I often use appearances in my models, to make it easier to differentiate between the parts in th assembly, but it also makes it look better, when showing images to the customer.
But now I am experiencing something strange:
When I open the assembly everything seems fine. But sometimes, after doing a rebuild, all appearances disappear, leaving me with a gray mesh of parts.
When I close the model and opens it again, everything is back to normal. Until it happens again.
I attached an image to show what I mean.
Can someone help me?
On a couple of those parts shown there is a grey appearance set in assembly level but I can't tell if it is a assembly you inserted into the assembly you are using. Right click on your top level assembly and make sure you haven't set a gray color for your entire assembly somehow. Since you are setting all appearance at part level you can remove any set in assembly level. All assembly level appearances will override your part level ones in hierarchy.
Cheers,
