Solving intersection of non-linear curves

Grasshopper

I’m trying to find perpendicular intersection of curve that passes over lines. However, that curve is not coplanar with the lines. How can I find the points on the curve wherever it will intersect those lines if it was coplanar with them?

I tried various components but couldn’t figure out.

If you project the curve to the plane it will also map its parameterisation, so you can use the t-values on the original curve (if that’s what you need, not sure):

Thanks. That’s exactly I was trying to do!
