Externally Defined Commands

AutoCAD. commands defined by ObjectARX. or AutoLISP. applications are called externally defined. AutoLISP applications may need to access externally defined commands differently from the way they access built-in AutoLISP functions. Many externally defined commands have their own programming interfaces that allow AutoLISP applications to take advantage of their functionality.

For additional information on the commands described in this appendix, see the Command Reference.
