ReMark Posted February 19, 2014 Posted February 19, 2014 Things that may influence the speed of AutoCAD. Hardware setup File size Xrefs Working on a network Anti-virus programs CommCenter Hardware acceleration Drivers Windows Indexing Layer filters Virtual memory Paths to folders/files Digital signatures Sometimes it is just a matter of a process of elimination before one finds the cause.

tzframpton Posted February 19, 2014 Posted February 19, 2014 actually, AutoCAD is still super fast. Way faster than Revit, when talking raw performance statistics. Revit is just far more efficient in creating models, editing models and creating/editing sheets and subsequent information directly related to objects. The Revit platform itself isn't "fast" but I don't think that's what the O.P. was referring to when he mentioned speed. Quote
ReMark Posted February 19, 2014 Posted February 19, 2014 Well he did state he had been struggling for a year with poor performance. Personally I would have thrown my computer out the window after one week of sub-par performance let alone one year. The point I tried to make, which he studiously ignored, is there might be a reason why AutoCAD was slow and maybe he should have tried to figure out what the reason was. Changing to another program wouldn't guarantee him a "speedier" platform necessarily. In the meantime, until he made the switch he would still have to live with the system he's got. I wished he had told us what he did to troubleshoot his problem over that year he was struggling. Quote
tzframpton Posted February 19, 2014 Posted February 19, 2014 I disagree Mark. Read his original post: Hello after year of struggling with autocad as a 3D software and the slow performance issue i came to a conclusion that its impossible to create normal work flow when working in 3D (and im talking about a box or a pyramid) . i have the best i thought it will change the speed bu the real thing is that it doesn't matter , autocad is not a 3D software and will never be.. So now im looking for another software capable of dealing with 3D geometry for piping and accessories , in high speed. any recommendations He's clearly talking about "work flow" more than anything. He actually comments on how he "has the best" and by that I'm assuming his computer is robust enough for AutoCAD. He then mentions "it doesn't matter, AutoCAD is not a 3D software". So to me it's the non-intuitive performance that he's commenting on, not the "speed" 3D modeling. And, to be honest, he's absolutely right. You know I hate disagreeing with you Mark... but in this particular case I feel your intentions are good, but your definition of "speed" is off regarding exactly what the O.P. is inquiring about.

ReMark Posted February 19, 2014 Posted February 19, 2014 Well Tanner I disagree with you. Two words...slow performance. Read 'em and weep dude. Quote
tzframpton Posted February 19, 2014 Posted February 19, 2014 Hey, maybe it's both? So we're both right, haha. Quote
ReMark Posted February 20, 2014 Posted February 20, 2014 It would have been helpful to know just what the OP's workflow habits were. Was he making use of a 3D block library for his valves and fittings? If so, were these blocks on tool palettes? Was he using a custom template file with all required layers, dim and text styles, etc. as the basis for each new drawing or creating each from scratch? Was he making use of xrefs? Was he using the Dynamic UCS feature? Etc., etc., etc. His reluctance to even discuss the problem in detail was mind boggling. Quote

road runner Posted February 21, 2014 Posted February 21, 2014 Take the softwear off and re-load it! Quote
ReMark Posted February 21, 2014 Posted February 21, 2014 And that will fix what? The OP did not give any specifics. Quote
road runner Posted February 21, 2014 Posted February 21, 2014 We had the same problem at work (slow) the reseller told the I.T guy to take it off and reload the softwear. It fixed the problem. I'm only trying to hlep.!!!!! Quote
ReMark Posted February 21, 2014 Posted February 21, 2014 What else did you do in the way of troubleshooting BEFORE you uninstalled then reinstalled? Microsoft used to give the exact same response to users that experienced problems with Windows until it was pointed out most problems could be solved without resorting to such drastic measures. For all we know though maybe the OP already tried that option. Unfortunately he was stingy with his information. The OP's problem could simply be a matter of file sizes getting out of control (ballooning) because content was brought over from a drawing done in Microstation. In my opinion an uninstall/reinstall done without first eliminating other causes of the problem is like buying an entire new set of tires for your car because you found out one of your tires had low air pressure.

road runner Posted February 21, 2014 Posted February 21, 2014 I will ask I.T on Monday and will get the full SP on why he re-loaded the softwear. Quote
ReMark Posted February 21, 2014 Posted February 21, 2014 I.T.? Now I know why....that's always their first reaction! LoL No need to bug them. Thanks. Quote
tzframpton Posted February 21, 2014 Posted February 21, 2014 I'm with Mark. I can't see a mere reinstall being the reason behind an increase in performance. There had to be some other factor involved. Quote
ReMark Posted February 21, 2014 Posted February 21, 2014 Tanner agrees with something I said? Can't be. Must be a doppelganger. Quote
tzframpton Posted February 21, 2014 Posted February 21, 2014 awww c'mon now Mark, you know you're my favorite!! haha Quote
ReMark Posted February 21, 2014 Posted February 21, 2014 If I'm you're favorite how come I didn't get my dozen roses on Valentine's Day this year? Huh? Only kidding folks! Tanner sent me a very nice poison ivy plant. Quote
ksperopoulos Posted February 25, 2014 Posted February 25, 2014 We use AutoCad with an add-on called Autodesk Fabrication CADmep. There really are no performance issues that we run into until the file sizes start creeping into the 60+ MB range. One reason they get so big is due to the fact that the architects/engineers export the whole building out of Revit for people to use in AutoCad. When they do this, not only is it a huge file (because it's the whole building), but we have found it to also slow down performance because of the "Materials" that a Revit export brings over. Once you purge the materials out of their all the DWG files, everything runs normally. Not sure if this is the OP's problem, but I thought I would throw my 2 cents in to see if it helps. http://forums.autodesk.com/t5/Revit-MEP/Revit-Material-Definitions/td-p/3117176 Quote

Talk about a performance hit.... yikes! Quote
