Cleaning Up After Your Reactors
 
 
 

Reactors are indeed very active. When you design an application that relies on them, you could very well spend a great deal of time crashing your program and possibly crashing AutoCAD as well. It helps to have a tool available to remove all the reactors you have added, if necessary.

The gpreact.lsp file includes a function gp:clean-all-reactors that doesn't do much on its own. Instead, it makes a call to the CleanReactors function. Add this function to your utils.lsp file by copying the following code to the end of the file:

;;;--------------------------------------------------------------;

;;;  Function: CleanReactors								;

;;;--------------------------------------------------------------;

;;;  Description: General utility function used for cleaning up  ;

;;; 		 reactors. It can be used during debugging, as  ;

;;; 		 well as cleaning up any open reactors before   ;

;;; 		 a drawing is closed.						 ;
