The program supports tool changes; tools are represented by different layers in the drawing. Feeds are given using labels in the drawing. This seems awkward but a design goal was to require no editing of the generated file because all information needed to generate the output properly is stored in the drawing. REALIZE is distributed under the terms of the GNU General Public License (GPL).

This program originally generated G Code suited for MaxNC's software, but I've long since ditched that in favor of EMC, so currently it generates standard RS274 G Code.
