3D Mesh Builder is a Unity3D Plugin that allows for geometric mesh creation and editing from within Unity itself with a Four ViewPort user interface that mimicks the 3D Studo Max user interface.

This project also makes use of reflection in order to work around some limitations of the public Unity API. Supports Unity3D 5.31 and above. Tested on Windows and OS X.
