Flat arc to 3D curve I have a task to create a 3D model from a paper-based plan, part of which illustrates a curve to be cut from aluminium and then bent into an arc for use vertically  – easy in life, perplexing (so far) in Blender.
It's almost like I need to take each vertex on the outer edge and rotate it around the corresponding local X axis of the corresponding inner vertex.

Can anybody suggest a way to take a 'C' shape, as shown above, and turn it 'edge on', please?
I've spent an inquisitive morning tinkering, but it's time to ask for a hand now.
If I understand correctly, what you could do is:


Use your picture as a background image.
Create a cylinder, extrude inwards.
Only keep an arc.
Scale on the X axis (because it seems a bit deformed).
Make sure you've applied the rotation with ctrlA.
Give it a Simple Deform modifier / Bend mode. Give it the Angle value you want.
