G'day all,
I'm finishing off explanatory documentation for our office and I've just realised that I've never seen a Parabolic Curve Extension in a Profile. While that's not surprising given the nature of our usual work, I can't seem to generate one with any of the VC's - Circular, Sym. Para. or Asym. Para. All I can create is Line Extensions.
Could someone please enlighten me as to how generate one? Or even what it is?
TIA,
Trevor
