Mass moment of inertia in parameter

Mass moment of inertia in parameter

I have a part with abt 30 instances. now i need to find their mass moment of inertia. Is there any relation (jus like mp_cg_x), that i can add in relation and call in family table so that i'll get all the inertia values updated automatically in my family table???

Or Is there any way to find the moment of inertia without opening the instances individually???

You can do it, First open generic model go to file prepare model properties> mass properties> change> click on calculate and click ok.

Now, create a parameter let say "A" and type a relation A= (click on local parameters and select reported or extended reported mass properties. select desired moment of inertia value). Now create the family table and select the parameter "A" (I guess u know the selction methods). Keep * in the parameter field. Verify and regenrate the model. Reopen select the instanceces by column and click on "A" to see the inertia for differnet instances. Attaching example for your reference.

I able to retrive the inertia tensors, thank you..

Is there a way to do the same for Principle moments?
