Pilou (and others)
I got it! On a Mac, you have to place the .rb file in the Library > Application Support > Google SketchUp 6 > SketchUp > Plugins folder. (This assumes that the SketchUp program exists in a folder called Google SketchUp 6 within the Applications folder.) Once I did that, the sub-menu included a Volume option. Thanks for your help, Pilou.
I have a 2-button mouse (could have used Control-click for right-click otherwise), so that's not it. I think I should see an entry in the About Plugins menu, also, but I don't.
Thanks, Pilou. There was no Plugins folder in my Google SketchUp 6 folder, so I created one and copied the VolumeCalculator2.rb file into it. I then created a component which has connected faces forming a solid which has a volume. When I right click on the component, I do not see a Volume option. I do not have a Plugins menu item, either.
Perhaps it is because I am using the free version of SketchUp. Or perhaps because I am using a Mac (OS X 10.5.2).
Any suggestions?
How do I add the VolumeCalculator v2 script to SketchUp?
