The functions are not available in earlier releases and are a nice alternative to using the VLAX functions that are only available in AutoCAD 2012 on Windows. The functions can be used to access both graphical and non-graphical objects in a drawing. One of the best features of the new release is the ability to access and modify object properties with a set of 4 new functions. If you are planning to upgrade to AutoCAD 2012 for Mac (or AutoCAD 2012 on Windows) and use AutoLISP, there is some exciting news.
