Any way to curve along a cylinder vertically? #7

Any way to get text to follow the curve of a cylinder when it is rotated 90 degrees?
In this snippet, you can see it appears flat, and doesn't curve along the surface of the cylinder.

rad1=3; rad2=3; %cylinder(r1=rad1,r2=rad2,h=40, $fn=100); //Partially visible "base" object text_on_cylinder(t="Text",r1=rad1,r2=rad2,h=40, rotate=90, font="Liberation Mono", direction="ttb", size=5);

Hi Chris,

If I understand you correctly then the simplest way I can think of doing this is to use the text sitting "flat" as you mention and then to create a separate sphere of slightly larger radius to cut off the text with the spherical curvature you seem to be after.

I am not using this code currently so can't execute your sample but if you post images of your results I can provide my thoughts.

I meant cylinder on the cutting shape. See the examples for how this was done with a sphere - see rounded.
