How Can I - Offset Curve, loft & Extrude all with sliders

Grasshopper
1

New to GH.
I am trying to create a variable depth road surface from a single curve.
I have the Curve and Offset Curve portion constructed on a Cplan. I can’t get the curve & offset to loft.

Any thoughts.

  1. Ask questions more thoroughly in the forum
  2. Add a screenshot/drawing of what you trying to achieve
  3. Upload the current state of the file you are working on so we don’t have to start from scratch

I think I figured it out. This seems overly complicated though. You can see attached if you like.
