Hi Chris,

It does, but it's hard to quantify it exactly because it depends on a lot of different factors.

Object count is not particularly indicative of complexity all on its own. For example 600 boxes is not very complicated but 600 solids with a thousand surfaces in each object could be pushing it.

You can get a total face count by selecting everything and pushing "Details..." - there will be a total face count shown here:



It looks like you've got a substantial amount of very tiny fillets:



That's probably the main thing bogging things down.

What is the size of the print going to be, is there going to be enough resolution to be able to even see those tiny fillets?

Another thing you could experiment with is to divide some of the heavy objects into separate pieces.
