3D problems - 3d faces and screwthreads

[ahodder]

I am a student from the UK who is trying to draw my ideas in 3D. I am using autoCAD 2006 (just the 30 day trial) and cant work out a couple of problems:

1) How to you create hole in 3d faces, as some of my solids have holes going through them, but the 3d face on that surface covers them completely

2) Is it possible to draw screwthreads in 3D. If so, how?

Hello Ahodder !

Thanks, but I also need to know how to draw the actual thread.

Sorry, I sent you in wrong direction.
You can not create the 3D thread directly in AutoCAD.
Use a Lisp routine to draw a "thread-like" surface.
The hardest job is to construct it as solid. Also you will need a Lisp and the file will be much larger in size.
Other way: draw it in other programs (Mr T -any suggestion? :D ) and import it in AutoCAD.
I am afraid that this is not a way for beginners :(
