AutoCAD does have a single “Centroid” button, but you can extract it reliably using several methods.
Why go through this trouble? The centroid is rarely just a dot on a screen; it is an anchor for design logic. polygon centroids autocad
This is the most accurate method, as it computes the true centroid based on area. AutoCAD does have a single “Centroid” button, but
Load the LISP, type CENTROID , and extract coordinates automatically. This is the most accurate method, as it
Always ensure you are in the WCS before extracting coordinates to avoid confusion with skewed UCS angles.

If a polygon crosses over itself (like a figure eight), AutoCAD cannot calculate a single centroid. You must trim and join the shape into clean boundaries.
