Yes i did, it is a great tool. But it is still in active developement so next week it produces different result from last week. Still, sometimes when i really need to use it, i send data to Rhino WIP via ghdata, process it there, and return it back to my rhino 8 algorithm. For this post specifically, i was looking for something more robust in cases when i need to cover a hole with at least G1 continuity to near edges. Overall i am waiting when mcneel release their multimatcher into api, this would allow some more or less quality surface modeling in grasshopper.
