Hi Danny,

> Does the geometry library handle blend curve on a surface?

I don't think there is anything specifically for that, but possibly something like that could be calculated by doing a 2D curve blend inside of the UV parameter space of a surface and then pushing the UV curve up into 3D space. Although that kind of an approach can have problems if the control points of the surface are bunched together in different areas, as that also bunches together the UV parameter space as well.

It would probably be better to have one that sort of more marched along the 3D surface more directly so that it could control the spacing of the blend by 3D distance instead of in UV space. But that calculation is significantly more difficult to handle though.


Also I'm not sure if that would be very feasible to have directly in the Blend command without it exploding into a really complex command...

But we'll see... I am planning on doing an overhaul of the Blend command in v3 but the primary focus will be on handling a connected chain of edges.
