Hey all, I need some serious help.
I am new to the Bentley infrastructure and having some major problems.
I have models supplied by our process engineers and our structural engineers. I have been shown how to create a project and reference these models.
I navigate with most of the references turned off.
Navigating the model takes an inordinate amount of time.
I get 20-40 crash/error report popups per day?
Where to I start to gain my sanity back?
Well it comes and goes. Honestly.
Usually I find the culprits that cause the crash or things just get fixed as I work.
Refs off should help but I would say that my models are quite large and that is probably more of the issue.
Try little tricks like running as an administrator. Make sure things are broken down into chunks of data. don't break them down just to break them down but there are logical ways that need to be broken down like. Stairs, first floor, 2nd floor, roof, exterior walls, etc.
If you find a file that repeatedly crashes then copy it and start deleting things until you find the culprit. Or create a blank ad add stuff until it crashes. Last project I had it was quick made trusses that the structural stuff wont make.
When I made solids, clipped stuff and merged into one it started having problems in pdf and dwg creation
So I remade the truss differently and everything is now better.
remember that you are using someone else's file and they may not be made as well as yours.

Thanks for the tips Eric,
I have some fairly large files 1.2GB in total. I also have (what I thought) plenty of system resource.
32GB RAM6GB Graphics CardNew i7 Hexcore processor....
I will try running as admin to see if that has an impact.
I am unable to trim bits out of half of the files I'm recieving as they are i.dgn and locked down... I get a pop up often, something about 'Large Level Dictionaries', and have compressed to no avail. I assume that the i.dgn won't allow the removal of unused levels...
anywho.... Back to the grindstone...
Noticing that you mention working with most of the references turned off you might find performance is better if you create a series of sub-master composition files that have smaller groups of references attached, this kind of structure:
To view the relevant files for plant A open plant A sub-master, to see the whole plant open plant master with Nesting Depth set to 1.
As you mentioned compression these notes may be helpful:
What does 'Compress File on Exit' do?
Compress Options in AECOSim Building Designer - Behaviour and Configuration
Compress Options can affect Drawing View performance [in AECOsim Building Designer]
There are several other factors that can affect performance. Some suggestions are made in the following articles:

Drawing Rules, Auto Annotation and performance [essential reading #2]
In ABD SS5 we have added ABD SS5 - BB_DG_ECSCHEMA_CACHE. This speeds up the Element Information dialog. There have been significant improvements to application performance in SS5 and we recommend that you upgrade to it as soon as practicable.
My last project was 3.8 Gb and rendering and plots could take time. some worse than others.
Note that it does not matter if you had 250 Gb of Ram you can only use a small amout 3.5 maybe for Ustn.
That being said I opened up my virtual memory and made sure it was on the HD and not my SSD. that did help some for me.
I also worked on my renderings and BVs and made sure to cut off what I was not needing in reference files.
Re-looking at this and since much of your stuff is cut off I would suggest this.
Create a new file
Copy anything that is not reference files into the new file.
do what you need to do - if crash something here
Then add what you need one at a time and run
Find the culprit
Then add references that are cut off - one at a time.
Sometimes you just have to dissect the issue
