Drawings really slow

Hi, just some honest feedback. Drawings load very slowly in general despite having great internet speed and a godlike PC. This is our general impression across multiple platforms, within different countries, different browsers and computers, etc. and this has been the case for the entirety of our time with Onshape. So no, this time Onshape's performance issue is not the user's fault-  it's not a matter of some super technical and obscure browser setting that only an IT PhD would know, like the other issues generally are.  

Sometimes very simple drawings even take several minutes to load. Nevermind trying to work on drawings when a collaborator is in your document at all- things will nearly grind to a halt.  Super frustrating.

    Yes, drawing are always slow for me to despite anything I try to do to speed it up. It can be very frustrating when trying to quickly get a simple drawing up. Even on versions they still seem to be very slow, to me drawing on a version should be the same speed as loading a pdf out google drive at the moment there is no comparison.

    Can you post screenshot of what you consider as simple drawing, I don't do that many drawings but all I have done load in roughly same time as opening part studio of that part.

    Many of my drawings have multiple parts (5-10) with single view of each - this was serious performance hit for Alibre and to be honest I've been very happy with Onshape drawings performance and stability (after the update last year where they got noticeable improvement on performance) 

    This took 15sec from hitting F5 to fully load (when visiting other tabs and coming back it's ready immediately), 2 sheets in total - no collaborators online.

    Drawings are always slow for me.  I have learned to make a cup of coffee :) when I work with drawings (often).  Like Dan, I have high speed fibre optic internet connection and a high end work station.

    I've run into some slow sketch times but I've noticed I'm using some slow feature scripts

    As Rami suggests - drawings should open in a 'reasonable' length of time.
    Having time to get a cup of coffee is not 'reasonable'!

     I would suggest that Pro users open a feedback ticket and share their document with support.
    Free users, please post a public link here in the forums.
    In each case, we will look at the document and determine the root cause.

    Many thanks - Philip.

    IN THE MEANTIME - want a quick, awesome, speed increase? :)

    Drawings are typically made from released parts.
    Even if the part/assembly isnt released yet, chances are there are versions that exist (or can be easily added with a single click)

    • RMB over the drawing tab.
    • Select 'Change to version' (brings up the familiar dialog)
    • Select a version (or release)
    • Drawing now does everything a lot faster.
    • When you want to jump to a newer version, RMB over the tab again and select 'Update Linked Document' (and select newer version/revision).

    BOOOOOM! :)

    @phil_thomas I'd be very happy if I could get load times like that, but linking drawings back to my older visions is not going to help me get my drawings done.

    @3d see below what I'd call a simple drawing and various load times on my average internet.

    42 second to load in the workspace.
    3 second when switching back once loaded in the workspace.
    48 second to rebuild
    15sec in the main workspace linked back a version
    59 seconds on the last version (@Phil_thomasshouldn't a version be as quick as referencing back to the version from the workspace)
    shared link opened in a new browser session 1min 47sec 
    shared link of the same drawing in pdf format and saved to google drive 7 sec's

    @brucebartlett - please open a ticket - we need to get to the bottom of this.

    I have previously not done many drawings, but I started to try to do some today and I am ready to scream!  I have been lucky to get any drawings to load at all....

    @Josh_Larsen - please open a ticket and share the document with support so that we can diagnose/fix for you!

    Hi Bruce,

    Did you raise a ticket?
  • brucebartlettbrucebartlett Member, OS Professional, Mentor, User Group Leader Posts: 2,081 PRO
    No @chrisjh777 I haven't yet, I'm waiting till I am really frustrated with a speed issue then I will. I haven't been working on many drawings lately.

    It doesn't have to be 'super slow' - you can say 'this opens slower than in SolidWorks' (please give the time to open in Solidworks from cold - ie none of the parts in RAM). We may not be able to give you a magic bullet, but we are very interested in knowing anything that we are doing that might be 'less than optimal'. 

    Just off the top of my head, here are some things that cause a drawing to be 'sluggish' (but NOT necessarily slower than SolidWorks).

    A bazillion parts.
    Parts with threads (or anything with large numbers of silhouette edges (eg heat exchangers))
    Drawings of assemblies that reference multiple documents
    Drawings of parts that contain multiple derives

    There are probably many more and desktop systems have analogs for all of these - these are NOT specific to Onshape.

    Show us what you think is slow (as a reminder, we cannot see what pro users are making unless you specifically share something with us).

    Thank you.

    Sorry Philip I have to agree with the majority here, and I have submitted tickets and gotten some very useful feedback.
    But drawings have always seemed to be a neglected thing in my opinion. 

    They have gotten a few small speed boosts since release but not quite there yet.
    Small details are fine for me, but as soon as you show hidden lines you get (not exaggerating) at least a 200% decrease in performance, or more.

    Like I've said support has helped me find some work arounds, but I was under the impression those were temporary until onshape fixed the issues.
    Eventually OS will need to really spend some resources to focus on this portion with a real passion. There are many of us that cannot convince our customers that they really don't need the drawings they are paying for.

    Assemblies are where I see the most trouble. Lou and Pete have been the two who answer the call most of the time for me, and could surely fill you in.
    I don't consider these assemblies to be that complicated, but it really puts the breaks on when it comes time to detail.

    And the trick you showed for versions may be fine for viewing, but that doesn't help us when creating/editing the drawings.

    Here is a video showing what I mean about the hidden line performance. You can see when I hover over an object then pull the mouse away I have clicked and am waiting for drawings to acknowledge I have clicked something 3 seconds ago. Sometimes you see me attempt to click the object a few times before I even get a dimension line.

    @john_mcclary @dan_engerer - ok, i spoke to support. There appear to be some additional considerations with respect to your specific drawings and these were not called out on my list above.

    In the short term, detailing a version will be the fastest performing workflow (yes this requires a manual step with each version increment - updating the version).
    In the longer term, we are very much aware of your specific circumstances and we absolutely have on our development plan specific improvements to address this issue. My apologies for not being able to give specific timelines, as you all know by now, they change all the time ('agile')

    Everyone that submitted a feedback ticket will be on the list to be notified of progress on this front. :):):)

    I follow this thread. Are there any new developments concerning the performance of drawings? We still notice many slow issues in the drawings. Onshape has a lot to improve on this.

    They have sped up a few things here and there, but I also still see the same lag when having hidden lines as before.

    Has anyone heard of any new drawing updates that are coming? Assembly drawings are still slow and freezing.

    drawing in part studio with more than 90 parts is really slow... i think need make all in one and when click it just open all conect to it or some part will load faster.
