Hi eric, so in your original post in this thread you mentioned setting a "variable center point" - is that really how you'd want to define each arc piece (by center point I mean) ? Or would it be better to define the arcs by specifying a radius value? Setting a radius value would be closer to how filleting works.

The only thing that might be a bit odd about controlling things by radius value is that you'd probably be controlling the radius of the corner just behind the current point that you're placing now. Like if you draw a polyline with 3 points in it, the radius would apply to the corner formed at the second point location.
