Hello everyone 
I have some unwanted curves when I intersect a geometry ( lofted sine curves) with planes made by perpendicular frames baseed on the bottom curve of the lofted surface.
I think I am doing it the wrong way : should I evaluate the lofted surface instead?
Also I would like to extrude rectangle along the output line (louvers) instead of the pipe and I canāt work it outā¦
Thank you for any help.
Best!
louvers from surface_f.gh (22.6 KB)
so planes are infinite in space
what happened was that the planes within my blue annotation is cutting the other wing. and vice versa the longer wingās planes are cutting the shorter oneās.
off the top of my head you can split that loft into two halves and do the intersection separately
You could also switch to Brep|Brep intersections and create planes (or āplanar surfacesā) that are finite in extent.
Hi David,
I have run into this issue before, where each rectangular brep representing the plane needed different dimensionsā¦ I wonder if there isnt a way to extract the āfirstā plane intersection, like a list item or so, I believe other components such as trim with regions organizes the tree so that item 0 is always the first piece of the trimmed curve and so on.
But what is the āfirstā piece when you intersect a shape with an infinite plane?
I think youāll have to filter the list yourself. For example by sorting all the curves by distance to your point of interest, then extracting the first item from that list.
Edit: ah, I think thatās pretty much what @HS_Kim did.
