I created a family for all the chairs I am using in our projects, I made it in one floor based family (since the buildings I am working have several levels on the same floor.
This is cca 25 unshared generic family in one family. it is 13 MB. when I load this into a new project file (2MB) that gets bloated up to more than 110MB.
What did I do wrong or what can I do?

Thanks in advance, Richard
