Hi everyone,
very basic questions on how to split surfaces using curves, without reshuffling the initial order
Selective split problem
The problem of the standard split component (SrfSplit) is that the curve projection also splits other nearby surfaces, even though the curve does not touch them.
I want to avoid splitting those unintended srfs, and only split srfs if the curve actually touches/intersects them.
Preserve surface order
After splitting, I want to keep the original tree paths order of the input surfaces, as it is in the gh script I shared. The issue with that is with the standard split component (SrfSplit) that is not splitting the surfaces as I want.
The script is full of other stuff and difficult to clean up just for sharing. I’ll do it in case no one can give me an easy reply, as it seems like a pretty basic operation for many experts here who are used to working with complex geometries.
Project Point (using curve midpoint), Surface (or brep) | Curve intersection, Collision One|Many, etc., but you might not even need them, some times PullPoint is enough to know if an object (line) is on a surface.
data trees are respected, meaning if branch {x} was containing 3 different surfaces before splitting, then after splitting you will end up with additional branches like:
{x; 0} (split fragments of that first original surface, or whole surface if no split)
{x; 1} (split fragments of that second original surface, or whole surface if no split)
{x; 2} (split fragments of that third original surface, or whole surface if no split)
. Like exactly what your second image shows:
