Hi Marv, in MoI there isn't any special "part" versus "assembly" modes, there's just one editing environment and if you want you can have multiple objects in there or not.

So yeah if you need to create 2 parts you just build 2 parts next to each other, you don't go into a separate modules to do different things.

MoI is currently only focused on generating the 3D model data though, and not doing cut away or sectioned views itself directly. So if you need those you'll probably need to export your model to another CAD program for doing that part, Alibre or ViaCAD are some possible candidates for that.

You should probably just give the MoI trial version a spin to see if you like it or not, it's available on the download page of my main web site: http://moi3d.com/download.htm
