This is more a geometrical modelling question rather than a technical question with the software. I hope its alright to post it here.
Haven said that, this is the issue: suppose I have a topographical model of a cliff, which varies in z, I have contours, the surface, the solid (patch surface capped at the bottom). I cant find a method to extract the “top edge” (red in picture) of the cliff. Anyone that can give me a hand thinking this through?
