Computing polygon area

RayA

Is there a feature in EAGLE, or a ULP, that can compute the area of a polygon in a non-copper layer? (Also, same question for copper layer, if it makes a difference.)

 

I want to do this so that I can measure how much board area was used for certain sections of an existing design, and use that number to help estimate how much board area will be required for a new design.

 

Thanks,

Ray

    That link just jumps back to this message string. You probably intended to link to this one: Area of a polygon algorithm - Math Open Reference.

    That's the formula that I mentioned previously, that you had sent to me when I was trying to compute board area. I had forgotten about it because It didn't work for me then, because my boards usually have curved outlines, but it should work for the polygons that I'm dealing with now.

    Now all I have to do is figure out how to get the coordinate date out of EAGLE in the correct format, and figure out how to run a Javascript.  Ha. I'll work on it.

     

    But it would be easier if it was in a ULP. Maybe this is my chance to learn how to write one.

    Thanks, Clem.
