Performance Issue on assemblies

Sandro Pinho May 8, 2017 3:39 PM

Hello. I have soliworks 2017 premium on my computer.

I have an assembly with about 30 parts and some in context relations.

Whenever I want to edit a sketch on a component on the assembly, or delete a part, I have to wait about 2 to 3 minutes to Soliworks to rebuild and so on and I am starting to get a bit frustated about this, because I only have some parts related to others. I have big assembly mode on, tried lightweight mode, tried to suspend rebuild on the system properties (solidworks rebuild anyways) and I think I will stop using solidworks if I dont get this solved, because it is not efficient.

MY computer specs are:

i7 6700HQ

Nvidia GTX 960M

Any help is good thanks.

Hi Sandro,
This forum has seen a lot of reports about slow performance with NVidia GeForce GTX cards. The consensus around here and across the user base is that upgrading to the very latest driver from www.geforce.com or rolling back to the previous driver is able to improve this. You will definitely want to try either or both of these (upgrading or rolling back the graphics driver) to see if it helps your situation too.

  One of my coworkers had an automatic video driver update cause this kind of problem. Rolling it back fixed it.

  Thanks for your answer. Just to clarify.. I have my drivers up to date so I will try to install the earliest version and see if I have my probem fixed. Is that right? I should say that I have the files and solidworks installation on an SSD.

    As I understand it, or at least apply it on other cards, it is neither the earliest version nor latest version, but the certified version.
    You can find the certified driver for your software at: Graphics Card Drivers | Hardware & System Requirements | SOLIDWORKS

Could you upload a snap shot of the bottom end of your feature tree?

  Hello! I can send you a snapshot for sure:
  Also tried to install the earliest drivers from NVidia and I didn't noticed any kind of improvement.
  Is this snapshot that you want, correct?

    Something I found out recently was the issue with sketches in an assembly file.. The sketches or sketch related items that are at the lower end of the feature tree controlling components within the feature tree are a huge reason for lagging models.
    
    SW rebuilds starting from the first item in the feature tree and works down to the bottom, so if any part or assembly is dependent on any of the sketches that are after the last item or assembly, this can create a circular rebuild very quickly. The items can't be rebuilt cleanly, till the sketches are rebuilt, so you need to hit ctrl Q at least twice to make sure your items are updated..
    
    Traffic light symbols in your feature tree proves that point and that is why I wanted to see the bottom end of the feature tree.. (Circled in blue.)
    
    For a better explanation see the attached

      What you are saying is that I should not use sketches to mate parts in place..
      I can´t test right now what you said because it would be very time consuming to change all and I can´t right now..
      But when I can I will give it a shot.
      However I will pay attention to that detail next time.
      Thanks

        I would use sketches etc with caution, "if" they are below the last part in the feature tree. I would suggest that you setup your assembly template with sketches already in place, prior to inserting any parts, that way they stay up top where they will rebuild before the rest of the assembly..
