Best way to Loft or plane this opening

Rhino Rhino for Windows

I am trying to put a surface on the open /U shaped feature on this part. I tried Loft and Plane. I’m not getting anything. Am I using the wrong command? Or am I missing something? I plan to print the part in engineering resin.

Best,

Terry

I managed to patch the curves for the desired affect that I was looking for. This gives me a surface with a graph on it. I tried SelAll and Join. That did not work. Next I tried Boolean Union. Fail there as well. Anyone have any thoughts on what I’m not doing correctly? Here’s an updated version of the file…

Hi Terry - in this case, make a cylinder in Right that is centered on the obvious arc there - the Cen osnap will find it. Extrude the circle - or just make a cylinder - and then trim that with the edges of the original part

(If you leave that end square and closed to begin with you can get this result by just BooleanDifference-ing a cylinder.)

Thanks Pascal,

That makes a lot of sense. I’ll give it a whirl.

Cheers,
