This takes ~three minutes to complete an Anemone loop and results in a single “Closed Brep” (solid) that, in theory, could be 3D printed. It uses Dispatch to separate the de-dupped line segments into horizontal vs. diagonal, then scales the diagonals by a factor of 0.98 (slightly shorter) before piping them, and then loops through the piped diagonals one at a time to SUnion them with the horizontal segments. A bit ridiculous but sometimes that’s what it takes.
