Center of mass relative to WCS

[Kraig66]

I'm a new NX user (version 12) after several years on Solidworks. I'm trying to find the center of mass of an assembly arrangement relative to the WCS. I set the WCS at a rotation axis. When I run the Advanced Weight Management / Work Part command, the results only show Center of Mass relative to a datum coordinate system (Xcbar, Ycbar, Zcbar).
What am I missing? Is there another way to do this?
Also, What does cbar represent?

Thank you.

There's an option to create a Point object at the center of Mass. Once created, you can easily find, using the Info function, the location of the Point object relative to both Absolute CSYS and WCS.

XC, YC, and ZC refer to the Work Coordinate System (WCS). It seems you already have what you were looking for.

The letter X with a short horizontal line above it (commonly pronounced X bar) denotes the average value. When you take the average weight over the X, Y, and Z directions, you end up with the center of gravity (X bar, Y bar, Z bar). I guess that NX spells out "bar" in the information window because it probably doesn't have the X bar character in the font it uses.

Thank you. Yes, it turns out I did have what I was looking for.
What is the command sequence for creating a point at the center of mass?

Someplace in the menu is the 'Associate' option that must be toggled toggled ON.
If you don't see make sure everything is expanded.

This article has several videos to help explain the new measure tool (new as of NX 12). In the video for #11, it shows how to create geometry associated with the measure feature. The video creates a line along the minimum distance vector for a linear distance measurement, but the process is the same for creating a point at the COG of the selected body or bodies.
