I have a multi-configuration part that repeats in an assembly. It has no errors in any configuration. All bodies are visible in all configurations when the part is open. Right-clicking the bodies in the assembly shows them to be visible. They are also visible in the subassemblies. I feel this might be inconvenient for the people who will be trying to identify and assemble the invisible components, so I would welcome any insights.
Welcome to the forum. It's going to be difficult to help without more information, but I'll give it a shot. First of all, the title of the discussion refers to a part in an assembly but the text seems to imply that it's a single body of a multi-body that isn't showing. Which is it? and the first thing to check would be to make sure there aren't any upper level over-rides hiding the part or body.
