Diagonal lines only on surfaces


I want to make diognal lines on the sureface but when I connect those lines they also connect outside the surface. how can I get rid of those lines on the bottom?

And for opposite diognal lines, using mirror will be fine? or do I have to do the whole process again?

best regard

I didn’t check the whole details of your somewhat a bit messy definition, anyway, if you want to do some sort of diagrid paneling on a trimmed_surface, then, have a look at this approach.

You could cull the long polyline segments but that splits some branches into two curves. Rather messy!

So I guess I will have to find another cleaner way to do it than?

Thank you for the reply. I will try it.


So I have kind of solve it myself.
Using discontinuity and trim with Brep work fine.
Thanks for you advise as well.
