according to MichaelAtOz' suggest. follow http://forum.openscad.org/file/n9262/textManipulation.scad I add this module: rotate text and cut. ================= module rotate_cut_text(){ union(){for(i=[0:1:slices]){ intersection(){ rotate([0,0,i*step_angle+step_angle/2])translate([-i*slice_width,-radius,0])children(); rotate([0,0,-90+i*step_angle])rotate_extrude(angle=step_angle) translate([radius,0])square([text_height*2,height],true);} }} } rotate_cut_text()vtext(); =================== <http://forum.openscad.org/file/n20197/2017-01-23_11-14-54%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE.png> the result slices is more continuous. <http://forum.openscad.org/file/n20197/2017-01-23_11-16-00%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE.png> -- View this message in context: http://forum.openscad.org/It-seems-no-way-to-put-text-on-the-curved-surface-tp20182p20197.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Another very general approach is discussed in http://forum.openscad.org/Wrapping-text-around-a-complex-geometry-td18145.html. It requires saving the OpenSCAD text in AMF format, processing it with a Python program and feeding its output to an OpenSCAD program that maps the text on the target surface.
