area command problems

[Anonymous]

Does anyone have no of a fix for the area command change in 2010. I have
several programs that I use the Area command with that no longer work.
Plines that cross over themselves are ignored, I use the area command then
pull the Perimeter setvar to get the length in several programs.
I know that I can use VL functions to in place of the area command for this
purpose but I don't have time right now to go thru the learning curve.

Thanks

Try
command "LENGTHEN"
then
getvar "perimeter"

Hi,
This subject was diiscussed here recently and there's Tony's solution which
can be used without necessarely going to the learning curve, at least not
right now:

;;;=============================
(defun c:getarea ( / try-get-property ent area)

(vl-load-com)

;;;-------------------------------------
;;;The next function is by Tony Tanzillo
;;;-------------------------------------
(defun try-get-property (obj prop / result)
(vl-catch-all-apply
(function
(lambda ()
(setq result
(vlax-get-property obj prop)
)
)
)
)
result
)

(if (setq ent (car (entsel "\nSelect hatch: ")))
(if (= (cdr (assoc 0 (entget ent))) "HATCH")
(if
(setq area
(try-get-property
(vlax-ename->vla-object ent)
'Area
)
)
(princ (strcat "\nArea is " (rtos area)))
(princ "\nHatch has no area.")
)
(princ "\nSelection was not a hatch.")
)
(princ "\nNothing selected.")
)
(princ)
)
;;;=============================
