====== WalkAbout tools for Rhino-for-Mac ======



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 [[rhino:mac:uniqueui:walkabout:addmacros|here]]. The icons for the buttons can be downloaded {{:rhino:mac:uniqueui:walkabout:walkabout_icon_set.zip|here}}.

==== WalkAbout- ====

**Walk forward:**
