Which commands would I use to take an object and wrap it around a cylinder? Say I have something simple like a 3 x 16 x 1/4 rectangular plate and I want to wrap it around a cylinder, or shape it into a cylinder end-to-end.

Is there something engraved on this plate? Otherwise I'm not seeing the probem.

There are instances where a pattern can be on a rectangular plate. It would be nice to be able to wrap that pattern around a cylinder.

Yes, it would. I've tried, but I never got it to work very well. Basically, you have to slice the plate into tiny vertical columns and rotate them around the cylinder. If someone has a better way, I'd love to see it. On Tue, May 3, 2022 at 9:34 PM Joe Weinpert <joe.weinpert@gmail.com> wrote: > There are instances where a pattern can be on a rectangular plate.

There is a BOSL2 command, https://github.com/revarbat/BOSL2/wiki/vnf.scad#function-vnf_bend that can bend a polyhedron (a vertices and faces list) around a cylinder. But it can't work on geometry. It's pretty difficult to do something like that to geometry.

I just found a function in the BOSL2 library named *cylindrical_extrude()*. Been working with it. It is just what I needed. It also has some brother and sister functions that do similar things.
