I frequently need a plane which is tangent to two intersecting curves, and/or a line which is normal to two intersecting cuves. My method for creating these is:

- Plane with AroundCurve option, around one of the curves, centered at the intersection.
- Plane with AroundCurve option, around other of the curves, centered at the intersection.
- Intersect the planes to create a line normal to the two intersecting curves.
- Plane with AroundCurve option, around the normal line, centered at the intersection.

Presumably this could be scripted. Is there a simpler method?
