Im having trouble with a Ruby plugin. What do I do?
First, open the Ruby Console inside SketchUp to ascertain if there are any obvious errors. You can open the Ruby Console under Window > Ruby Console. Then enter Ruby commands to interact with your plugin and watch the console for error messages. Once you’ve done that, the best course of action is to contact the plugin author. Check the plugin for a readme.txt or similar file, or look inside the .rb file itself, to see if they included contact information. If that fails, try visiting one of the user forums and asking for help there.
