For 2D / 2.5D Techsoft 2D design is the best I feel... but it's not free :(
Otherwise any 3D package that can export in STL file format (even Google Sketchup may do this natively or with a plug-in) - not very "engineer friendly" but free :)
Then in chosen 3D package, export to STL and import into Modella Player (basic, but works well)
Or Modella Player 4 (more complex to get working with the PNC-3000 as it's not really designed to work) I wrote a converter that makes it work though...
STL files works well with the Rolands...
Have a root around in the files section; install, have a play and see what works best for you.
