Converting sketchup to STL and DXF
From CunningWiki
Converting sketchup drawings to stl or dxf allows you to prototype your part using a cnc mill or a 3d printer.
I convert it with a ruby plugin.
Here is the source I use. http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl
To install the plugin just paste the files here
C:\program files\google\google sketchup 7\plugins
To use:
1) Restart sketchup
2) Draw your model
3) Select the component you want to export. not selecting will use the entire model
4) Go to TOOLS >> Export to DXF or STL
5) Choose the Export Unit >> Choose Inches
6) Choose Export to DXF Options >> Choose STL
7) Save the file somewhere
