Top-Level Assembly State Bug?

nickolas_koenickolas_koe Member Posts: 2 EDU
I have a top-level assembly composed of multiple subassemblies - on first load the assembly appears correctly, but moving to another tab and then back to the main assembly causes it to display what seems like an older version. Moving individual parts around after suppressing their mates updates them and puts them in the correct position, and refreshing onshape shows the correct assembly.

    We have been seeing this issue and are working to address it. The current, stable workaround is to clear your local display cache and clear your browser cache

    I've been experiencing it too recently. Sometimes many parts are missing as well.
    ctrl+f5 seems to help

    I have recently seen this as well I think about three times since update before last.  I happened in a way where I was left feeling like I new what was happening but could actually put my finger on it.  It was sort of surreal.  I didn't feel confident enough I hadn't imagined it so I didn't report it.  For me, refreshing my browser put things right.

    For me it isn't a previous version I'm seeing.
    Rather it's just parts disappearing.

    I was diving in from assembly to assembly to look at a part. When I pressed the back button to go back up the assembly most of the parts are gone.


    OfCourse F5 fixes it, but this is happening very frequently now since last update at least.

    I mean, so frequently I just happened again on a similar assembly
    this time I didn't press the back button, but just opened the assembly tab from the tab manager

    I am having the same issue, when I switch back to the assembly from a part studio, a lot of parts are hidden. they are set to show in the tree but if you toggle the eye icon they come back

    Solution, Press Ctrl R , refresh browser and everything is back to normal.

    yes, that works, but you should not have to constantly do that every time you go to the assembly while working on it.

    I hope somebody has created a support ticket?

    John. Please refresh me on what ctrl+f5 means. Can't find ref in help files or short cuts.
    Saw some problems the other day that fit with Nick's description. Wasn't just in one assembly, but the whole document.

    it will force your browser to retrieve data from the server rather than from the cache.

    I filed a bug report for this and linked back to this forum post.

    Now the problem seems a bit less frequent, and I get this notification when it occurs (and updates after a part figures itself out):

    Another workaround that might be a bit faster than a full refresh is to right-click > hide all instances, right click > show all instances.

    I just changed some holes in a part studio and when I went to the assembly nothing had changed and some parts were hidden. I hid all the parts and showed them again and all the holes then corrected to the new position. It might be related, I will see what happens. :-)

    To clear local display cache, press Ctrl+D (twice on Windows), then click the button near the bottom.

    I would but in this case, it seems like a problem that will require me to input a lot of time attempting to showcase it in a way that support feels confident they can bug it.  :).  There is no way I can think of to demonstrate it because as soon as the document gets opened, the issue disappears.
  • NeilCookeNeilCooke Moderator, Onshape Employees Posts: 4,228
    Thanks @shawn_crocker we have found some examples and are working on it.

    Sorry @NeilCooke.  Just being honest.  
  • Ben_Tek_PacBen_Tek_Pac Member Posts: 40 PRO
    I have found that it also is causing an issue with measuring in the assembly. I was not able to measure from some parts and when I hid all parts and then showed all parts the measure toll works again.
  • shawn_crockershawn_crocker Member, OS Professional Posts: 423 PRO
    I happened to me just now and I was able to show it.  I made changes to a sub assembly.  The top level assembly is referencing the workspace.  The top level assembly is still showing the old version of the sub assembly until I refresh.

    We just pushed a fix for this. Please let us know if you still experience the problem
  • john_mcclaryjohn_mcclary Member, Developers Posts: 3,634 PRO
    Thanks @Matt_Lo
    I love you all at Onshape Support. I'll let you know if I see it again. So far, I haven't seen it in a while.  (Ever since I submitted a ticket, of course! Call the mechanic and the car runs like a million bucks...) :smile:

    Glad you had enough information to isolate a potential cause.
  • shawn_crockershawn_crocker Member, OS Professional Posts: 423 PRO
    I am amazed at how fast fixes for stuff like this come to fruition.

    Thanks @shawn_crocker - considering it took us 4 days to find some examples and reproduce it and then less than 24h to fix, QA and ship it, shows the dedication and expertise of the Dev and QA teams. What amazes me is that there is always someone who knows the cause and knows how to fix it!
