Ron,

Been pondering when I started to move from using profiles to more working form primitives. I think the techniques that I had to learn to make primitive my preferred approach was getting the hang of sketch planes and drafts on extrusions.

Previously when I wanted a dovetail I would always do a profile. But then I was shown how to put a draft angle on an extrusion and that made something like the dovetail cut on the bottom of a Sherline X table into just a rectangle cut extrusion into the table with a draft angle on it. Much easier than a profile.

Sketch planes came in when I needed to learn how to put a radial hole on a cylinder. Then it became angled sketch planes and splits.
