Suggestions for Creating a Ruled Surface

Here’s the curves outlining the surface model. I’m looking to create a “ruled surface” just not sure the steps, or best starting point. Loft straight sections creates ruled surface, but not from curves like these. Wondering if I need to start with a planar rectangular surface, then begin twisting into shape, or can these curves be used?

Thank you.

Hi ShubinJ - I’d add a straight line between the two upper ends and Sweep2 - you might use Add Slash to line up the isocurves but it looks like maybe only one or two are needed. If you do this in a wireframe viewport, it’s easier to see where you need to add a ‘slash’.


Thank you pascal
