How to add mass to a point

I have a 3D frame model and I want to add mass to a point to locate the CG of a component.  The Help section says to use the Refine Model --> Mass function to do this, but I haven't been able to locate that function on the Ribbon, or in any of the Toolbars.  Where is this located?

The article you linked is referencing the Simulate application. This is used for FEA.

    Bummer.  Unfortunately, I don't have Simulate.  I didn't realize that's where I was copying the link from.  Thanks for the quick reply.

    I think this is relevant to what you are asking about.

     

    Article - CS60265 - How to assign user defined mass properties for a model, part or assembly, in Creo Parametric (ptc.com)

      This pointed me in the right direction.  Thanks.  I was trying to assign mass to a datum point, but apparently I can't do that.  I tried to create just a point in a sketch and assign mass to that.  I can't finish the sketch, because it's just a point.  So I created a sphere and assigned the mass to that.  Then I'll locate the masses in the assembly to give the total package the necessary weight distribution.

       

      Thanks for the help.

      You can do that by overwriting the mass property values out of the box without extra geometry.

      Just study the parameter box for alternate mass prop values. Change pro mp source to parameters. This alternate properties are used for calculation if used in other assemblies as well.

       

      Oh sorry Yes, the former answer points to an article, the same direction of using this.
