plane (instantaneously) defined by curve

[roambotics_scott]

There is a way to make a plane along a curve but there should be an easy way to generate a construction plane that's (instantaneously) tangent to the curve as well in one step.

Not sure how you want this to work. At any point on a curve there will be a tangent direction but a plane can be created 360 degrees around that tangent vector. You could use the normal direction if the curve is not linear. What is it you want to do with this?

[roambotics_scott]

Yeah I'm thinking that you have the plane defined by the tangent and instantanous normal vector (assuming non-zero curvature).

As long as you're doning that, I'd add an option for the third plane perpendicular to those two as well just for completeness.
