Problem with opaque view, with one active component.

[Anonymous]

Hi all.
I started to experience a preview problem.
If I have the assembly active, at the top level, everything is opaque and fine.
When I activate a single component, the other components became clear shadows and the component selected in opaque, and that's fine too.
But what happens to me is that I activate one component, others become shadows and others remain opaque.
The problem is that all the other components should become shadow when I select a single component and that is not happening.
Can someone help me?
I upload videos with the problem.

First check if your setting for active component visibility somehow got turned "on". The top box in this image should not contain a check mark.

The second thing I would check is if you somehow have copies of other bodies in those components. Using the browser controls you can check a few things. 

You can isolate a component by right mouse click > Isolate. This turns off visibility of all other components. Do you see more geometry than you expect for that isolated component? Check the bodies folder for that component. Are there the right number of bodies, or is the body that is there the right shape?

Let me know what you find.

Dear Phil, 

Thank for your answer. 

I am attaching some screen captures. 

First:

If I deactivate the first "Active component visibility" checkbox, I will not see the unselected component in shadow mode.
Anyway. there are no changes if I activate or deactivate this check box. it is something strange, right?

Second:

There are no copies of the bodies in the components.

Third, if I isolate the component, I see what I expect.

Finally,

Yes, I see the right qty of bodies and the shape is OK.

Thank you for your help.

Best regards.

Hi,

Sorry for taking so long to get back to you on this issue.

If you can share the design with me that would be great. I need to look at it in person at this point. If you don't want  to publicly post it, I can contact you privately. Thanks for your help.

Regards,

Hi Phil, yes no problem,
I will share the design to Phil.E
Thank for your help and have a great 2019!

Found the issue.

The components you have here are both using ABS plastic as a physical material. This gives them the ABS appearance. For some reason ABS physical material does not become completely transparent when components using it are not active, and it should.

Try adding an Appearance material to the components, such as "plastic matte white", they will behave as expected.

Thanks for posting and sharing the project! Let me know if you have more questions.

(edit: this is a bug and is reported as such, thanks for pointing it out. I can't say when this will get any attention or fixing.)

The bug is still there, unfortunately. Still needs to be fixed (very annoying if you have to redo all the appearances of components and bodies after you've fine-tuned them). Just commenting in order to bump this issue so it isn't forgotten (though I'd still much rather they finally fix all the history marker bugs, lol).

[Phil.E]

Can you give a specific example? I only found problems with one material, ABS.

You might not know this, but if you drag a color swatch on top of another swatch in the Appearance dialog, using the swatches show in the "in this design" section, it replaces that appearance throughout the entire model. So if you have many parts with ABS appearance, you can replace them all at once with one action. Physical material remains as ABS and appearance material becomes something other than raw ABS plastic.

Please let me know if this is happening for more than just ABS.

I hate to bring up an older solved post but I found this same behavior with an appearance application.

It seemed to be restricted to this one color that I can find but Fusion online is messed up today so I can't test more.

appearance is-Plastic Translucent matte (blue)

I would guess that other translucent appearance have similar issue

so are you just not going to fix this issue?

[Phil.E]

I think you meant to respond to me.

The issue is being looked at. Thanks for your patience and please let us know if the workaround fails.
