of the faces and are the standard light grey. I have beenusing e-drawings for10 years, and this is the first time I haveseen this happen. Is anyone else experiencing this?---BrianSolidworksEdrawings
