ripuz Posted May 5, 2015 Share Posted May 5, 2015 Hi, I want to prevent a layer from being plotted and I have found a few ways to do this but which way is the best? 1. (command "_.-layer" "p" "n" "LAYERNAME" "") 2. (defun PlotLayer2 (layerName bool / en output) (if (setq en (tblobjname "LAYER" layerName)) (progn (entmod (subst (cons 290 (if bool 1 0)) (assoc 290 (entget en)) (entget en))) (setq output T) ) ) output ) 3. (defun PlotLayer3 (layerName bool / acadObj doc layers layer output) (setq acadObj (vlax-get-acad-object)) (setq doc (vla-get-activedocument acadObj)) (setq layers (vla-get-layers doc)) (setq layer (vl-catch-all-apply 'vla-item (list layers layerName))) (if (not (vl-catch-all-error-p layer)) (progn (vla-put-plottable layer (if bool :vlax-true :vlax-false)) (vlax-release-object layer) (setq output T) ) ) (mapcar 'vlax-release-object (list layers doc acadObj)) output ) I know that it doesn´t play a big role in this example, but which is the best programming technique theoretically? Is it needed to release the objects in PlotLayer3? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
