The Centroid utility calculates the centroid, or center of gravity, of a 2D shape. The utility shows the location of the centroid and can place a locus at that point. For more information, see Obtaining Engineering Properties.
To place a centroid locus point on an object:
Select the object.
Select the Centroid command from the appropriate menu:
● Architect workspace: AEC > Machine Design > Centroid
● Landmark workspace: Landmark > Machine Design > Centroid
● Spotlight workspace: Spotlight > Machine Design > Centroid
The Centroid dialog box opens.
The location of the centroid is displayed. Select Place locus at centroid to place a locus marker at the centroid of the object.
Click OK.
If the object is moved, the locus point does not remain centroidal unless the object and locus point are grouped and then moved.
