I'm looking for an easier workflow for creating a somewhat complex surface.

Right now I have to make a bunch of 3D Splines, guide curves, etc in order to get a body that is comprised of a 2D profile extruded up to a 3D surface.

Is there a way to extrude a 2D profile up to a 3D spline in a 3D sketch?

I'm attaching a simplified version of this part, along with some screenshots of what I am trying to achieve.

The actual part has about 100 of these points making the 3D spline, and I need to do a few dozen of them. So, Trying to simplify the workflow as much as possible.
