Topic: area in text

[ampm6170]

i need to find out the area of many rooms and show the area on the drawing. instead of plugging those numbers (areas) everytime by using TEXT , is there any other quicker way to do the numbering after checking the area?

thanks

Try this:

Code: [Select]

;Puts text with objects area in it unless it is 0.00*------Many thanks to the SWAMP.ORG for all the help

(defun c:rat (/ *error* u-clayer getboundingbox llc urc s1 index ent obj bbox mpt obj_area txt deltext a n)
(setq a 0)
(command ".undo" "begin")
   (command ".style" "arial" "arial" "" "" "" "" "" "")
   (prompt "\nARIAL is now the current text style")
(princ)

I say: FIELDS

Don't have a clue how to do that in lisp, but fields are so for this.
