Hi Linker,

This would definitely be cool but it would be pretty difficult for me to set up right now - the blending stuff was easier because the geometry library already had things in place to do it. To do a custom profile curve I'd have to do quite a lot of new code.

There may be some other pretty big complications too - for a normal fillet, the distance between the edges of the fillet surface may widen or contract along its length on squiggly surfaces. For something that can be calculated like an arc, this forms a longer arc or shorter arc but of the same radius. A custom profile would probably be quite a bit different, in that it wouldn't work very well to just trim out a part of it like you can trim out an arc of a circle.

The other part that is complex is rounding at corner junctures, especially with more than 2 edges. This tends to require a bunch of specialized shaping slightly different than the regular profile, this may be really difficult for custom profiles...

Just doing the top bevel on a simple extrude doesn't really run into these issues, but the more general case of any edges does.

I think the way to solve this will be through template file support eventually. By this I mean being able to have a set of pre-saved starting files that have different settings all set up in them, like units + grid combos, etc... There would be something like a File / Template command similar to File / New (or possibly built into File/New), except it would let you pick a starting template file out of a set of different saved ones.
