I am trying to reduce the rebuild time & memory usage for an asssembly.

To acheive this I have created 1 part with few multi bodies in it. This part is an replica of a sub assembly that I actually want in my assembly & the multi bodies are to represent child parts of that sub assembly.

The geometry I am getting in the drawing is exactly same as that I would get if I had done it with actual sub assembly & its parts.

Can I save rebuild time & memory usage for an asssembly by this method?

I personally think this is a sloppy backdoor workaround. What happens if you have to update anything inside the subassembly/multibody part? Yes, this will speed up the software a little, but it also limits you in several ways. If you can live with the limitations, then you may be ok.

I would investigate other methods first, such as lightweight and SpeedPak.

  I agree with Matt- another problem that using multi-body parts (instead of assemblies) is it limits you on your options within the drawings. You won't have the same visibility options for your views with multi-body parts as you have with assembies.

    I have heard that saving the assembly as multi-body will INCREASE rebuilt time. I haven't actually tested it though.
    
    Other disadvantages of the multibody setup would be no exploded view or accurate CAD driven BOM.
