volume calculation in a set

[Geppetto82]

Bye to all,
I would like to calculate the volume present within 2 packages where bearings, endless screws and a gear are predisposed.
I have read several discussions already present in the forum in which it was said to extrude a solid in the expense of the area that you want to calculate.
but does not exist another faster method?
It would be a bit complicated to extrude a solid in my case.
thanks to all

to calculate a volume there must be physical geometry by force of things.

Can't you do some Boolean subtraction? I was looking for the command in solidworks but I can't find it (I'm still novice).

If you're part of it, it's matched, which carries out boolean operations between the bodies of a multibody.
If you're in the field together there's the cavity command, which allows you to "dig" from a solid the selected parts as a tool.
in the latter case it is enough to make a cube that contains all the assemblies and subtract the various parts. the difference between volume preceding the cavity and subsequently to it is the volume sought. If you are struggling to find the volume by hand, or you need a solid that "reply" the colume (maybe to find, with due approximations, mass center and other physical properties, such as oil volume weight of a filled carter not totally), just go into the part of the "cubone" and with the combined command subtract from a "cubone" equal the one obtained by cavity.

conceptually it looks heavy all this "sopter-add" but don't worry: if you make prototype silicone molds or plastics of these steps there are many!! !

ok until here I am....but how do I create the solid of the "empty" that is between the two packs of the engine excluding the components that form it?

I've seen your answer, but now I've written... I'm meditating...

the cavity function works!! !
I did it a bit, but I finally did it!
Thanks oldwarper!
