Thank you! I should have tried using "show all connectors", but ultimately I decided it was dumb to try projecting the curve in the first place because like you pointed out, the number of segments was difficult to match. The smarter way to get what I wanted was to leave the boundary surfac...

You both generally achieved what I can't but I still cannot figure out how. Did you have any difficulty selecting the projected curve (non-planar, on the Cone shaped Surface). If I try to select if for a Boundary surface it just says "error".

The title says it all, one curve is a projected curve, the other is 2D. The closed-loop from the projected curve throws an error if you try to select it for a boundary surface, but is selectable for a loft, however, the loft will not build. I've tried many combinations of guide curves or no guide cu...
