I model rotationally moulded plastic parts from which a single moulding can give rise to many subcomponents. To create these subcomponents I can specify splitting tools that create solid bodies: but only on relatively simple models.
When splitting tools become more complex, trying to modify the model during the development process can lead to lengthy repair time on those tools. I thus find it more robust to remove many small lumps from the moulded part until there are many resultant subcomponents 'floating in space'. At this point I would like to be able promote these unattached 'Lumps' into 'Solid Bodies' which I can then easily spit out into an assembly.
