These are the macros and python scripts needed to build Walkabout and Step size tool palettes, in Rhino for Mac version 6, that matches the Rhino for Windows Walkabout tools. The macros are all below; instructions for making the new buttons are here. The icons for the buttons can be downloaded here.

Walk forward:
