Revit Model Maintenance Tips-n-Tricks 2013
Hardware Consistency
Attempt to get project participants on the same Windows Operating System (OS).
Windows Vista and Windows XP users working alongside Windows 7 users in a Revit model have caused problems before.  (SMB issues)
Windows Vista and XP are not supported for Revit 2014.
I haven’t seen Windows 8 cause issues yet, but it’s certainly possible.
Worksharing Update Frequency

Dial back  your worksharing update frequency.  This is in the Options > General dialog.  When working with a cloud-hosted model or a model over a WAN, dial this all the way back to manual.  That way graphic updates are only shown upon a sync with the central file and thus it reduces some network traffic.

Managing Revit and CAD Links

Check and double check that all linked CAD and Revit files in every file are linked with a relative path.  
Do not link using UNC paths
Use Drive Letter Mapping (ie: L:/)  for all links
We recommend all firms keep all of their Revit files within the same Revit folder so that relative pathing is simple and always works. 
Common file naming here is very helpful. 

Worksets and Revit and CAD Links

Place all linked Revit models on their own individual worksets.  Ie: Link-Structural Model, Link-Electrical Model, Etc.. 
Place all linked CAD files on their own workset(s), or even better, within a linked Revit model. 

When the workset is unloaded/closed, it removes the linked file from RAM and thus from communicating across the WAN.  This alone should dramatically increase each users workflow.
Make sure all users are on the same build of Revit.  A single user with the wrong service pack in place can potentially cause the same issues to be introduced back into a file, causing a vicious cycle.
This currently should be:
Revit Builds, Updates and Service Packs
Revit 2014 SP1
Revit 2013 SP3
Revit 2012 SP2

You're having issues with accessing your Revit model over a Wide Area Network (WAN)
While WAN file sharing is a little different than common local workflows and is easy to point the finger at if difficulties arise, Revit model management is to blame for many of the problems.
So let's figure out how to rise above the clouds.
Q & A
You've got questions.........
......We've got answers.
Forcing Workset Specifying on Open
Resave the file as a new central file.  When doing so, go into the Options in the “Save As” dialogue and change the Open Workset Default to “Specify” as shown in the image below. 
Creating New Local Files
and Opening Them
Users should be creating new locals from the central each day. 
Do not use the shortcut in the “Recent Projects” dialogue. 
Each time a user creates a new local file, they will then be prompted to open or close each workset as shown below. 
This will offer you the opportunity to close unnecessary worksets and linked files on those worksets. 
This will also speed up loading the file, especially to a cloud-hosted central model. 
Additionally, this helps to pinpoint if linked files are causing a corruption or hang-up in saving.

Synching with Central Files
When synching with central, use the default “Startup View” which should be set to a drafting view. 
Close all hidden windows before synching. 
The less views you have open, the quicker Revit will save.  This not only quickens your save time, but also the time available for others to save. 

Compact Central Files
Compact each file on a weekly basis. 
This can sometimes reduce file size by 1/3 and should be done when others are out of the file.
Any evening or early morning is usually a good time to do this. 
It is very important that users are creating new locals each time, otherwise this isn’t effective, as local file history is loaded right back into the central.
Imported CAD Files
Lookout for large CAD files from Civil Engineers and other consultants.  They typically have very large extents, and Revit can often have difficulty loading them.  Trim them down to what’s necessary for your work before linking in. 
When CAD files are imported, they are the culprit for corrupting Revit files the majority of the time.  Often, these are CAD files nested into Revit families, so they can be difficult to find.  Stay away from families that you see with embedded .dwg or .dgn.  Furniture is a typical offender. 
Large regions of hatch patterns can get nasty.
File Cleanup
Remove unnecessary views
There are often a series of "Working" views that can be removed from the project
Create a "View List" to manage these views and identify which views are not on sheets
You may also use the Project Browser setting for "Not on Sheets" to find views not currently on sheets

File Cleanup
Purge Unused
This may need to be done 3-4 times to get rid of nested materials.
This will also get rid of hidden object styles within unused families
Delete rogue objects that are far from the project origin.
