adding increment number to lisp

Recommended Posts

alat

you helped me before with one lisp, i am trying to do the same thing to another lisp but with no success.

my original post

http://www.cadtutor.net/forum/showth...g-to-area-text

 

my goal is the same like my first post, to add increment number in the text, next to the "L" letter

the lisp i want to change:

;;  This program allows a user to generate a field expression           ;;
;;  referencing the length/perimeter/circumference of one or more       ;;
;;  selected objects. In the case of selecting multiple objects, the    ;;
;;  field expression will reference the sum of the lengths of all       ;;
;;  objects in the selection.                                           ;;
;;                                                                      ;;
;;  The user may opt to specify a point at which to create a new        ;;
;;  multiline text object housing the field expression, pick a table    ;;
;;  cell in which the field should be inserted, or select an existing   ;;
;;  single-line text, multiline text, multileader, or attribute to      ;;
;;  be populated with the field expression.                             ;;
;;                                                                      ;;
;;  Upon issuing the command syntax 'LF' (Length Field) at the AutoCAD  ;;
;;  command-line, the program first prompts the user to make a          ;;
;;  selection of objects for which to return the length summation.      ;;
;;                                                                      ;;
;;  At this prompt, the user may select any number of Arcs, Circles,    ;;
;;  Lines, 2D Polylines (light or heavy), or 3D Polylines.              ;;
;;                                                                      ;;
;;  The user is then prompted to specify a point or table cell to       ;;
;;  insert a field expression referencing the summation of the lengths  ;;
;;  of the selected objects.                                            ;;
;;                                                                      ;;
;;  At this prompt, the user may also choose the 'Object' option in     ;;
;;  order to populate the content of an existing annotation object      ;;
;;  with the field expression.                                          ;;
;;                                                                      ;;
;;  Upon choosing this option, the user may select any single-line      ;;
;;  text (DText), multiline text (MText), single-line or multiline      ;;
;;  attribute, attributed block, or multileader (MLeader) with either   ;;
;;  multiline text or attributed block content.                         ;;
;;                                                                      ;;
;;  If the user selects an attributed block or attributed multileader   ;;
;;  with more than one attribute, the user is presented with a dialog   ;;
;;  interface listing the available attributes, and is prompted to      ;;
;;  select a destination for the field expression.                      ;;
;;                                                                      ;;
;;  The user may optionally predefine the target block/multileader      ;;
;;  attribute by specifying the attribute tag where noted at the top    ;;
;;  of the program source code.                                         ;;

;;  The resulting field expression will display the sum of the lengths  ;;
;;  of the selected objects, formatted using the field formatting code  ;;
;;  specified at the top of the program.                                ;;

What my function increment does, is replace a * character in the pattern by the number you want.

 

So you have to put a * somewhere in this string:

 

(setq fmt "L=%lu6%pr2 cm" ;; Field Formatting

 

And of course you have to close every bracket that you open.

The error message that you are getting now is a syntax error, telling you that Autocad refuses to load the script (as long as the brackets don't match).

 

 

Try this:

(setq fmt "L*=%lu6%pr2 cm") ;; Field Formatting

Ah, the closing bracket had moved to to the next line.

 

Make sure it's like this:

   (setq fmt "L*=%lu6%pr2 cm") ;; Field Formatting
   (setq 
         fmt (increment fmt)
         tag nil    ;; Optional predefined attribute tag
   )
