Hello all,

I'm currently designing what is probably my most complex prototype thus far with 15 seperate loose cores.

I have them all modeled seperately but with same origin and in the assembly each one has a seperate cavity cut and then the cut outs in the main plates are referencing all these loose cores.

Trouble is there is so many different references to each part that rebuild times and just in general it is causing solidworks to hang for 20 or so seconds each time i try to do a feature or mate a component.

So my question is, when doing a tool such as with numerous cavity cut components what is the best practise, to have one part with multiple bodies ?
