Recurring crash and slow assembly and drawing (SW2016)

Other sections CAD Materials

Hello, I'm coming to you because we have more and more problems with crashes and slowness on SW 2016.

Ex Crash:

-Creation of cut

-Export drawing in PDF

-Simple window change between assembly and drawing

-Various other totally harmless manipulations!

The problem is that these crashes are not systematic (not related to a particular action or to a particular assembly or drawing) and therefore the cause is no less complicated to identify.

This happens mostly on the drawings, our pet peeve on SW!

To put a little context:

-System info:

i7-4790 3.6GHZ processor

16GB of ram

Graphics card K2200

Network work (I don't know the characteristics of the network!) however some crashes could be reproduced locally.

 

-SW 2016 sp4

Assemblies of up to 5/6000 components

Drawing (dimensional) assembly of less than 800 components

Drawing (for export) of the largest assemblies

 

For example, some users had more than 20 crashes in a day, for our design office of about 15 cartoonists the lost tps quickly becomes representative!

These crashes seem to have come since the famous 2015 version and its batch of "incompatible" Windows updates without being able to confirm it.

 

I'm drying up on the possible causes.

Our PC configuration seems okay to me, maybe the graphics card a little lite for our larger builds. I was thinking of eventually switching to a workstation (a real one!), to test if there was a gain in reliability.

Our network seems to be working fine (I don't have any more technical info on it)

Maybe our way of designing is completely crazy...

I am currently working on simplifying our models in terms of file size, number of bodies, removal of surface area if existing in order to lighten them as much as possible while keeping a sufficient level of detail for our designs.

In short, I'm a bit lost and looking for answers, leads, suggestions, information or others!

Thank you.

I'm thinking of a conflict between windows and Sw.

 

Know which one..... So the...

 

I know that there are Windows updates that are not compatible with Sw, the other members will be able to tell you which ones.

Hello

Show the update to SP5 and check if it still does. The problem is on all your post and does it have the same version of Solidworks and Windows update???

Have you ever tried to do a cleanup with ccleaner and then a system cleanup and a defragmentation to put everything back in order???

Hello

For my part, I think of a somewhat borderline configuration for such large ensembles. You should look in the cases of crashes if the use of the PC is not at the maximum (RAM and proc), if so you have to look there. In the settings, do you have double the RAM in virtual memory?

Otherwise, to guide you, why not contact your dealer who will be able to help you find the problem (more likely to do so and offer you a solution).

I just updated to Sp5, I'll try to reproduce all that.

Ac cobra@ we don't all have the same configues but we are all on the same SP (I'm the one who manages that!). The positions concerned are almost identical to mine.

As for the PC maintenance I try to keep it "clean" (ccleaner, defrag, SW RX etc) for my colleagues it's something else!

Cyril.F@ I don't have any particular problems with the RAM (half use at most), some peaks in CPU usage, maybe our pross a little light... I'm not sure that increasing the virtual RAM would solve these problems, but I can test!

Some crashes occurred by the simple fact of dimensioning or adding a marker bubble on an overall shot and not only by a loading that would consume PC resources that would end up "flashing".

I approached our dealer before but am looking for other leads!

Thank you for your answers

Hello

Maybe a lead, do a ctrl+alt+del and see if you have a task called "svchost" that could eat up your cpu and memory. If you have problems with "svchost" here is a link that might help you:

To go in the direction of @Bart. If after updating your software to SP5 the problem is still not resolved, it may be good to uninstall and re-install Solidworks (don't forget to get the license key if you do)

This is because there may be installation errors or conflicts between the system and the software.

 

Also remember to check the status of your integrated steps. A little surface in it and slowness shows up. A bit of a "construction error" and he has trouble calculating everything. In this case, try as much as possible to right-click and "diagnose" it to repair the part.

 

That said, it is still starting to get crowded in your blends. It seems to me that the slowness will be inevitable

Once my parts are finished, I lower the blocking bar to avoid unnecessary reconstructions. It avoids slowness in assembly and MEPs that rebuild at the slightest opportunity. Try to see this...

The problem is not so much the slowness on the assemblies, the PC is rather responsive even on large assemblies with surface, greedy parts (like spring) etc. On the assemblies it's mostly an unexplained crash problem (no exessive use of the Ram or CPU).

The biggest problem comes from the drawings for an assembly of 800 components, about 5MB for example

As soon as I make a dozen views, most of which are cross-sectional, even if the already finished ones are hidden, the drawing remains "uneatable". More than 30 seconds to create a cut, 5 seconds to zoom out or put a note, in short it's a long time! Not to mention the crashes!

We didn't have these problems before moving on to 2016, but since then I've cleaned up all our models, tried to optimize the options for performance as best I could. I discovered the blocking bar recently, it seems interesting but only applies to single-body parts it seems to me so can be used here.

I still have some tests to do with the SP5 but from everything I see it seems to come more from a SW / Windows update problem.

Depending on the history of your machines (successive SW installs), it might be interesting to build a blank machine (formatting, clean installation of windows and SW).

It takes time and/or you have to have a machine available.

The problem being on the drawings, have you tried to switch to draft quality if not already done on your drawings to see if it changes anything

stefbeno @ A good old formatting, it should be planned in our schedules! Of course it wouldn't hurt, after that it's very time-consuming but for an undeniable gain I have to say 2 words to my manager!

Vspemens @ The draft-quality drawings do not allow us to make pdf prints (very poor quality) and sometimes bug during the DWG export, these 2 formats serving us as a distribution to our customers is a problem! And I don't remember it being faster or more stable.

I compile the information of each one:

After a few tries following an update to SP5, it seems to come from a SW/Windows conflict and/or Solidworks service pack.

For various problems, the update to the last SP is essential.

A methodology for managing large assemblies should be applied to lighten them in order to limit the resources required and crashes.

In case of major problems, a reinstall or even format PC can be considered.
