I've just discovered what design tables are for,, and have a vague idea of how to use them to make multiple configurations of a part.
This will save me time in some of my assemblies no doubt, but what I would like to know is how to use the design table so I only need to use a single sldprt drawing for an assembly that uses 3 different parts.

IE, if I wanted to weld 3 tubes together in parallel, a 1", 2" and 3", how could I use the design table to draw a single pipe with those 3 configurations, then insert those configurations into the assembly, instead of having to draw 3 differently sized tubes.
