plackowski Posted December 27, 2016 Share Posted December 27, 2016 I think I'm encountering the same problem that was not resolved here. I'm trying to set all the layers of an xref to layer 251. I found two codes online, posted below. CVX: (defun c:cvx (/ ent_data);;changes all layers in selected xref to color 251 (setq ent_data (entget (car (entsel)))) (command "-layer" "Color" 251 (strcat (cdr (assoc 2 ent_data)) "*")"") ) X251: (defun C:X251 (/ EN L X ad layers) (command "UNDO" "BEGIN") (setq EN (nentsel "\nSelect Xref: ") L (cdr (assoc 8 (entget (car EN)))) X (substr L 1 (vl-string-position (ascii "|") L)) ) (setq AD (vla-get-ActiveDocument (vlax-get-Acad-Object)) layers (vla-get-Layers ad)) (if (/= (vl-string-search "|" L) nil) (progn (vlax-for layer layers (if (/= (vl-string-search (strcat X "|") (vla-get-name layer)) nil)(vla-put-Color layer 251)) ) (command ".REGEN") ) (princ "Not an Xref!") ) (prin1) (command "UNDO" "END") ) I used the CVX routine for a while, until I discovered that it doesn't work if I select xrefs that are attached to overlaid xrefs. So I tried switching to the X251 routine, but if I use UNDO, the changes aren't reflected until I REGEN the drawing. I tried using an undo group as suggested in the linked post, but that didn't change the result. Any advice? Quote Link to comment Share on other sites More sharing options...
Roy_043 Posted December 28, 2016 Share Posted December 28, 2016 Try: (defun c:cvx ( / lst) ; Changes all layers in selected xref to color 251. (if (and (setq lst (nentsel)) (= 4 (length lst)) ) (command "_.-layer" "_color" 251 (strcat (cdr (assoc 2 (entget (car (cadddr lst))))) "|*") "") ) (princ) ) Quote Link to comment Share on other sites More sharing options...
