How to draw a center of gravity point?

A - answer You can find and display the coordinates of the center of gravity (CG/COG) of a closed region or solid with the AutoCAD command MASSPROP. But if you want to draw the center of gravity as an entity, use the utility CADstudio Centroid.

The LISP application Centroid calculates and creates (as a POINT object) the center of gravity (centroid) of any closed polyline (pline), 2D region or 3D solid. Load it with APPLOAD and run the CENTROID command.

The free utility Centroid can be downloaded from

Since AutoCAD 2016 you can also use the osnap mode "geometric center" to snap to the center of gravity of an object - e.g. in the POINT command.
