(OP)
Hope this question isn't too basic for this forum.  This is my first try here.  

How do you calculate acreage with Softdesk/AutoCAD?

Thank you.

RE: calculate acreage

You can use the area command to get the square footage then just divide i.e.

sq_ft / sq_ft_per_acre

Or try this....

draw a closed polyline around the area you want calculated then use this command to calculate acreage....

;;; begin cut here
(defun C:acreage( / acres oce )
 (setq oce (getvar "cmdecho"))
 (setvar "cmdecho" 0)
 (princ "\nSelect closed polygon: ")
 (command "area" "E" pause)
 (setq acres (cvunit (getvar "area") "square inches" "acres"))
 (princ "\n")
 (princ acres)
 (princ " acres")
 (setvar "cmdecho" oce)
 (princ)
)
;;; end cut here


Thats all folks....

RE: calculate acreage

Striker's routine appears to assume drawing is in 'inch' units.  Drawings where acres are of interest may well be in 'feet' units.  If so, edit the routine to use "square feet" instead of "square inches".  Hopefully Striker will jump in if I'm in error...or try it out and verify it's working properly.

RE: calculate acreage

Thank you both for your help.  I just used the area approach, but have printed out the other way to try again.  I couldn't "translate" what it all meant.
