Hi,
I'm trying to subtract small objects from big object but once I do that there are no sides created where objects were touching.
So model will become open as walls are missing.
I think it's very simple boolean diff operation but for some reason SW just don't behave like one would expect.

It's things like these that makes me sometimes curse at night.
I design something for hours and then spend 90 minutes trying to figure out why MOI doesn't do simple thing properly.

Can anyone explain to me what is the deal with this?
Thanks a lot.
