Datum Plane on Curve

Hello everyone.

Got a challenge that maybe someone can help me.
I need to create a Datum plane on a Curve at al specified point on the curve.

The datum has to be normal to the curve and Orientation on Curve Parallel to X-axis.

I recorded a journal but OMG is massive for just one feature.

I'm working on it today, if I manage I will post here.

Thanks Kico
