LISP to reload xrefs in all open drawings.

[bitslapped]

Would it be possible to create a command that reloads xrefs in all open drawings? Preferably only xrefs that have changed, but all xrefs in all open drawings would also be great

 

Thanks!

As far as I know, the reload method of the VLA Block Object will only operate in the active document namespace, so you would only be able to reload XRefs in the current drawing:

 

(defun c:rlall nil
   (vlax-for b (vla-get-blocks (vla-get-activedocument (vlax-get-acad-object)))
       (if (eq :vlax-true (vla-get-isxref b)) (vla-reload b))
   )
   (princ)
)
(vl-load-com) (princ)

I have a similar utility for this that also allows for Implied selection.

 

If no valid Implied selection exists, the code conditionally prompts the user to specify an XREF to reload by name. The prompt also includes an "All" option.

 

This tool has been invaluable for my work.

Thanks Lee. Would it be possible to cycle through open drawings, using this function on each one, and then jump back to the initial 'current' drawing?

Not using LISP, since when another document namespace is made active, the LISP function will lose focus and will hence cease evaluation. The only way I see that this could be done is by writing a temporary Script to iterate over the drawings and evaluate the LISP function on each drawing, though, this is less than ideal.
