AutoCAD 2 D is easy enough, haven't tried the 3D
yet, but I taught myself the 2D, but your right being taught would be much
quicker.
Mike,
I
was wanting to learn CAD but it seems I do better in a classroom setting for
that sort of thing. Bottom line, I signed up for some CAD classes at the local
community college. …….. which also qualified me for the academic pricing on
the software.

Thanks
Monty. Alibre was the tool I was thinking of. Never seen Rhino but I will take
a look. Building an airplane is sort of an excuse to learn the tool. I suspect
that I could design/build what I want without it. But it might help me
visualize the end result before I go to far down the wrong path. Clearly I'm
not going to invest huge $ in a cad package to build a one
off.

If you are going to
design an airplane I would go with Rhino http://www.rhino3d.com/. Not free. Not
parametric. But you will have an easier time transitioning to it with your
experience. It is capable of doing the surfaces necessary for an aircraft.
Autocad experience translates nicely into Rhino. The solid modeling is pretty
crappy in Rhino, but I never use it.
It is a very good
and cost effective package for doing parametric solid modeling. It also has a
sheet metal module. The free version is not the most capable thing in the
world. I think you can upgrade to the hobby version for very little money. I
have the full blown professional package. I like it. It will do 95% of what
Solid Works will do for much less money.
If you need to be
able to do real parametric surfacing for something like an aircraft,
forget all the mid range packages and ProE, nothing short of Catia or
Unigraphics is going to work satisfactorily. For either of these you will
be spending $20K+ and about $4K/year on maintenance.
Makes Rhino look
REALLY GOOD.
Parametrics can be
more trouble than they are worth with complex
models.
If I really must
have a complex surface with parametric detail, I create surfaces in Rhino and
import them to Alibre. I add all the parametric detail
there.
Try everything else
first, but you won't regret spending the money on Rhino. I've been using it
since Rhino 1.0.

Some
time back I think it was Monty Roberts who posted about a free parametric
modeling software package. I lost the link (and name of the software) when
my last PC died. I didn’t grab the software at the time because didn’t feel
I had the time to learn to use it. But I'm interested in learning now. Monty
(or anyone else for that matter) do you still have a link? Did anyone dive
in at the time and try it? If so, I'd like a little feedback. I have lots of
experience with 2D Autocad and a little experience with both ProE and
Solidworks.
I'm
starting to think seriously about my next project. I've given up waiting for
Van to finish his RV-11 motorglider and I've just about convinced myself
that I can design and build my own version. Would like to do some doodling
in a 3D cad program.
