Calculate area in Meter Square 

This lisp is used to Calculate the area of an object in square feet.

1. Please Edit it to calculate in Square meter.
2. Please Edit it to calculate for multiple objects.


;;; AreaText.LSP ver 3.0
;;; Command name is AT
;;; Select a polyline and where to place the text
;;; Sample result: 2888.89 SQ. FT.
;;; As this is a FIELD it is updated based on the FIELDEVAL

Just be careful if you have some more complex shapes (typically "C" shape) -- label may be outside the closed area.

It's not written to do that.  Curiously, your original code describes itself as only for Polylines, but in fact works on other entity types, too [even Lines! -- it puts 0.00 in for the area].

 

Here is one that reports in square meters.  But it also says it's just for Polylines.  Maybe you can easily take the part of it that determines the text content and transfer that into your code in Post 1 [and change the description in that, to not be in terms of only Polylines].

@gpcattaneo, I must admit I'm impressed!! Nice solution!

 

 

-- haven't dig into algorithm much -- do you somehow test if a text is really inside?

 

I tried a little test... not really hard, these are the only shapes I've drawn...

Fantastic, Gian!!

 

It will be better if the texts were as a field. Smiley Happy

@ВeekeeCZ

Increase the value of "step1" on very narrow polygons.
