Assembly properties not including hidden components

BLDG_orange — Fri, 13 Feb 2015 16:35:54 GMT

It seems like the assembly properties (more specifically the weight) includes hidden components. Is there a way to get the assembly mass and not include certain components without deleting them? Also, how can I get the assembly center of mass?

Thanks!

Hi Tim,

As you have observed you need to do at least a "soft" delete to exclude those bodies or components from being calculated in the overall mass numbers. We don't have a way of classfying a type of component for exclusion in mass properties like, for instance, Autodesk Inventor which does phantom parts.

Unfortunately, at this time we don't do center of mass or mass moments of inertia calculations native in the product. We just give you the mass.

A workflow you might consider though to make exclusions for your mass calculations a bit quicker is to use soft deletion and selection sets. Soft deletes are a feature that shows up in the timeline. They can be suppressed and unsuppressed for actions done in the future (which might save some time)

If you grouped your excluded parts into a selection set that would make furture selections easier to exclude. Just reselect and unsupress the soft deletion feature.

Hope that helps a little.

Best,

Mike

Another thing you could do, is create a custom Physical Material with a 0 mass. I use that for machine tables/bases that I don't want calculated with my fixture weight/mass.
