I have an arena that I am working on.  It has approx. 3500 seats in a bowl around an Ice surface.

I have created a fairly simple seat family, a "riser" family, and a simple step family. Images attached.

The seat family has 3 nested families. The riser family does have some parameters in it.  The rest have no parameters.

I have pulled these three generic models into a generic family called arena bowl.  *image attached.   Working in this family is a breeze, it's quick, nothing seems to bog it down.  The problems occurs when I try to pull this family into a project (or another family)

The insert takes 10 minutes or so, and it seems to subsequently bog the entire model down.  BTW, the model file without the seats is speedy, no issues)

I have checked to make sure none of the nested models are hosted.   I tried using groups initially, each quantity of seats in a row had a corresponding group.  That's when I noticed the initial slowdown.   So I ungrouped all the seats, still bogging down.  I thought maybe another nested level might help, so I tried putting the arena seats family into a new generic model, again it took a tremendous amount of time to pull the family in, and once in I couldn't navigate around the family very easily. 

Am I missing something here?   I though a nested families within families was the way to go?

Ultimately I would like to create the seats in a separate project and reference it into the working model.

Admittedly I am fairly new to revit, but I feel I have a pretty good handle on the program and content creation.   

Any guidance would be greatly appreciated.

Not enough information.

The problem could be your seat family or it could be your placement process or a combination of both.  

Why nested families in the seat?  It looks pretty simple.  Excessive ref lines/planes/locks can all slow down a family.  Post the family so someone can look at that.

Why did you "...I have pulled these three generic models into a generic family called arena bowl..."?  I would have thought the families are placed in the model.

It does sound like you learned some things about groups.  I don't see any reason to group anything here.

You have a lot of geometry happening here and you may have to live with some slow down but maybe not all the time.  We often use 2-1/2D families where we have heavy geometry like yours (all those curves),   By 2 1/2D I mean a family where the 3D elements only show in 3D views.  In plan / elevation and section views (section and elevation are normal), the item only has symbollic linework.

Thanks for the reply.   

No particular reason for nesting the seat components.  It was a method that was spelled out in an online tutorial.

The seating bowl (risers) family itself does have several parameters and ref planes used to control voids to cut out the openings.   I will simplify that and see if it helps.

I understand the 2 1/2D concept, I use that on several other familes and will likely use that here too.

My pupose for nesting the seats, riser and steps into a family was simply to try and minimize the footprint of the seats in the model.  This family is attached. My understanding was that nesting families within families was a method to do that. (perhaps I am wrong?)

I have inserted the Arena Seating family into a new project, then linked that into my model.  This seems to work pretty well.  Although I just noticed the Arena Seating Family is 2.8 mgb.  When I load just that family into a clean blank project (3 mgb), the project size balloons to 61 mgb.  Herein lies the problem, certainly, I just can't figure out why.

Thanks again for the assistance.
