I have a use case similar to the above topics, but a little simpler I think in some ways. I tried to have a turn at it, getting close, but maybe I’m missing some extra helpful logic for it.
What I’m trying to do is create the longest line inside of a closed curve, i.e. furthest distance that can be made between two points on a single closed curve. My definition nearly works, but it doesn’t give me a single solution - depending on how the object is initially rotated, it calculates a slightly different line and longest length.
