Is there a "does intersect" node?

In my machine I am not internalizing the Breps, I just dont know of another way to share the gh file

How big is the Rhino file? Sometimes it’s better to not internalize geometry and this may be one. Post the Rhino file and the small GH file referencing it. That makes exchanging small GH files easier.

Can you elaborate or point me to what exactly does shift indices do and how we go from performing an intersection operation to a list of booleans?

Well, there isn’t much code there… PShift (Shift Paths) is done to match data tree structures. When the list length of BBX intersections (per branch) is zero, it’s False, otherwise True.

P.S. I just posted a file here where the value was so close to zero that it was treated as False, so I had to insert a isEqual (zero) component to get the correct True/False Booleans I need for the Cull Pattern ‘P’ input:

Aligning Planes X axis pointing to the same side of the curve

Well, this simple way works fairly well: [X axes_2023Feb9a] Going one step further, this finds the nearest surface at each point and uses that surface frame for alignment: You can wire either set of results to the purple group to see the X vectors.

NOTE: The IsEqual (Equal within Tolerance) component in this code is a cluster I wrote myself because the standard GH Equals component treats very small values as False (not equal to 0), …
