Just don't build it in-place or you'll hurt your processing speed.

"I seriously hope he's not worried about 150k. The friend that I reference had a 9GB family drop to 3GB. Now that's a chunk of file-size worth spending a few moments to recover." Well, im’ my case I could have 100's of these families so if I can reduce file size on each 1 then I make the main file more workable for the other guys. Every little bit helps. It’s pretty stupid not to make your families economical.

There is a dead horse kicking here... Back to the topic, Families -if properly created- have objects, masses and geometries that relate to a skeleton of reference planes that may be tied to parameters, which help you make family types. They also include reference walls/floors/faces/etc. for insertion, and they have an origin point and all sorts of relative constraints and stuff in them... that makes them "flexible" unlike Autocad blocks or Revit groups that is just a bunch of objects in a certain array. If you were to explode them, all the skeleton, parameters, relative constraints and family types would make no sense in the project, and all the objects that make the family wouldn't have anything to relate to. Making it imposible to create the family.

There's got to be a point of diminishing returns...BUT, if you actually have hundreds (plural) of families that: A. ...are so important that they need to be in your template (main file?) B. ...are so important that the parametrics are worth rebuilding OR not so important that they are worth tossing. C. ...aren't time-sensitive (model changes, new products, etc.) so the process isn't cyclical D. ...you are willing to take weeks to manual-explode them through every nested tier individually. ...well, then more power to you. Just remember when you are determining how "economical" this is, that you don't forget the "cost" part of a cost-benefit analysis. Every case/person/project/office is different, so what I said may not apply to you, but just because my point was expressed flippantly, doesn't mean it wasn't valid.

I agree with you Bauhaus1919 All my families that I have build are future proof in regards to model changes etc and have multiple family types and parameters. To be honest I’m a newbie that Revit but I’m an old hat at very large projects so I always look at the bigger picture in regards to file workability. Generally its the Revit manage who gets kicked in the teeth if the files are so chunky that they are difficult to work with - which is why I wanted to reduce file sizes. In our case we have set up multiple template files for each of our larger clients with all relevant families loaded in – but even then this could total 200+ families. In this case we are testing separating our fixture families out into a separate file then just link it in. We are still in discussions whether we go back and change the majority of our families that are used in a large multi-level retail project to be non-nested families to ensure the central file is manageable – but as you said this could take weeks. Finally, I join these forums to get ideas of other Revit users. Obviously there is not a single right way of constructing families etc within Revit – I suppose you go with the method that works for you. I personally value every1’s opinions and ideas as a method of education. Cheers

I think the problem when people talk about "speed" in revit that they aren't really defining what they need. Im completely guessing on some of this but i've been using revit for a while and If im wrong please correct. 1. Save to central speed. This is slowed down by adding large families, more views etc, but if the familiy is already in the file then I don't see how it would slow things down. It seems that the more project errors and changes matter more for save to central then actual family sizes. 2. processing speed. This is affected by the number of links/parameters/etc that have to be calculated in order for revit to do anything. i.e. if a hundred floors are attached that that wall you are moving then revit has to recalculate all those floors too. 3. screen refresh speed. affected by file size, poly counts, and computer hardware. This is where if you have curved surfaces with billions of polys in 3-d then your graphics card is working pretty curse hard to refresh the screen and your processor is bogging down pretty hard trying to feed it.

Solved!
I made a short video on how to import Project Files from Revit into other Revit Projects. See link below!

Additionally, you can edit family files for 3D purposes, but it you wanted to rework the linkwork in 2D- I recommend using a clipping mask and detail lines to show the relationships (on lets say a construction detail) correctly. In this case no explosion is necesarry. Video on this below:

Enjoy!

I would like a Box link to that 3GB family when it is done.
