CAD for machine design vs industrial design?

IDs might require things like G2 tangency and a broader range of
surfacing tools. For example the ID part of Unigraphics (NX) can take a
scanned in sketch and use it as a basis for a cad model. IDs might also
require more splines and the like.

On the drawing side, IDS might require more types of pictorial views
like 2 and 3 point perspective and oblique as well as the ability to
make renderings. IDs might also require the ability to output to 3D
printing type devices or to make sketch like renderings of a model.

 

While telling us of all the other things & systems you need .....
and I doubt you've covered actually making anything.

 

After reading Mark & TOP, I have to say that you are still faced with
the choice of starting somewhere, and just expecting you will likely
broaden your 3D applications later.

SolidWorks offers a broad array of tools to do actual products and
machines in a whole variety of ways with drawings and bills of material
& some simple Cosmos & Mold Flow built into the SWKs Pro package and
then the large array of add-on 3rd Party providers, and as such is a
darned good starting point.
