Any advice here would be appreciated.  Seems Revit is like carrying all your eggs in one basket.  We received a model from another Arch firm who does things a little different to the way we do things and to put a long story short we have also inherited some problems with a file.  Our electrical file is running at a super slow speed, I am talking 2 hours to open up, if we close all worksets it only takes a few minutes but as soon as we turn on the Architectural workset containing the Arch file it takes 30 to 60 minutes to even longer to switch views.  The electrical file is the only file experiencing this issue and the Arch model is running at normal speed and so are the other disciplines (all workable except for the electrical)  If I unload the arch model the elec file becomes workable but as one might guess, you can’t see the building.  We have spent 2 days researching, relinking, removing this, removing that, changing this and changing that.  I have come to the conclusion that I will have to rebuild this entire electrical model, re-setting up all the sheets, area plans, bring in the details etc…  This is my first true problem with a revit file and have discovered that when the file goes bad the whole thing goes bad, it's not like we can just recreate one sheet this is every sheet.

Any advice on how to rebuild an almost complete model with 100 + sheets and views.

Thanks

Thanks

* What is the size of the model files ?

How much RAM in the PCs ?

We have 24GB for our big models.

Does the slowness happen on all PCs ?

Are the Links on seperate worksets ?

* Are all linked in model files in the same folder and on the same server ?

Are all drives on all PCs mapped the exact same way?

Make sure you don't have multiple copies of the same Arch link in host Elec file.

Where did you get the electrical families from (lighting, security, power, data etc.)

Does the Arch model run slow when you link inthe Elec model ?

Also, make sure you control the VG of the architectural link in all your views.  Does it have a lot of CAD imports?  If so are they on worksets you can turn off in the link? Did you model the same elements as the architect's file?  If so, turn those off in the VG for the link.  You should only be seeing those items you need to see.

Hopefully you are NOT using linked views.

-  Arch Model size : 137,356KB  Elec model size : 60,144KB

-  6GB Ram

-  Slowness happens on all PC's

-  All Links are on seperate Worksets

-  All links are in the same folder

-  All drives are mapped the same way, we use a .bat for mapping

-  I didn't even think about a copy of a link but I have detached and reattached the link so logic would tell me that a copy would detach too but not 100% sure

-  Can't say where I got the file from, not trying to point fingers.

-  My problem is with the electrical model only, all other files run smooth and have the same arch model linked into them all

-  Some cad files linked in but not loaded and putting them on their own workset is a very good idea

-  Not sure if the same elements are modeled in the arch model, havn't spent much time in the arch model since it was only the elec having issues and all other discipline are running fine with the same arch model linked in.  I will check on this.

-  I don't understand "Hopfully you are not using Linked Views".. Do you mean under VG revit links Display Setting By Linked View?  If so we use this all the time what's wrong with using this feature?  but funny enough the one view I checked  is By Host.  Not sure about all the rest since it takes so long to switch views.

"We received a model from another Arch firm who does things a little different to the way we do things and to put a long story short we have also inherited some problems with a file. " This is the very reason for the current poll question.

This may not be the reason for your problem, but is one that is often over looked. Open the electrical model or all of them for that matter. Goto Manage>Inquiry>Warnings. I"ve send an over abundance of warning cripple some files when linked together in some cases. Just a thought, maybe it will help

Coreed, turns out there are thousands and mean thousands of warnings for each and I mean each central file.  I detached from central all central files and rebuilt the project off to the side so I can go delete crazy on the wanrings.  This of course deleted the elements too but allowed me to access other views, there are a ton of duplicated elements on top of each other. Also turns out that each room, hallway and anything surrounded by a wall had it's own plan region, each area plan has it's one section box, and a ca-billion copy monitors and referance planes.  The arch model, each room is its own model group equaling a hundred plus model groups.  I am sure I have left something out. So this is what I think is giving this project slow perfomance and could not imagine how the original design team that sent us these files didn't have the same perfomance issues as us.

Hubb, not a single calculation, the electrical was drafted in without any system tools used.  (thanks for pointing me in that direction)  I wouldn't have thought about it.

I am not saying this will be the end of my perfomace issue with this project so I maybe back for more advice but thanks for the helping hand so far.

Well, as much as I would like to blame the other guy.  I found the original files that we where given and they are in 2012 format, in 2012 the files work fine, even with all the crazy other stuff I found.  As soon as I upgrade it to 2013 the file goes to crap-ola.
