But since you're given the curves bounding the area, you would be better off writing the area integrations as line integrals along the . You can also use the Brep Volume (Surface>Analysis>m3) for the center of a volume.try a boolean union of all the solids and the volume of that should give . That just conveniently happened to be the max y-value of the perimeter, and the initial step ought to be perpendicular to the curve at that point (I think it mathematically has to, but are too lazy to prove this) - therefore it should be in the downward . Hi rcpomp, I wasn't sure if you wanted his to be a function or a subroutine. The centroid of a function is effectively its center of mass since it has uniform density and the terms "centroid" and "center of mass" can be used interchangeably.
