In SOLIDWORKS there is a feature to assign lines/shapes a relationship (parallel, perpendicular for straight lines; concentric, cordial for circles; etc.). And one of the most useful is the tangent relationship.
I would like to be able to, with the click of a button, assign a pair of lines/shapes a certain relationship that is persistent and updates all related elements when moved, rotated, etc. This would be similar to the join commant that allows two points to be connected and act as a single piece.
This would speed up a lot of the work I do with icons etc, where a geometric and engineering style approach is required.

You mean something like this?
Constraints could be interesting. If we're asking for engineering tools, a drawing scale setting could be interesting, too. I will usually do large drawings that need to be scale-accurate as 1-mm:1-in, but it would be cool to be able to use dimension palettes with native dimensions and just have the drawing scale.
