How to flip the match direction of a curve?

Rhino Rhino for Windows

We all know the filleting tools are spread out across a frankly silly number of functions with inconsistent options, but I’m very surprised and frustraded that even the basic match tools are the same:

  • Match curve has no flip and no tension
  • Blend curve has flip but no numerical tension
  • Blend surface has tension but no flip (EDIT: flip actually shows up when appropriate, it seems?)

Also:

  • Blend curve editing allows the modification of the starting point with no issue
  • There is no explicit edit command for match, and if you try you get this:

Yep, Match is pretty primitive - among others, there is

RH-29606 Match: On curve

My doo-dad, for matching position and tangency only, I’m afraid:

I encountered this today again…

And unfortunately, I haven’t tried your script this time, because I match with G2 or G3 (which, again, can only be done with a blend curve, not match).

The DIR command and the Flip variant will reverse the direction of a curve.
I don’t know if that will work on a surface edge curve.

Well, two years later and I’m here again.

The dir/flip trick does not work, unfortunately. What’s the status on adding a flip to match curve?

Two more years, and BOTH OF THE MCNEEL EMPLOYEES REPLYING IN THIS THREAD HAVE RETIRED and match curve is still as basic as if it was Rhino 1.0.
