I have an assembly model that is runnig terribly slow. it has taken over 20mins to simply mirror a piece of RSA from the comtent centre & (as i type) has taken 30 mins to change from one levle of sdetail to another.
I've tried a few things to speed it up to no avail. These include;
all parts in the assembly are stored on a local hard drive
no adaptive parts in the model or sub assemblies
i've opened other models & manipulated other larger assemblies on this & other projects to determine if this issue is limited to this particular assembly & it appear so.
i've done so many re-starts, rebuilt the assembly numerous times, cleaned up my hard drives and so on.
yet this particular assembly refuses to work . its only 450 parts or thereabouts & has no weird surfaces, it mostly steels tube & angle from the content centre.
Any advice would be appreciated.

Can you try to delete all custom Views, Positions, Level of Details.
You can also try to move half of the components in another place, so Inventor opens the Assembly without them. So you can isolate if there is a problematic one. You can also remove all the components and open the top Assembly without anything, to see if the top assembly is problematic.
Unfortunately it was the failure of those 2 suggestions to improve things that prompted my original post.
Deleting the design views & LOD's was itself problematic, taking an hour or so to delete a particular LOD.
I had thought it might be a problem to do with having a few hundred parts not yet demoted into logical sub assemblies. However this hasn't been a problem before & the parts were simple steel tubes & angle.
I also tried saving to a new file name, deleting major components, checking individual components for obvious issues, & deleting large numbers of parts out of the top level assembly , using the rebuild button - all to no avail.
Just what does the rebuild tool do? Does it make any difference at all ?
There's a lack of diagnostic tools in Inventor which makes these sort of issues very frustrating. Everything is great until you get a problem & using "the force" isn't a great approach.
The solution I've settled on is to remodel the whole thing. Not too time consuming (about a day) but it will be a problem later because I've already created detailed drawings of the broken top level assembly which will also need to be re-created based on the new assembly (and that will take much longer to do).
That said I'm not giving up on my original model just yet, so if you've got any more ideas please shoot them my way.
Basically the first point it to isolate whether the problem comes from :
Opening the assembly without any component is one way to isolate whether it's number 1 or 2.
Deleting all Pos Reps, Design and LODs is the way to isolate number 3.
Of course, if the assembly is very slow, then this might take time.
You can try to open the assembly using the options Design View "Nothing Visible" and LOD "All Parts suppressed"
