Performance with Solidworks??
Performance with Solidworks??
(OP)
Can anyone help me out??
I just started working for a company where an engineer is using Solidworks. This is my first time supporting this program, so I don't know too much about it. What I do know is for the longest time, he was using SolidWorks 2001 SP3.0 on an older Compaq Deskpro which used to run slow for him. Last week, we upgraded him to a Compaq Evo D300v which is a Pentium 4 1.7GHz with 640MB Ram.....we were all sure this would fix his problem, but he is still having performance issues. It is not the graphics card, because I have checked the compatibility with solidworks and I have the latest drivers(3DLabs Oxygen VX1). He is also running on Windows XP.....I do not know what else to try at this point.......he showed me an example of what was happening....even on a part with only 50 components, he goes to do a rebuild, and it takes minutes, usually slow enough to not allow him to work on anything else......Does the processor really get that hammered with simple requests, or could it be memory?? Any help would be greatly appreciated......thank you

I would have to question the types of models he has in his assemblies. Does he have a lot of in-contexted features or mates? Does he have a lot of Helix-based parts (springs and such) in his models? All of these can be great resource hogs. Also, try going into:
Tools>Options>System Options>Display Selection and make sure "Edges displayed in shaded mode" is set to "no edges".
Tools>Options>System Options>Performance and make sure "Assemblies" is set to Remove detail during zoom/pan/rotate.
Also go into Windows Control Panel, and under Display, make sure the options for Hardware Acceleration is set to full. Conversely, if this might be a video problem, you could try to set your Software Acceleration to full instead, and let SW do all the work. Not sure what's available for XP.

Just to make sure we're all on the same page...
Is he having the problem in the 3D Assembly file(i.e. blahblah.SLDASM), or is he held up by the 2D drawing(i.e. blahblah.SLDDRW) of that Assembly. If he's in the 2D, there's nothing I know of that works well. Rebuild there in my 2D drawings usually takes anywhere from 2 to maybe 10+ times longer. Don't waste your time with the Rapid Draft either, it's more nuisance than it's worth. From what I've heard, the problem here is that it takes more math calculations to generate all of the edges\lines than it does to generate surfaces/solids and their intersections.
Sorry I don't have anything else to add for a 3D Assembly file. We had some issues with imported parts slowing everything down, but SP3 fixed that.

First, I should have mentioned that there is an option in NAV to disable the realtime protection for testing the scenario (at least there is in the coporate edition). Uninstalling virus software can turn around and bite you in the rear.
I am not sure if it would cause a performance issue, but during the installation, there is an option to provide SW with performance feedback. I am not sure how it works or if it is even an issue, but I have never enabled that option.
Is this PC connected to a network? Are the SW files on the network or on the local machine? How fast is the network card and switch? I know there is a slight improvememnt in opening/rebuilding models from the local HD versus a network drive, but I did not notice any difference when we switched from a 10mb to 100mb network cards.
If you want, I would me willing to test out a couple of scenarios on my machine. Just zip up the files and send them my way. Not sure if it will really help solve your problem, but may identify whether the performance is typicaly on different systems.

Have you tweaked the XP OS at all? Without running SW, check task mgr and see what types of applications/services are running. Are any of them taking up a ton of memory or processor time? I can't imagine that this would make a huge difference, but some installed programs run services that are not required by the system. In my NT and 2KPro systems, I have removed several applications that were eating up resources.
I am not sure if SolidWorks utilizes virtual memory, but you may want to try increasing the maximum and default sizes. I have done this because I run large FEA problems, so I'm not real sure if it would have an impact on the performance of SW.
Have you discussed this with your SW reseller?
BTW, how complex are these models?

RE: Performance with Solidworks??
Right now I am working on an assembly with 723 parts, Rebuilds take a good 20 seconds, while a Save will take closer to a minute. I'm working with Dual 1.7ghz, Win2K SP2, SW01 SP1.2, 1gb memory, 64mb GLoria III video card. SolidWorks doesn't take advantage of the twin-procesors, but it helps for multitasking.
Networking issues may be causing the problem like DSI memtioned. At work, we noticed a huge improvement from reconfiguring our engineering half of the network to be on our own switch and 100mb.
There is a free program called UnFrag, works wonders with SW files to help reduce size and might help. You can find it with a quick search.

