I can't change any appearance

[mark]

I have read the half-dozen posts with the same title as mine but none of them apply to my problem. 

When I apply a material the appearance changes but when I close the dialog the old appearance comes back.  When I use the appearance dialog it is worse.  Nothing changes at all when I drag the color over.  I have this problem on both projects I'm working on.  I haven't use F360 in a while so I don't know when the problem started.  Some details ...

1) The view is set to shaded with edges.

2) I've tried selecting the component before and after opening the dialog.

3) The problem happens with both components and bodies.

4) I tried duplicating a material and editing its color.  That material didn't work either.

5) I've tried with and without appearance overide in settings.

See the enclosed project.

Do you have component colour cycling enabled? What happens if you press Shift+N

hmm... it seems to work OK for me.  Am I doing something different than you are?

Yes, you dragged from the bottom of the dialog and I've been trying to drag from the top.  I just checked and the bottom is working for me but the top doesn't.  I can live with this for now but it is a bit of a pain.

I don't think it has anything to do with where the appearance is applied from.  I think it instead is the appearances in this design.  These look like appearances from an imported design, and they are all mapped to the same yellow color.  If you edit the color they start working again.  

Do you have the original imported data file for this?  I'd like to see if I can reproduce this behavior, as it is clearly unintended.

Yes, I edited one and it worked and now strangely they all seem to work.

I imported many things like the fans, motor, etc.  But the simple blocks are all original and they are what I was trying to change.  I didn't mess with the imported things.  I suspect there really is some appearance bug in F360.

I have another project with the same problem.  I can't share that one though.  Hopefully I can get that working as easily.  If not I'm in big trouble.  I need to release a rendering tomorrow.

Thanks for the good, fast support.

Not sure I would call it a "bug" but perhaps missing functionality.

I see this often with imported files.  In the other CAD softwares I use there is an option to Clear or Strip appearance Overrides from the import.  I thought I have seen this option somewhere in Fusion, but I could be confused.

the reason why I suspect imported colors are the color names here:

that naming convention of "Opaque(R,G,B)" is what we use for the colors of imported geometry.  Some formats, such as STEP, support just basic colors, and this is what those colors look like.  For instance, here is a STEP file, exported from Fusion, and re-imported.  The blocks were originally created with native Fusion appearances, but on export/reimport, they have the same "Opaque" names.

So, even though you may not have imported much geometry, I feel pretty sure that the colors have been imported

follow-up:  in the process of testing this simple case, I was able to reproduce the bug - just a round-trip through STEP reproduces it.  Created FUS-91933 to track it.

Wow.  I was right about there being a bug.  I'm not right very often.

So there is a workaround.  Just avoid opaque colors.  How do you delete colors from the dialog?  I've always hated that there are a ton of duplicate colors.  I've had projects where there was a really long list of colors and half were the same.
