Do 'Edit>Setup>Mass Props'. In the 'Source' selection window, pick
Geometry
and Parameters. Under actions, pick Edit. Fill in the Mass (your measured
weight) and Volume (which you get from 'Analysis>Model Analysis'). Then
click Generate Re****t. You'll see the supplied mass and volume with a
calculated average density. When you do the analysis of the assembly that
this sub goes into, be sure to click Assign when it asks about how to deal
with the sub.
