Open explorer in the current open drawing directory

This simple routine has saved me so much time. I work with explorer primarily to navigate through projects. However, I don't use it to open drawings. I work in LDT and we should all know its limitations by now when it comes to associating projects properly.

(defun c:expl () ;;Change "expl" to any command you wish for a macro
(startapp "explorer" (getvar "dwgprefix"))
(princ)
)

Copy the 4 lines above to a ASCII file with an extension of ".lsp". Loading is simple with the "appload" command. Add it to your start up suite and you're good to go!

Missing Icon Images on Toolbars (v2005)

This topic probably has been exhausted over the years but I have a tidbit to add to the mix for AutoCAD 2005. I updated a menu (.mnu) file and recompiled it. I opened my AutoCAD session and my icons were missing from my toolbars. Look familiar? ( ) I've done this a few hundred times and couldn't figure it out. I realized that the AutoCAD profile I had current didn't have any of my Support File Search Paths. The one I needed points to the location where I keep my bitmap files. I added that directory to my Search Paths and recompiled my menu and walla. It was found !

I get the task of working with the Custom User Interface (CUI) editor for our up and coming upgrade to 2007.
