importing DWG in 3ds max

[jasonlg3d]

I have an autocad file I need to import. It is just a 2d top view but I need it for measuring accurately. When I import it it seems to come across ok but it slows my viewport down like crazy. I deleted all the excess stuff that it has on it that I dont need but its still really slow. Below is the file summary. Is there some setting I can use that will speed this up? I have a P4 2.8 1GB ram ATI 9800pro 128MB.

Hello,

Press the "o" button on the keyboard, not the zero, the letter o, that should help...

Thanks guys. I guess my vid card doesnt really like splines. I cleaned it up and extruded it and now I get liquid smooth frame rate. I dont really understand that but oh well. Any ideas?

i use a ATI Quadro FX 1300

ATI do not make Quadro's, that's Nvidia and their IHVs. ATI makes the FireGL line.

I came across that problem with my previous Gforce FX 5950 Ultra. All imported autocad files really slowed down the views. I use an ATI fire GL 7100 now which does not really care, so the problem is off!

Clean your 2d work as much as you can, delete, text, hatches, and points, that will speed up the process, once done that convert your 2d work to editable splines, amke shure that you don't have any blocks, because max read the blocks as instances.

 

If that doesn't work, generate an AI (adobe ilustrator file) from the export menu, 3ds max can impor AI files containing 2d data, use version 4.0 or so, because Max doesn't have support for recent versions...

 

if neither of these works, can you post the file?
