This is a plugin script for Google's free 3D design program Sketchup. The free version of Sketchup has limited file export options and many CAM programs will not recognise the native Sketchup (SKP) file format. This plugin allows you to export your Sketchup model as a DXF or STL files readable by most CAM and 3D printer software.
The code for this plugin is opensource - and hosted on github.
Sketchup introduced an easier way to install plugins. Download the RBZ version of the plugin (skp_to_dxf.rbz) to your harddrive - it is a zipped file but don't extract it. Then in Sketchup click on the install extensions button. It's found under Preferences > Extensions > Install Extension. Clicking this button will bring up a file browser window where you can can select skp_to_dxf.rbz from your harddrive, and SketchUp will then install it for you.
This is an alternative method which will work on Sketchup 2015. To install the plugin you need to download the file above (skp_to_dxf.rb) to your Sketchup ShippedExtensions folder.
This is an alternative method which will work on all versions including 6 and 7. To install the plugin you need to download the file above (skp_to_dxf.rb) to your Sketchup plugins folder. This installation method will work with Sketchup 6, 7, 8 and Sketchup Make (Sketchup 2013).
After copying this file, start Sketchup and you should now have an extra menu option (Export to DXF or STL) in the Sketchup Tools menu.
