Hi, I am a BIM Coordinator and work with Revit every day, but AutoCAD has me pulling out my hair and beating my head against my keyboard because it takes so long to do the most mundane tasks! I have a "super" computer with 32GB (yes 32GB) of RAM, a large SSHD, with twin xeon E5-2650 processors (so it’s NOT a hardware issue). But when I open a 10MB (yes only 10MB!) CAD file (.dwg) from one of my cross company co-workers and I simply try to rotate it in 3D view, or try to explode everything it seizes up (or just spins my little mouse curser for like 10 min! seriously) What gives!?!? I’ve had Autodesk support on the line many times and they are always like sign out of the on-line thing and turn on your hardware accelerator. Seriously?? That’s all you got? Like I didn’t think of that? Come on, I know there is an AutoCAD genius out there that knows WTF is up with this crap. I read somewhere that the command exporttoautocad and aectoacad commands dumps a lot of BS out of the files and that helped a little, but what I need is a major AUTOCAD enema! PLEASE PLEASE PLEASE HELP!! I beg you! P.S. AUTOCAD you suck!!
Solved! Go to Solution.
I tried to attache the 2007 format...but I got the error message:
Please correct the highlighted errors and try again.
Whenever I run into this problem from co-workers it is because they made a hatch detail at an infinately small scale which is holding about 1000000 lines in it. Even if you have an amazing computer autocad hatches had hold millions of lines in a single hatch, no matter the size.
I would suggest opening your drawing, typing in "hpmaxlines" into the command line, changing the default to 1000 saving the drawing, shut down autocad, restart it and open the drawing. You will have to fix your hatches to be scaled to new sizes and they may not look as good, but you should use as small of a "hpmaxlines" as possible to get through with descent looking drawings. Hope that works.
10MB is very large for a cad file. We have some 2 mile long road projects with surfaces approaching this file size and we've found that the profile view really causes hangups with performance... there maybe other things that degrade performance also. What is the content of the drawing thats pushing you to 10mb would be my first question.
