Mad Mango's Sketch Census Tool file size: 253847 bytes
Inspired by a thread in Eng-Tips.com, the inital code was provided by MadMango. I was feeling generous and offered to convert it into an addin. Here it is.
Download zip file, unzip, and run "setup.exe". Be sure SolidWorks is not running at this time. Once restarted, you will find a new menu item under "Tools --> Esox Republic Tools --> Mad Mango's Sketch Census Tool". There is also a toolbar available. I'm not much of an artist, and there's only so much one can do with 15x16 pixel space. It's supposed to be a mango with a mad face.
To use, preselect a sketch, sketch segement, or sketch point, then pick the menu command or toolbar button.
