3D CAD Help Needed (Rhino)
There is a copy of Rhino 3D at my workplace. Nobody seems to know how to use it very well.
I have a very basic understanding of 2D CAD but would like to know how to draw a 3D tube frame chassis using both round and square tubing. What tools
do I use?
In Rhino I found that you can draw a line then extrude a tube around those lines. Can't seem to figure out how to create a square tube. Also it
starts the tube from the middle which isn’t always that helpful. I'd rather draw the frame using the outside wall instead - I hope that makes
sense.
Any ideas? Frame specific tutorials?

Rhino is a lot more suitable for complex curve and surface modelling.
It treats 3d models as surfaces, it cannot distinguish a solid...only a group of enclosed surfaces.
If you are really into the idea of modelling 3D, Rhino is probably not the best place to start...I taught myself, but only after experience of using
other 3D packages.
Solid works/pro eng is a lot simpler to get to grips with if you're starting from scratch

What Tom said.
Rhino is a surface modeller, not a solid modeller, which makes it quite difficult to use, unless you are designing car bodywork or complex surfaces
then its a bit easier.

Rhino has a quite good tutorial built in to the help menu - it worked for me

I like Rhino when you are just playing with different ideas and not looking for exact measurements/angles. It is so fast and easy to use IMO.
To make a tube, draw a square in top view, then draw a line through it in front view. Select the line as the rail, select "sweep one
rail" and then select the square as the cross curve. Play with the tutorial, and there are some forums out there too.
And yes, rhino is best for organic shapes..... damned amazing what people can do with it
