I’m trying to trim a surface defined by a curve from Rhino. My initial idea was to create a box from a rectangle, that can be used as a cutting object. This needs to be a box, because i need to trim surfaces in multiple planes with the same cutting shape.
This setup does seem to work great with my first attempt. However, my second input curve doesn’t return a trimmed surface. Does this have something to do with how Grasshopper defines my curve geometry? Curve 1 is a ‘Closed Planar Curve’ while Curve 2 is a ‘Referenced Periodic Planar Curve’?
I hope some of you can help, or tell me how to improve my file. (Some of the components may seem unecessary, but it’s taken out of a bigger context.)
What I try to attempt. Successful trimmed surface from Curve 1
Failed trimmed surface (with cutting shape) from Curve 2
