Component—Center of Mass Quantities
If you choose Center of Mass as the measure quantity, your selections are the same as those for rotations and displacements. However, the software calculates the measure in terms of overall distance or distance in a particular coordinate direction.
For magnitude, Creo Simulate calculates the distance from the current coordinate system to the center of mass.
If you select one of the coordinate directions instead, Creo Simulate calculates the distance from the origin of the current coordinate system to the center of mass for the selected direction only. For example, if you select X as the component, the software calculates the distance between the coordinate system and center of mass in the X direction.
