Bending an extruded surface

[lenianiva]

If I have a sketch and extrude a solid from the sketch, is it possible to bend the extruded solid as if it was fed to a rolling machine?

I don't have a code example because without this bending operation I don't know how to model this effect.

No, not right now. Do you want to map the pattern onto a face?

I want to map the pattern onto a cylinder and cut out a hole in the cylinder

If you have a 2D array of things, you could map them to the parametric space of the cylinder, position and project onto it. Take a look here:

cadquery/cadquery/occ_impl/shapes.py

Line 5178 in 2726421

rv.append(f.project(base, f.normalAt()))

it should be few lines of code actually
