jernej12345 Posted October 27, 2012 Share Posted October 27, 2012 Hi, I am currently working with semi large 2D DWG drawings (30 MB) and my workflow in terrebly slow (switching layouts, plotting, model space scrolling...). My PC specs are: 1. CPU: Intel i7 2600k 2. RAM: 16 GB DDR3 RAM 3. HDD: 120 SATA3 SSD HDD 4. GPU: Quadro 4000 I also have HP 8770w with the following specs: 1. CPU: i7-3610 QM 2. RAM: 16 GB DDR3 RAM 3. HDD: 120 SATA3 SSD HDD 4. GPU: Quadro K3000M I am using Win 7, x64 and AutoCAD 2013. As I said the workflow is terrebly slow on both computers. Any suggestions what could we upgrade to speed things up? Quadro 5000/6000? RAID HDDs? Thanks! Quote Link to comment Share on other sites More sharing options...
JD Mather Posted October 27, 2012 Share Posted October 27, 2012 Hi, I am currently working with semi large 2D DWG drawings (30 MB) ... Have you broken down the project into logical sub-structures? (for example - a car as an engine sub-assembly, the engine is built from more sub-assemblies) Don't put all your eggs in one basket (file) use logical xrefs. Do you need to see everything all the time? Partial Open only that portion you are working on. If you need other layers retrieve them as needed.

ReMark Posted October 27, 2012 Share Posted October 27, 2012 Have your 30MB files been purged and audited? Are you making use of xrefs? Are you making use of layer filters? Could it be a case of bloated scalelists? Have you disabled the InfoCenter? Is hardware acceleration enabled? When you are working what other programs are running in the background? Are you working over a network? Where are your drawing files stored? Could it be that your anti-virus program is being overly aggressive and targeting certain AutoCAD files thus leading to a performance hit?

Dadgad Posted October 28, 2012 Share Posted October 28, 2012 Are you using ADAPTIVE DEGRADATION? (not sure if that affects 2D or not, but I think it does) What is your ISAVEPERCENT system variable set to? How do you have your LAYOUT REGEN OPTIONS set? If your file is that large then I would use the commandline ' -PURGE ' command (with the hyphen), RegApps first, and finish with ALL, before auditing.

[ATTACH=CONFIG]38211[/ATTACH] We are planing a hospital, size about 60.000 sqm. We have it broken down into soreys and into HVAC/plumbing/water... So it is as broken down as it can be in order to have at least some overview of the system. We use XREFs for Architecture. So in actual drawing are only our elements.

Maybe, what does this mean? 5. No 6. Yes 7. Word, Excel, Acrobat 8. Files are on a server, but it makes no difference copying them on local hard drive 9. No anti virus Quote Link to comment Share on other sites More sharing options...

ISAVPERCENT was set to 50, I changed it to 0. Makes no difference. Changed Layout regen options, makes no difference. Allready purged and audited everything. Still slow.

Dadgad Posted October 28, 2012 Share Posted October 28, 2012 It is a huge file, but it looks like your setup is pretty heavy duty. The purge that you used is the -PURGE , not the less powerful PURGE command? The regular purge command will not delete RegApps. You may find you have hundreds or more of those in your file. The reference to killing the INFO CENTER is about the fact that it is known to bog systems down, and generally make lots of things less than optimal. Here is the link for the free download, which I highly recommend installing. http://www.manusoft.com/software/freebies/misc.html On the Autodesk sit there is a free utility, I think they call it, dealing with bloated scale lists, but I believe that was a big problem in Autocad 2008, not sure if it will help you or not, can't hurt though.

jernej12345 Posted October 28, 2012 Author Share Posted October 28, 2012 I used both -Purge and Purge. Still slow. The problem is, that we are planning on going to 3D and that means 5x the load we are having now. Right now we can somehow manage, although we loose time, but with the 3D drawing is will be impossible. Would better CPU/GPU make a significat difference, or do we simply have to break our buliding into even smaller segments? Quote Link to comment Share on other sites More sharing options...
Dadgad Posted October 28, 2012 Share Posted October 28, 2012 Do you have WHIPTHREAD set to 3? Kill the INFOCENTER, you will be glad you did. Quote Link to comment Share on other sites More sharing options...
jernej12345 Posted October 28, 2012 Author Share Posted October 28, 2012 Have set WHIPTHREAD to 3, no noticable difference. Same with INFOCENTER. Quote Link to comment Share on other sites More sharing options...

Not with 3D. xref or better yet - upgrade to one of the next-generation tools built for 3D design. Quote Link to comment Share on other sites More sharing options...
samifox Posted October 28, 2012 Share Posted October 28, 2012 dadgad, the acad 2009 plus has scale list killer built in. Try googling nvidia autocad performance driver, they have designed a driver specifically for autocad, post if it has an effect. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted October 29, 2012 Share Posted October 29, 2012 Do these files have lots of Hatches and/or Objects from AutoCAD Verticals/3rd party software? Drivers are the latest from Autodesk? Monitor your task manager and see if any extra processes are running. Quote Link to comment Share on other sites More sharing options...
