I was hoping you could tell me where to find some articles for the Autodesk best practices. We are having problems running cad on our network because it is slow. The network is ok other applications work well just not Cad. The problem is latency though we have them on a gigabit connection and some of these drawing are not very large. I do not know that much about cad but I know that the x references are really slowing them down. Sometimes there will be as few as 4 or 5 of them and it is still really slow. If the xrefs were large I can see why it would be a problem but they are less then 6 meg or so. The Cad users are getting out of memory errors as well but not when then work from home. Are there some settings or group policy changes that can be made to increase performance? I know that we have CIP off but I don't know what else can be done. Any help you can give me would be great. We are running Cad 2009 and cad Civil 2009 on XP professional. The Cad users all have computers with more then 3 gig of Ram and they are all Dual processors at 3+ giga hertz.
