Automated Plotting

[timlane]

I am running AutoCAD 2012 and have a lisp routine for plotting which I am having issues with. I am attempting to create a PDF file using the DWG to PDF plotter. I can create the PDF file just fine as long as it doen't already exist. If the PDF file exists then I get a message that the file is in use which it is not. Can you help me with this line of the program to fix this problem?

(command "-plot" "yes" "" "dwg to pdf.pc3" "arch D (36.00 x 24.00 inches)" "inches" "landscape" "no" "extents" "f" "0.25,0.375" "yes" "plotter mono 24x36.ctb" "yes" "no" "no" "no" "~" "no" "yes")

Try it with (setvar 'expert 5)

(defun RM:Find->Delete  (file)
  (if (setq file (findfile file))
    (vl-file-delete file)))

I have had this problem with windows 7 and having the viewing pane open in explorer. Try closing all open folders and replot.
