Finding center of gravity

Is there a way for libreCAD to find the center of gravity of a part if it knows all the dimensions?
Is this a viable route of development?

Since LibreCAD focuses on 2d, a reasonable cog is also limited to 2d.

In the case of 2D it would be second moment of area instead of center of gravity. Multiplying by thickness and density gives weight which is centered at the center of second moment of the area.
