Darrel has been working on developing a set of efficient Rhino3D Shortcut Aliases (Google Code link) for Rhinoceros 3D, version 4.0. These are based on the work of Maxwan Architects + Urbanists in Rotterdam, and their long-term development of AutoCAD shortcuts that you can download from Dysturb.Net. He has developed the Rhino3D system in parallel for ease of interchange between the two softwares.
The installation is simple, and fully explained on the Google Code page (link above). You simply import the .txt file and overwrite the defaults. A Microsoft Excel file shows the list of used commands (and unused commands for future development). Feel free to make comments and suggestions for further commands on our BLOG!
