Match curve command

using match curve to adjust tangent on a wire frame curve using a surface edge to match from, rhino 6 puts a dup edge curve on the surface edge, rhino 5 didn’t do this. i’m wondering if there is a way to turn this off ?

no, not using average curves. i very seldom use average and i pay close attention to making sure it is off.

Hello - I think I remember this was broken and then fixed - can you run SystemInfo in Rhino and post the result?
Yeah…
