This post describes the method to load an AutoLISP program in an open drawing.

Some basic & fundamental information before we move to the procedure

An AutoLISP program runs inside (in the same workspace of) an open drawing. Therefore it is necessary to load the program in each individual drawing you want to use the program in. You can load a program into a drawing at any time.

Once you load the program in a drawing, it remains loaded into that specific drawing until the drawing is closed. This means that you can use the functions in the program multiple times once you load the program.

The flip side is that you can’t unload an AutoLISP program once you load it except by closing the drawing.
