How would I go about extracting the boundary corners of a curtain panel. I can extract the boundary PolyCurve, but have hit a dead end.

For context, I’m inserting adaptive components over a curtain panel grid. The Curtain wall gives more flexibility compared with divided surfaces.

Thanks kulkul,

For some reason my lunchbox nodes weren’t loaded properly.

I knew there must have been a node for this somewhere.

Here is a complete graph that places the Adaptive Components, too:

(Filters for panels with 4 points to match the number of points in the Adaptive Component.)
