Trouble with DWGs

[martin walker]

Ive imported a DWG file, after tidying it up in A-Cad. It only consists of around 10'000 lines, but its horrendously slow in the viewport. Does anyone know the reason for this ?

 

cheers in advance

Check to make sure its not too far from 0,0 in acad before you impot it.

yeah...its bang on the origin.

lines (shapes, splines etc..) are allways slower as geometry in the viewport

Is the geometry flattened - are there any z co-ordinates in the geometry?

You didnt exploded the cadd,do you?delete all the hatches also,it will help.

You can speed thing up a lot if you try linking a modified .dwg file that only has a few layers in it. I usually make two copies of the (orginal dwg) file. In one file I delete everything, and in the second file I use the paste into original coordinates command to paste in one layer at a time. It takes a little setup but it is worth the increased speed in Max. It makes Max much easier to navigate.
