Without posting your model, no one can be sure… There are several possible issues. Your first image looks like the curves (lines) start/end in opposite directions? One way to handle that is Loft ‘O’ (Options) | ‘Align sections’:
thanks for the kick response, I didnt post the definition because its super basic I was just stating on it, just a curve and loft command at this point.
I actually saw the “align sections” solution at another post but it didn’t work for me and I dont know why. I’ve used loft a few times already and this is the first time this has happened to me. Just so you know the lines I am using where done with a “make 2D command” don’t know if that has anything to do with it
