Problem with automatic .plt LISP lineweight

Hello everyone,

recently I edited a simple routine to automatically generate .pdf files in both monochrome and coloured plot styles; currently I've been trying to create a routine for .plt files - the problem: the routine is running fine with the window selection, paper size center, etc. until it asks me the following:

"Plot with lineweights? [Y/N]" - my answer is "Y" as I do want to keep the lineweights.

"Scale lineweights with plot scale? [Y/N]" - not sure, I had it set to "Y".

This is my routine:

(defun c:plttest (/ fl)
(setq fl (strcat (getvar "dwgprefix") (getvar "dwgname")))
(setq fl (strcat (vl-string-right-trim ".dwg" fl) "-" (getvar "ctab") ".pdf"))
(if (findfile fl)
 (command "-plot" "Y" ""  "HP Officejet Pro 8600 (Rede)" "A4" "I" "L" "N"
      "W" pause pause "F" "C" "Y" "Monochrome.ctb" [color="red"][b]"Y"[/b][/color] "" [color="red"][b]"Y"[/b][/color] "" "Y" "" "Y" "")
 (command "-plot" "Y" ""  "HP Officejet Pro 8600 (Rede)" "A4" "I" "L" "N"
      "W" pause pause "F" "C" "Y" "Monochrome.ctb" [color="red"][b]"Y"[/b][/color] "" [color="red"][b]"Y"[/b][/color] "" "Y" "" "Y" "")
 );if

Enter plot offset (x,y) or

Have you checked the monochrome line weights using the ctb will override your line settings

my settings no probs
