I can't win

This proves beyond a shadow of doubt that PTC are deliberately messing with me.

So... I'm looking for an endpoint condition that's not tangent, and not-not tangent. Something like the way it takes 3 attempts to get my micro USB in the right way when there's only two sides. It must be a quantum-something.

PTC wants you to buy the style extension! Of course they are messing with you

Got a little more context to your challenge here?

It's okay, I was just venting. It was a boundary blend, 2 curves in one direction, 2 in the other. Tangency conditions on the two curves in the one direction. The kind of thing I've done a million times before.

Happy Labor Day weekend for all my American readers!
