In the attached file I have three arcs. I am trying to do a loft among them. For some reason, the loft command wants to go to the far side of one curves and loop back.

are you picking them in order? or just selecting them all?
Yeah - I’ve seen this before- the arcs are not matching,
and since they are rational curves, the surface overshoots. You can clean up using the Rebuild setting in Loft - 10 points seems good. Or rebuild the arcs ahead of time to someything accurate - degree 5 and 12 points makes a good approximation of a 180 degree arc.
