I am working on a project right now
seating
this is the assembled frame CNC cut
I use the PHLAT BOYZS plug in(http://phlatforum.com/xenforo/) (file:///C:/Program%20Files%20(x86)/Google/Google%20SketchUp%208/Plugins/Phlatboyz/html/help.html)
G code tool path in sketchup V8
The tool path is produced then the gcode is saved
GCODE WITH TOOL PATH AND THE PLAT TOOLS (PATH AND DOG BONE)
gcode in text
GCODE SAMPLE
2 things the plugin works best in V8
and lots of sides on circles and arcs
