Delete Key...

Hi,

I was working in AutoCAD MAP today and some how my delete key stopped erasing objects from my drawing. I tried to set it up in the CUI but no luck. Anyone know how to get it to work again?

Thanks,

Restart AutoCAD and/or restart your computer.

Set PICKFIRST to 1

Wow, this is getting ridiculous. We really need to post my signature at the top of every forum section.

Mandatory popup: "Welcome to CADTutor: FILEDIA = 1, PICKFIRST = 1, PICKADD = 1"

Here's a reactor to solve the entire issue.

;;; FileDia, PickFirst, PickAdd System Variable Reactor
;;; Always reset FileDia, PickFirst & PickAdd variables to 1, if changed.

(or SysvarReactor
   (setq SysvarReactor
          (vlr-sysvar-reactor
            nil
            '((:vlr-sysvarchanged . React:SysvarFix))
          ) ;_ vlr-sysvar-reactor
   ) ;_ setq
) ;_ or

(defun React:SysvarFix (Call Callback)

1. Save above contents in Notepad as "SysvarReactor.lsp"
   
2. Place file in AutoCad Support Path.
   
3. Either add file to Startup Suite in AppLoad (little briefcase) or add the following line to acaddoc.lsp file: (load "SysvarReactor.lsp" nil)

Alan,

What prevents that reactor from calling itself in a recursive loop? When you change the SysVar in the call-back, surely the reactor event is triggered?

Can't believe I overlooked that...

Thanks all for the Help, When i posted this thread i noticed that the answer to my question was on another post... Pickfirst = 1

Where can i find a list of all the commands such as pickfirst = 1 in case something weird like that happens again.

They're not commands, they're variables, and 3 of the most common troublemakers are in my signature below.

You can find a listing of all Autocad variables, and a description of what they do, by typing SYSVDLG at the command line. Or go to your "Express" menu > Tools > System Variable Editor.

Another reference here for those who are interested - I find it easier to use than the one in ACAD, but of course, each reference is version specific so bear in mind that this one is for '06.
