how to measure the area of a polygon

hazzer over 10 years ago

Hello - is there a ULP to measure the area of a polygon? I need the area to calculate the capacitance of a PCB capacitor.

Regards

It should'nt be hard to write one using this formula with the polygon's
contours() loop member.

Remember to subtract the holes. The contours() gives you access to the
holes too.

Also be aware If the opposite pole of the fill has holes underneath. Thats a
bit harder to calculate, but not impossible.
