Assembly/Part Appearance Relationship

[kelli]

I have an assembly of a valve assembly that is placed into a top level assembly. In the assembly, you can see the faces that have an aluminum/silver appearance. When it's placed into the top level, the part level appearances are removed.

I've double checked all of the representations (they are all lined up properly and are associative), there are no appearance overrides on the top level. There are iParts in the model as well as derived parts (based on company workflow). I ensured that all of the parts have been updated and all ipart files have been generated. This happened all of a sudden. Previously the model was appearing correctly. I have already made the drawings associated with these models, so replacing them with new instances is out of the question. Oddly enough, when i place a new instance in out of curiosity, the new instance appears correctly.

Anyone know what's going on? 

Also, these are company models so unfortunately I cannot share them. and without intentionally sabotaging one of the checks listed above, I can't readily recreate this issue. 

I'm running Inventor 2022 on Windows 10.

@johnsonshiue I think this belongs in the Inventor Forum. Sounds like an appearances bug .

Agreed, I accidentally clicked on the wrong option in the drop down when making this post. Not sure how to edit it. Regardless, I found the "solution".

It does seem to be a bug. I had an assembly feature to manually create a cross section for making a custom, non-orthographic drawing view for labeling for documentation figures. That assembly feature broke the part level appearances for whatever reason. The feature was in a separate model state and should have no affect on the appearances of the model itself. Even though it was suppressed, i had to delete the feature completely to restore the appearances.

No reason to have all of these options for representations, model states, and assembly features, if they can't play nicely together. This top level assembly model is used for making figures, doing FEA, making specification drawings, etc. If I can't keep all of these different model configurations in the same place without breaking something, then get rid of the capabilities.
