Get Mass Properties using IMassProperty (VBA)

This example show how to get the mass of the selected component of an assembly.




' Preconditions:

' 1. Specified assembly document exists.

' 2. Open the Immediate window.

' 3. Run the macro.


' Postconditions: Mass of the selected component printed to
' Immediate window.
