This page is dedicated to the system variables that are found in AutoCAD. The chart indicates which system variables are available in which release, which system variables changed and in which release (on going), and which system variables are new in the latest release. The PDF files are generated only a couple of times a year, while the chart is updated as new information is discovered.

Many thanks to Shaan Hurley at Autodesk for being the original source for this listing. Since both Shaan and I were working on a similar type of document, we decided to combine efforts into one project and the results of that effort are below.

	- Variable is available			- Variable is new
	- Variable was changed			- Variable not available

Note 1: Command aliases shown for some of the system variables are based on the latest release.

Note 2: Items in Bold and Italic are Read-only Variables.
