Summary: Miscellaneous scripts (no longer compiled into a plug-in, just scripts and toolbar) (developed primarily by Peter Harris).
I'm not supporting Rhino V4 or V5 anymore, though the old plugins for those versions are still linked at the bottom of this page. Also, please remember that these are free tools that you use at your own risk, of course.
I've created a collection of scripts that I've written (with the help of many people) which I turned into a plugin and a toolbar to go with it. The download link is at the bottom of the page. Thanks to all who have helped me on these scripts! Especially Pascal, David, Dale, and Mitch.
The commands currently available in the PetersTools plug-in are:
BOM and object properties tools
Geometry-creating or editing tools

E-mail me with your questions and feedback on this plug-in. I get very little feedback, so anything I get really helps!
