Assembly Pattern Mass Properties

I'm working on building a table of mass-properties for components in an assembly.

 

I am using assembly patterns for common hardware components, and I would like to obtain an aggregated mass properties for all the fasteners in a pattern (mass, CG, MOI etc)

 

My team-member is moving patterns into separate sub-assemblies to accomplish this (you are able to "activate" and thus isolate the parts as an assembly,) but that feels like quite the convoluted work-around and breaks up the logical organization of my model-tree.

 

Is there a direct way to pull the combined mass properties for a circular pattern of bolts?

 

Note: Some of the patterns are not symmetrical, and I'd prefer to avoid aggregating numbers manually.

 

Thanks in advance.

No need to do this manually. One way to do this is by using simplified reps in assembly mode and an analysis feature. See the video for details using a simple example. I have used a saved analysis and not a feature in the example. You can extend the automation and utility using features if you want to use the measurements in relations, notes etc.

 

Here you can see the mass properties update when a simplified rep is activated in assembly mode.
