I’ve been using other software for a long time now, but I was going to clean up som parts in Rhino and I thought the straight loft looked weird so I had to make a blend curve to check, and yes, there’s a difference:
Lofting with match tangents keeps the control point spacing of the loft. BlendCrv does not. I do not know how it would work to do something more elaborate in Loft, especially when more than two curves are are in the mix.
