When I calculate the mass properties for my assembly I get an incorrect mass. I've traced the problem back to the fact that everything is in the default Pro/E units (in lbm sec) except one purchased component where the system of units is (mm kg sec). Pro/E is rolling up this assembly's total mass using the component's mass value in kg as if it's lbm.
How do I correct this behavior? Thanks.
Yes, that's one way to solve the problem. But here's why that's not a preferred solution:
Am I missing something? Pro/E knows the system of units the part & assembly are in. It knows the conversion factors between units. Surely it can be made to do the conversion itself when calculating the mass properties of assemblies with mixed units?
Another thing to check is to see if alternate mass properties have been assigned to the part. One thing that will happen is the mass of the assembly will be calculated in the assembly units but the mass displayed and used for the part in the assembly list will be incorrect. If you are using PRO_MP_MASS it will display the value using the alternate mass properties.
It turned out the error was only visible when looking at the mass properties in Intralink. The values were all correct in Pro/E. I regenerated the Pro/E model, checked it in to Intralink Commonspace, & now the values are correct both places.
Thanks for the suggestions.
