TIG, I verified that I do have the dim_angle.rb file in my C:/Program Files/Google/Google SketchUp8/Plugins folder of my Windows 7 PC, yet I can't see the angle dimensioning tool in my Tools menu like I can for my Windows XP PC at work running SketchUp 6.
Just for the heck of it I then downloaded and installed the French version of the plugin on my SU8 PC, but I still couldn't see the additional tool on the Tools menu. I wonder if other Windows 7, SketchUp 8 users are able to select this plugin tool?
Thanks for your help!
