I have a bunch of surfaces and a few reference planes. I would like to group the surfaces based on which planes they land between… I’m not new to Dynamo but this is stumping me and frankly I use Grasshopper more than Dynamo. Let me explain my process that I would follow in Grasshopper.
I would create consecutive domains from the Z coordinate from the origin point of the reference planes (circled in red below)… For Example 40.989 to 30.968, 30.968 to 20.968, 20.968 to 10.968, etc… Then I would take the Z coordinate from the 0.5,0.5 UV point on surface (circled in blue below) and get a T/F list that I can then use to group the surfaces.
Any thoughts, ideas, help or different solutions would be much help. Thank you
