Brep Brep Remove Intersection

Hi all,

I realize that this might be a simple question but I can't seem to solve these 2 intersections.

Below is a picture attached for your reference. I'd like to remove the intersecting rectangles on the given looped surfaces. I have tried all types of intersection solutions to no avail.

Any help would be much appreciated.

Thanks guys!

Hello

You can try the following

The curves must be closed for the split surface component to work. there is also some practice with lists and trees needed. In this example the polylines are organizes in a data tree with three branches (lists) each containing the three curves to be used with surface split.

Cheers

Hello Albert

Maybe i missed the objective? i thought what you are after is what the screen capture shows.

To generalize the trees need to be organized in way that each branch has the polylines to be intersected with each surface.the branches have the same number as the surfaces. If such organization is not possible, then having the all the polylines in a list and intesecting all of them with all of the surfaces will work to. You just have to have the polylines in a list and the surfaces in tree (grafting the surfaces list) with each surface in one branch. Default grasshopper data matching behavior will check each surface with all the curves. You will get some zeros to remove (because not all polylines intersect with the surfaces.

Hope this helps

cheers
