Components loosing constraints & breaking joints

[benQNT9Q]

Hi All,

I need some help to figure out where I am going wrong in my assembly, I've tried many different ways to achieve this but having no luck.

Basically I have a "case" carcass that has 2 front & 2 rear doors on sliding hinges, this is driven by an internal assembly.

I have the joints & motions working correctly for the sliding hinges but when I create the front doors (which need to be driven parametrically from the carcass of the case) and then move them to the open position to create the rear doors & check for clearances, everything losses its joints & my sketches end up on weird planes and sometimes I get multiple bodies of the same components.

I'm guessing this could be because the profile of the doors has a projection link for the door gap to the front panel and this is getting broken when I move the doors but I cant figure another way to achieve this the way I want it.

Hopefully that makes sense and someone is able to shed some light on where I'm going wrong with my workflow.

Thanks in advance.

Is that behavior something you can demonstrate in a screencast?

I downloaded the assembly model and everything behaves normal.

Yes sure thing, I'll post that shortly.

Hi @TrippyLighting ,

Sorry for the delay, Fusion crash a few times when trying to do this video.

When running a compute all, I don't see any of the warning/error messages that appear in your screencast.

I wonder if the assembly would behave better on your side, if you deleted all the position capture features in the timeline. Those are not necessary and only slow the assembly down.

Also, I believe you should look into using as-built rigid joints in soma cases. A lot of what you create is designed in-place. Dragging it around in the viewport and capturing the position to have access to snap points and then using a regular joint is more work than necessary.

Thanks for looking into this, I will use as-built joints and see if that makes a difference.

I actually got it working correctly last night by changing the construction sketch plane to the front panel instead of the offset plane I was using under the front doors assembly.

Thanks for your help with this, I think the as-built joint workflow would certainly help.
