Hi. Ive often had to manually calculate buoyancy by manually calculating the exterior volume of an assembly and then withdrawing the total weight of the assembly.

This works well on simple geometry, like tubes etc, but is not optimal for more complex shapes.

• Is there a better way of calculating buoyancy (or total external volume) of an assembly, where SW recognizes the closed cavity?
• Is there a simple way of calculating a closed cavity of a multibody part, like the example attached?

Thanks!
