Sample tubing from the tubing library. This is a representation of stock USA 4" steel. This is drawn as blocks with holes (no rounded corners or wall) to optimize rapid manipulation for more complex designs. Compoariso of fully accurate vs. blocky tubing should be performed to see the practical limits before FreeCAD starts bogging down. This is done with complex design in midnd - such as where multiple machines can be manipulated at the same time in one working window. Added April 25, 2016

Stock Square Tubing (with Rounded-Corners)

From Monica Log on July 14, 2013 - The result includes the stock pivot plate, all plates with 1 1/8" diameter holes and both 1/4" and 1/2" thick tube profiles. This is the file File:Warehouse-Rounded-tubes-and-plates-big-holes.skp. Note: tubing with square corners is preferable in Sketchup, as it can be put together much more easily.

Tibor gave me a great tip for the tangent arcs: lines should be made before arcs in order to make them. So instead of doing the inner arcs first, do the lines.

Made a tutorial for using arrays in the tube construction. In this case from a 4" tube, we get a 40" in less than a minute. Then, all that's left is cleaning details.
