Topic: Getting Area From Hatch Error

[GDF]

Ok, I sometimes get an error or crash using this code.
Yes, I'm stumped.

Here is another example for MP

Please help

Sorry, I forget this function:

Code: [Select]

;;;Victor Delgado  VDelgado@alhansen.com
(defun ARCH:UpdateBlocks  (BlockName AttTag AttVal / ssBlocks ssObjects Block)
  (vl-load-com)
  (setq ssBlocks (ssget "x" (list (cons 2 BlockName))))
  (if ssBlocks
    (progn (setq ssObjects
                  (vla-get-ActiveSelectionSet
                    (vla-get-ActiveDocument (vlax-get-acad-object))))
           (vlax-for
                  Block  ssObjects
             (foreach
                    Attribute  (vlax-invoke Block "GetAttributes")
               (if (= (vla-get-TagString Attribute) AttTag)
                 (vla-put-TextString Attribute AttVal))
               (vla-update Attribute)))))
  (princ))

(ARCH:UpdateBlocks "DRHortonTBH" "ADD" (vl-string-left-trim (substr (vl-filename-base (getvar "dwgname")) 1 16)
        (substr (getvar "dwgname") 1 (- (strlen (getvar "dwgname")) 27))))

Error message ?

[GDF]

Can't divide by 0.

Or it would just crash...

Here is an example of what I modified:

           (if (= tot_areabrk nil)(setq tot_areabrk 0))
           (if (= tot_areasid nil)(setq tot_areasid 0))
           (if (= tot_areastn nil)(setq tot_areastn 0))

It seems to be working now...just a crude example of code.
