Intersection Area of 2 Polylines
« on: March 16, 2017, 09:38:48 AM »
Hi,

There are two Closed Polylines intersecting each other. I want area of intersection (i.e. area of overlapping). I dont want to create any common polyline or region, just need the common area. Please share if anyone has code for it.

Thanks.

I am not doing it manually but in LISP.
When i use BOUNDARY command, it asks for internal point.

How to know coordinates of any point in the Overlapping Area.

I don't have time to test or code anything up but maybe create a region for each polyline, then run "intersect" on them, then get the area property of the resulting region.
