I need something to help me design simple mechanical systems. I want
to be able to "construct" an arrangement of, say, a series of cogs,
cranks and gears and see how they will move. I'm not sure whether I
need to look into CAD programs or Animation programs. (or CAD
animation?) But the simpler the better as I have no real need to do
large complex constructions (nor want to deal with any steep learning
curve). I just need something that will help embellish my pencil
sketches relatively quickly.
As you can probably tell from my question, I'm not very versed in what
is out there. Any help/directions will be appreciated.
