Hi everyone.

First of all, I'm a Brazilian student of Civil Engineering and work mostly as a cadist.

I've been using SU for some time now, and I came to a problem I can't solve.
I need to convert a very detailed model (around 350Mb) from SU to .3ds. Problem is, it only export the most primitive geometry. I can export it without any problem to .dwg or .dxf.

My model is a large building with lots of vegetation and repeated components.

Could you please give me some help?
