The shaft was left in for reference only. The focus is on the
housing using aluminium tubes as per your suggestion. Also I don't
know if you looked at freecad it has modules for shafts and stress
analysis. I downloaded the Linux version as I use ubuntu , to play
around with. Zahid Rahman


I just installed it.

Looks like it might have potential. I have not been able to draw a
simple line yet. A vast majority of the tools are faded out.

Send me a file with a step by step on how to load and view.

There are dozens youtube video tutorials on freecad
Here is 2:43 minutes  to start off with.

Unfortunately it was written by inexperienced 3D cad users.
Using 3D primitives is not the way to go. That is way too
complicated for a user interface.

Rhino has no 3D primitives. Just 2D primitives. Circles, lines, ovals,
squares etc.,etc..

You make a 2D sketch and it becomes 3D when you extrude it.

There are four views on the screen. Front, bottom, side and perspective.

A far far easier and faster way to learn 3D. Much much simpler.

One can start drawing in Rhino in five minutes.

Free CAD reminds me of Solid Works. Another nightmare user
interface :)

According to some of my CAD expert and teacher friends Solid Works is slowly
sinking into the mud. Fortunately.

Spend the money and get Rhino.
