Center of Mass for Multiple Bodies/Components

[Anonymous]

I've just created a selection set of 3 components. When I right click and look at the properties I am being shown the mass of only a single component. Does the properties feature support selection sets or multiple entities? I can't tell if I'm looking at a bug, being dumb, or if this hasn't been implemented in Fusion. 

Just trying to find my center of mass to verify the balance of a quadcopter.

I tried this and I used the Combine tool to join all the components into one component, the COM then had a different coordinate value than when I selected one body before using the Combine tool.

I am not sure if it helps you but when the Combine tool is used it seems to group the bodies into one component, they are still individual components and can be selected individually when the component tree is expanded.

Clever workaround. I'll let you know if it works when I select ~80 components to join 😉

Aaaaaaand that workaround is a no go. My parts are a variety of materials. Aside from the fact that my computer had an aneurysm trying to combine so many components it converted them all to a single material. 

I usually just throw my parts into Solidworks to do anything smart with them after modeling but it's having trouble importing some of these components and I was hoping to get this aspect of work into Fusion. 

Any other ideas anyone?

Thanks for the help Cx2 🙂

I am having the same problem albeit much simpler. I wanted to find the center of mass for a hammer I'm designing but my handle material is different from the hammer material. 😕 Hoping someone figures this out.

When you toggle 'Center of mass' it asks for the bodies to calculate it.

this is pretty easy - just select both components in the Center of Mass analysis type.  It will take into account both components and their materials:

If you want the Center of Mass displayed correctly for an Assembly, simply start the command and select the top level assembly at the top of the Browser.  This will work correctly every time "if" your assembly is created correctly using components and joints.

Got it now...thanks!
