Max problem with imported CAD linework. Max really bogs.

[danb4026]

After I import linework (highrise, single elevation for example) into Max 2012, everthing really slows down. If I move the linework, it bogs. If I select the linework, it bogs.

 

Is this a problem with simply working with splines in the viewport or is it related to something having to do with the import?

 

PS....even worse, sometimes it just doesn't bog down, it crashes.

max has a hard time dealing with too many 2D objects, you might want to slim down the imported file, delete whatever you don't need.

Ihab, thanks. I have already trimmed down all the unnecessary linework. Once I convert spline elements into poly's or do an extrude, it starts to work fine. But up until I get all linework converted, its a real drag.

ya strip out what you don't need for modeling.

then import it in .

save as max.

open a blank file.

xref it in .

will save a lot on the slogishness of the file.

Sometimes round objects are not arcs but polylines. You should watch out for those because it may slow the system down considerably. Please see the attached example:

Can you try with the Direct X display mode and tell us if things improved? The default Nitrous display driver may be the cause here. Try it we will find out!
