Hi all,
Basically I want to create a tunnel like structure, made of a series of twisting ellipses and connected by "cables",
thanks Manuel help me to solve the cable problem btw. What I want is intersect the ellipses with the cables and make holes on the ellipses. But when I tried intersecting the two mesh/surfaces. not all the intersecting circle appears. I do not know why.
I didn't get a chance to open your definition, but is it possible you're using shortest or longest list instead of cross reference? if you want every brep in list A to intersect with every brep in list B, you need to use cross reference data matching.
