Sometimes you get a new computer, reformat, etc., and its hard to remember how you modified your Sketchup. Sometimes the old plugins are even taken down or the links get broken. There are very few good Sketchup plugins for .STL to .SKP or .SKP to .STL conversion, and recently the author of what seems to be the only import plugin has removed his version from his blog.
As a backup, I’m providing these plugins, verified to work on Sketchup 7 and Sketchup 8. Using them is very simple.
- All you have to do is download these two files to “C:\Program Files (x86)\Google\Google SketchUp 8\Plugins” or your installation equivalent.
- Close Sketchup and reload it.
- Look for the import option under file > import > stereolithography file importer.
- Look for the export option under tools > export to STL or DXF. Two screens will come up. For “select units” we use mm, and for “export to DXF option” we use “STL.”
