Is there a straight forward way of doing this that I'm missing. If I right click on a polygon and select 'info' I can see the stats including the number of line segments the polygon is constructed of (borders). I would like to query this into a table for a very large number of polygons. --------- ...

Not ideal as had to do this for multiple end point heights but quicker than going down the api route for more accurate individual line ...
