vladthedog Posted April 2, 2009 Share Posted April 2, 2009 I did try to search the forum before posting, but since I'm not even sure what I'm looking for I gave up on that. Ok, so I'm playing around with lisps. i have multiple setq lines that are using ssget to select items in various layers. The lisp works just fine when every layer that i use ssget has something in it. However, if a layer has no items then my lisp will stop working and just say "select objects". What do I need to do for the lisp to say to itself "ok, i am selecting 0 objects, lets move on" ? Thanks. Quote Link to comment Share on other sites More sharing options...
rkmcswain Posted April 2, 2009 Share Posted April 2, 2009 We are going to need to see the code Either attach as a file or paste it inline, using [noparse] [/noparse] tags, like this: (defun foo () (function) ) Quote Link to comment Share on other sites More sharing options...
vladthedog Posted April 2, 2009 Author Share Posted April 2, 2009 don't laugh at it (defun c:danger (/ byby delcab deltext deldiv delsplash delsqft deldims) (setq byby (ssget)) (command "_.ERASE" "_All" "_Remove" byby "") (prin1) (command "-layer" "s" "0" "") (setq delcab (ssget "x" '((8 .

Lee Mac Posted April 2, 2009 Share Posted April 2, 2009 Maybe: (defun c:danger (/ ss byby) (if (and (setq ss (ssget "x" '((8 . "cab lines,text,drawing divider,splash,sqft,dimension")))) (setq byby (ssget))) (progn (command "_.ERASE" "_All" "_Remove" byby "") (command "_.ERASE" ss"")) (princ "\n<!> Nothing Found <!>")) (princ)) Quote Link to comment Share on other sites More sharing options...
rkmcswain Posted April 2, 2009 Share Posted April 2, 2009 Try replacing this... (setq delcab (ssget "x" '((8 . "cab lines")))) (setq deltext (ssget "x" '((8 . "text")))) (setq deldiv (ssget "x" '((8 . "drawing divider")))) (setq delsplash (ssget "x" '((8 . "splash")))) (setq delsqft (ssget "x" '((8 . "sqft")))) (setq deldims (ssget "x" '((0 . "dimension")))) (command "_.ERASE" delcab deltext deldiv delsplash delsqft deldims "") ...with this (if (setq sset (ssget "_X" '((8 . "cab lines,text,drawing divider,splash,sqft,dimension")))) (command "._ERASE" sset "") ) Quote Link to comment Share on other sites More sharing options...
David Bethel Posted April 3, 2009 Share Posted April 3, 2009 If it is all dimension entities not a layer named dimension, then try this: [b][color=BLACK]([/color][/b]and [b][color=FUCHSIA]([/color][/b]setq ss [b][color=NAVY]([/color][/b]ssget [color=#2f4f4f]"X"[/color] [b][color=MAROON]([/color][/b]list [b][color=GREEN]([/color][/b]cons -4 [color=#2f4f4f]"<OR"[/color][b][color=GREEN])[/color][/b] [b][color=GREEN]([/color][/b]cons 0 [color=#2f4f4f]"DIMENSION"[/color][b][color=GREEN])[/color][/b] [b][color=GREEN]([/color][/b]cons 8 [color=#2f4f4f]"cab lines,text,drawing divider,splash,sqft"[/color][b][color=GREEN])[/color][/b] [b][color=GREEN]([/color][/b]cons -4 [color=#2f4f4f]"OR>"[/color][b][color=GREEN])[/color][/b][b][color=MAROON])[/color][/b][b][color=NAVY])[/color][/b][b][color=FUCHSIA])[/color][/b] [b][color=FUCHSIA]([/color][/b]command [color=#2f4f4f]"_.ERASE"[/color] ss [color=#2f4f4f]""[/color][b][color=FUCHSIA])[/color][/b][b][color=BLACK])[/color][/b] -David Quote Link to comment Share on other sites More sharing options...
