AutoLISP: Globally Change XREF Attachment Type

If you need to Changeall of the way in which XREF’s are attached this routine is for you. This routine will change all XREFs in a drawing to either “Overlay” or “Attached.”

Here’s How:

• X2A <enter> = All XREFs to “Attached”

OR

• X2O <enter> = All XREFs to “Overlay”

That’s it!!!!

;Xref to Attach/Overlay										**
;Written by: Chris Wade										**
; 			  									**
;Version 2.1a  											**
;12/07/2011	  										**
;		 			  							**
;- Adjusted code to temporarily disable all reactors to prevent interference with LISP routine. **
; 			  									**
;Version 2.1	  										**
;12/05/2011	  										**
;	 			  								**
;- Changes that attachment type for all XRefs. 							**
;- X2A - Changes all xrefs to attached method.							**
;- X2O - Changes all xrefs to overlay method.							**
;	 			  								**
;- Known Limitations:		  								**
;- Viewport specific layer overrides may not be restored.					**
