Title: Snap to Spline

Is there a simple way to do to the more complex shapes?  Circulize is already possible, but what about custom shapes and things like squares?

Hi Mason,

I make blends between splines, but not sure if that is what you are looking for. This is using Retopo.

Examples:-
Circle > square / square > triangle

Splines:-

Resulting mesh from spline retopo:-

I managed to do that with a simple loft as well.  Requires 2x splines with the paremetric seam aligned between the splines.

But the loft solution doesnt seem to be conveniant.  ie:  square to triangle should only have 8 spans to complete, but to close the corners you had to get a really high number of spans.

I am thinking it would be more like a bridge from a polygonal edge to a spline.  The important step is to maintain the original edge spans.

what you suggest is just a loft of two splines, which will require cleanup.
