But the jist of it is by running a sweep between a diameter and a rectangle. Rhino produces splines and ellipses. By manually breaking down the diameter and splitting in parallel to the radii on the rectangle. The surface iso curves that are produces are proper lines and arcs surface isocurves.
My question is how do i go about getting the cleanest lines and arcs surface isocurves without getting any ellipses and splines in my surfaces. Is there a simpler way than the manual intervention i’ve come up with? The cad program i’m bringing this in to for pathing can read them. But generally causes a ton of fits and sometimes has to be refit in the basic cad program itself before running any kind of pathing.
Thanks so much in advance for any ideas and / or direction i can take here!
