SolidWorks handles all of these quite well, regardless of what you are
designing.
Yes, but would you find those same features in a CAD tool oriented more
towards industrial design?

What about CAD/CAM?

Very true.
So is the main difference then between ID and MD CAD packages primarily just
the tools (i.e. menu picks) the designer is given for creating models, where
an ID oriented package gives you better tools for doing the curvy, swoopy,
organic stuff, while an MD one gives you better tools for creating common
"mechanical" shapes and solids?

If you are going to get serious about product design, I personally
think you will wind up with more than one CAD package, and that is just
the way it goes.
If you buy SolidWorks, you really will likely want the Pro version and
all those addins as they are very valuable additions. Likewise, you
may find you eventually need the full "Mold Flow", and if so, the cost
of the full package for analyzing your plastic molded parts will set
you back another significant 4 figure chunk of dollars.
If you get heavily into surfacing, you may then have to buy a package
(Rhino or others) to do advanced surfacing, but I doubt any one package
will replace the need to have a CAD application like SolidWorks. I've
bought, used and tried a lot of 3D solids from InCAD (early 90s on the
mac), Ashlar Vellum/Cobalt/..., SDRC I-DEAS, AutoCAD's smorgasbord, &
looked at ProE, Unigraphics and I've stuck with SolidWorks for ease of
getting up to speed in getting real work done fast.
It really depends on what environment you are working in. If most
people you are going to work with use ProE, then I'ld bet you would be
best using a directly compatible product so your collaboration works
fast.

Answer = no, that's too simplistic, but you're headed in the right
direction. Think of MD (or MED) as not only the ability to create
prismatic shapes and solids, but also to use those in proper fashion to
create and sometimes analyze complex assemblies. So, there is the
ability to create and handle assemblies with large numbers of parts and
also (absolutely necessary) subassemblies, to deal with geometric
relationships between components, and to generate engineering drawings
(with proper tolerances) to create manufacturable items, to calculate
centers of gravity and moments of inertia based on density information,
and to included metadata useful in bills of material, etc., etc., etc..
Industrial Design often requires some limited amount of the above (but
often minus the need for engineering drawings) and also the necessity to
do other things besides just "swoopy" features. Creating draft for
molds, for instance, especially since a large percentage of ID design
work is for injection molded plastics. But there is SUCH a huge overlap
of requirements (e.g., draft is also necessary for most kinds of
casting/forging design) that most of the major-player CAD companies out
there have found it to be in their best interests not only to provide
only pretty complete tools for one, but also to provide pretty complete
tools for the other . . . SolidWorks included. Most of the differences
between CAD softwares in these areas are in degree only, and in the
number of bugs and quirks, and in stability and in quality of technical
support. There are exceptions. IronCAD targetted mechanical design
specifically and left out most tools for anything else. Think3 went the
opposite direction. Neither company is doing well as a result. McNeel
(Rhino3D) is probably an exception there also -- they've done well
enough by targeting a small segment, but doing it quite well and in ways
useful to people who use other softwares.

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

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. |

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.
