You may want an STL importer plugin for SketchUp if you plan to edit STL files from other computer aided drafting software, such as CAD, Solidworks, etc.  Here is how we do it:

If using the new Sketchup Make 2014, follow these instructions:

STL IMPORTER/EXPORTER: In order to export a file from Sketchup for 3D printing, we must be able to export STL files. We need to install a plugin for this. In the top menu, go to “Window.” Click on “Extension Warehouse.”  A new window will now open. There will be a menu on the right side of the window. Click on “Sketchup STL.” Click the large red “Install” button on the right side. You will now be prompted to login to your Google account. After logging in, you will have to Click “Install” again. Accept the terms and click “Confirm.” You must now click “Install” for a third time to start the installation. A window will come up and warn you that this extension will have access to the file system on your computer. Click “yes.” Sketchup will now tell you that the Extension has been installed properly and that it is ready to use.
