I have a situation where someone want to use the base frame and make 10+ sub assy's. Each sub has the base in it. Then an overall assy that brings in each sub and mates the identical bases to each other, so you end up with 10+ bases in the o.a. (no way to get a c.g.)  My question is this... Does the base load 10 times into ram or just once in this scenario? When I pack&go to zip, the file is huge because of this.