RE: Performance with Solidworks??
1) You are slow when rebuilding the assembly right?
2) Does this machine load/save the assembly slow?
3) When NO file is open in SW (just SW), if you click on Tools|Performance is "Use Software OPenGL" checked, unchecked, or grayed out? With the Oxygen card, it should be unchecked. If grayed out, you need to fix that problem driver-wise since the PC doesn't know the card Can do OpenGL.
4) Where is his temp file pointing?
5) Was Norton running when you "Installed" SW?
6) Is his Paging File size much larger than his 640mb or RAM?
I'm trying to break mine for you, but my 900 parts continue to be as "zippy" as before.

O'kay, try this. Goto sw document properties, and then under image quality. Is the "shade quality" set at default? custom? If custom, is it at the highest possible quality? If yes CRANK IT DOWN a little bit, but do not set it too low! When you turn down your image quality down, it seems to effect only 2-D drawings (screen view), you'll see blown line segments/tangent/hidden attributes that you probably don't want to see in your drawings. Adjust "wire frame quality " also. Hope this helps.
RE: Performance with Solidworks??
As a suggestion is Auto-backup checked? What maybe happening is when when he is saving or just doing normal things and it starts slowing down it, there may be a backup taking place. I have seen this max out the CPU. The fix for that is to just turn it off and save more frequently.
Also, if there any errors at any stage (part, assembly, drawing) you will significant slow downs.
Couple of Quesitons from me to you:
Are there any DT (Design Tables) being used?
Lots of Configurations possibly without the use of a DT?
MadMango pointed out the Unfrag utility which I used to use it. I now use Eco Squeeze
http://www.ecocom.com/eng/index00.htm
Works the same way but with nicer options. It remembers the last place you used it and you can remove the Shade file SW creates when you save the file. (Shade file is the image of the file, that is used in the preview of it). Plus some other options.

RE: Performance with Solidworks??
One question that may have been answered already above....Are the files local or on the network?
BBJT CSWP
RE: Performance with Solidworks??
The reason? If he has his system saving Edrawing info AND updating Mass Properties on save, that would casue some slow down for sure. I haven't tried to set my system to do that and have it autosave also. So, I don't know if autosave would save M.P. and EDraw info too....
What do you think?

Since you've tried everything logical, here's a few more straws to grab at:
1. Try booting up without connecting to your network. Maybe something is going on in background.
2. Ask the VAR that sold you SolidWorks for help. Burn a CD and let them show you how the files run on their system.
Also ask them to take a look at your system and SolidWorks setup.
3. Ask Compaq for help.
4. Uninstall SolidWorks and Reinstall.
Please let us know if you solve this problem.
RE: Performance with Solidworks??
Delete the C:/Windows/Prefetch/ files each time you start the computer. Its a WXP thing.
Disable you virus checker after you start the sytem and check your email. Clear out the temp files. Do not switch around when using Sworks.

Note: This is not the answer for your future, but may help debug the problem.
If there IS a significant difference, look for features with no relationship to part datum planes, and inconsistencies in sketch relations/converted edges.

RE: Performance with Solidworks??
This problem was not on SW2001+, on seen now on 2003.
Solidworks support have no answer as yet, and neither have I, when I do I will post it.
One temp way round the problem is parasolid the assembly. the fallback being you lose your tree.
Good Luck
RE: Performance with Solidworks??
In XP. Settings - Control Panel - System - Advanced - Performance (visual effects, blah, blah ......). Turn OFF everything! - except maybe the last one which gives it the XP/Disney look rather than like Win 2000 and does not seem to be a problem.
Here's an example of why. You don't want your CPU constantly calculating such putridly mundane and worthless things as shadows for your mouse cursor!!!!
You will be amazed at the speed increase in everything. (However it may not entirely solve your problem but certainly did for us using SmarTeam PDM with Solidworks).
BTW: I do have an issue with Compaq. At the Las Vegas SW World Compaq provided brand new "state of the art" systems for the presentations. NONE of them would even read my CDROM of my presentation. Yet every other system I have tried it in, including two at home read it fine. We had to send it via my laptop through the internet!!! Now you may say I'm being unfair, but we tried HP's some time ago and they were slower than molasses. Why can't these "big names" just leave things standard instead of "customizing" the hardware, OS and stuff?!
A couple of other things - are you using any SpaceBalls or similar 3D pointing devices?
Do you ahve Lotus #$%^!!@ Notes running in background or anything else for that matter?
Lastly, there are graphics board issues even with apparently "approved" boards. You need to look carefully at the approval date and version of SW at that time. Sounds like it would pay you to buy a cheapy just to see if things change at all.
Also remember that to completely turn off software open GL, you may need to address it in both the graphics driver
for your board and in SolidWorks PLUS setting the slider bar to zero. On some early versions of SW, I seem to recall you had to reinstall SW to turn it off, but my memory may be bad there.
