Change fonts in text style and line thickness in all layer from command line?

As per subject line:

1. Need to change fonts in one of customer text style to make it readable on print and

2. Line thickness in all layer to 0.

Looks like got only last line of my script for print previous

1.missing
2. missing
(command "-plot" "no" "" "previous plot" "" "" "" "")

Please...

What's the font's name and the text style that you want to change them to ?

for changing all layers to 0. ( line Weight ) follow this simple process .

Command: [b]-la[/b]
-LAYER
Current layer:  "0"
Enter an option 
[?/Make/Set/New/Rename/ON/OFF/Color/Ltype/LWeight/MATerial/Plot/Freeze/Thaw/LOck
/Unlock/stAte/Description/rEconcile]: [b]lw[/b]

Enter lineweight (0.0mm - 2.11mm): [b]0[/b]

Enter name list of layers(s) for lineweight 0.00mm <0>: [b]*[/b]
Enter an option 
[?/Make/Set/New/Rename/ON/OFF/Color/Ltype/LWeight/MATerial/Plot/Freeze/Thaw/LOck

Text style is RDM, fonts: romand to romans

How do I can create command to change it without open dialog box

Same to: all layers line thickness to zero.

This routine would change the text style RDM font name to romans , and for lines you can follow the above process that I brought earlier .

(defun c:Test (/ sty)
 (vl-load-com)
 ;; Tharwat 25. 10. 2011
 (if (tblsearch "STYLE" "RDM")
   (progn
     (setq sty (entget (tblobjname "STYLE" "RDM")))
     (if (not (eq (cdr (assoc 3 sty)) "romans.shx"))
       (entmod (subst (cons 3 "romans.shx") (assoc 3 sty) sty))
     )
     (vla-regen (vla-get-ActiveDocument (vlax-get-acad-object))
                acAllViewports
     )
   )
 )
 (princ)
)

Will try.

Thank you Tharwat.

You should be able to alter the style with the -STYLE command.

Ok got text style done, Now how to change all layers line thickness in one hit to 0.0 thickness.

All dwgs got variable number of layers, cannot fix it with script... any macro but without dialog box?

My head is empty now but almost 200 dwgs to print.

Done with old script - just added to acad.lsp and work OK.
