C#.net how do I access the geometric center of a closed polyline?

[jeff.wangD95HG]

its the point that shows up once you turn on object snap -> geometric center on a closed polyline.

How do I gain access to referencing that point?

if not I am wondering about what is the algorithm they use to calculate that point. and its not as simple as take all the points and average them because the points distribution might be skewed on one side

Hi,

The GeometryExtension library provides a Polyline.Centroid() and a Polyline.Centroid2d() methods.

You can also get a method which uses the same algorithm in this reply.

thanks for the quick reply. this works. I used the region method in this reply.

The first one (GetPolylineCentroid) is much more faster.
