Bending and Capping Ellipse

Grasshopper
1

Hi

New to grasshopper and Rhino and teaching myself through vids etc online.

I am trying to bend an extruded ellipse with Grasshopper so that I can adjust parameters once built.

The first thing I tried was (in gh) drawing the ellipse and extruding same but I could not make the Bend function work for me - specifically I couldn’t figure out what parameter “Angle” was.

Then I had a look at Bend Deform but as I want to bend the extruded surface in the middle I struggled (in my head) to link up the geometry with the Bend Deform function.

Lastly and the file I am linking here - again in gh I drew the ellipse, then I made it flow around an arc but when I try to Cap Holes I get an error saying Capping Algorithm failed to return a result

I’m sure I’m making some noob mistakes but I’ve tried a few other functions (without rally knowing how they work) to resolve the issue with little success.

Any help would be appreciated

No need for Rhino file.

P.S. You could use Project instead of Flow:

And use Offset Surface instead of Extrude:
