#OpenSCAD question:

if in wanted to emboss text around the outer rounded edge of a cylinder, how would I go about doing that? I don't know how to transform an object on a curve like that.

There is no general way to roll up a shape like that. All solutions for text on cylinder just position each character independently with a for loop over the string, so each one is still flat and it only really works with fixed width fonts.

while I use #gmsh and not openscad, and I haven't been concerned with wrapping 3dised text particularly, I think there isn't an especially 'good' way of curving a previously flat plane viz 3D meshing. If this were generally doable the world would be crazy.

If each letter is separate, I guess you would just have each letter's separate normal be radial to the cylinder and dphi would basically just be the normal spacing between the letters.

@screwlisp There are some good ideas here: 3dprinting.stackexchange.com/q…
