I’ve noticed that in Rhino 8, if I extrude a curve to a certain distance and then attempt to Contour that shape in Grasshopper, the last curve (ie. the top of the shape) is not included in the contour. If you extrude a Surface though of exactly the same curve, the last curve is included in the contour. This does not happen in Rhino 7 so I’m not clear if it’s a strange tolerance issue?
I’ve just noticed that if I make this a brep and select it, this problem does not happen. I am using the geometry pipeline command so it must be a bug with this somewhere. I cannot internalize the geo pipeline command, so I’m uploading both Rhino and GH files.
