This is an EXCELLENT tool. I don't see how anyone using Sketchup on a regular basis can live without it. I'd rank this in the top five MUST HAVE extensions.

When I first installed this and could not get it to work. I finally did get it to work and my problem was operator error I was using it wrong. You first select WHAT operation you want to perform THEN the two components you want to operate on. Works like a charm, then.

I'm usually pretty good at following directions, as per the OSCoolean videos which are short and show absolutely what you need to know, but one gets into the habit of first "selecting" then "operating" for core and plugin functions. Hopefully, this experience will teach me to be more alert.

Others have mentioned this in previous posts but I thought I would also bring it up: While using the Ruby Console to debug for why this plugin was not working, I did not see error messages but warnings about "deprecated".
