Thread Starter 
im working on a small project, small enough that I didnt buy autoCAD. I'm using the 30day trial and so far i looks like everything is working to fullfill my needs. Im designing a new Rocket Motor (my hobby) but i cant seem to be able to figure out how to make holes in stuff...

This might help you. It discusses solid object modeling, and using the commands to cut holes in the plane. Autocad pwns ALL.

Catia is dutch to someone who has not used to it, but I know its a very powerful program.

Is there a way to create the disk, then create a smaller disk, overlay the two and "clip surface" before you extrude?

Well similar with CATIA then

Design the hole in 2D mode. Then switch back to 3D and you will have your hole.

When working in 2D and 3D it is still the same object. It is just different views so you can do different things.

Have you tried creating the hole in 2D and then turning it to view the object in 3D afterwards?

Simple method:

Create a disk that's the size of the hole you want. Line them up and go
Modify -> Solids Editing -> Subtract

Choose the larger disk to subtract FROM, and the smaller disk as the one to subtract.

The other way you can do disks is to create a cross section of the shape you want, then do

Draw -> Solids -> Revolve

You then choose your box (in the case of a normal disk) and revolve it from the top 360°.
