Tubing Tool
This tool allows you to place or draw standard tubing shapes.
The menus for Pipe are for standard weight (Schedule 40) pipe,
Pipe-X for extra strong (Schedule 80) pipe and P-XX for double-extra
strong. The other sizes are for standard sizes for seamless alloy
steel tubing.

And in 3D mode

You set things up in the tool's dialog.

Then draw a 3D tube. |
