How to evaluate a curve?

[Phenzmnn]

Hello all!
I'm new to CadQuery because I am looking for a FOSS alternative to Rhinoceros3D/Grasshopper.
One major feature I am looking for is "evaluating" a curve.

What I want is to get a point on a curve along with its tangent vector by inputting a fraction from 0-1.

I would like use the output to position and align a new workplane.

Is this already possible with CQ?

Thanks for your help!

cq.Edge.positionAt and cq.Edge.tangentAt. Also works for cq.Wire
