UPDATED: 04/30/2014 Added bold=
(be sure to download the latest version of write.scad to use this feature)
bold=0 (not bold) bold=1(bolder by 10%) bold=2 (bolder by 20%) etc.. (fractions work too) Thanks MichaelAtOz for minkowski tip :)
examples
write("Hello world",bold=1)
or
writesphere("Hello World",[15,15,15],12,bold=.5);

UPDATED: 04/24/2013 M_G pointed out that space didn't work properly on writecube.. (fixed) Thanks M_G!!
UPDATED: 03/06/2013 Added Help file for creating fonts.
I have looked everywhere for an easy way to write on my 3d objects. Everything I could find was hard to manipulate, so I decided to give it a shot myself. Hope you like this as much as I do. I'll try to answer any questions you have.

write.scad Routines:
write()
writecube()
writesphere()
writecylinder()
writecircle()

Fonts:
letters.dxf (change in write.scad)
orbitron.dxf
braille.dxf
knewave.dxf
BlackRose.dxf

writecylinder specs in testwritecylinder.scad

Be glad to add more fonts if requested, or give details to make your own.

openscad version 2011.12 or later is required to be able to run this code. Be sure to download the latest version from http://www.openscad.org/

Put the files (write.scad) and (letters.dfx) in the working directory with your open scad project. refrence write.scad in your code...(use
