KWiKTools for Autodesk Inventor
KWiKTools is a collection of tools that I have been playing with for my own use. I have attempted to clean it up a little in order that others can use it.
It is definitely a work in progress. It may get updated often, or not at all, depending on free time and my needs for improvements or new tools.
It is freeware, but as always if you find it useful don't hesitate to Donate :~)
