Hello RevitCity! I have been reading advice on this site for 2 months now and it has proven very useful. I have only made a couple of posts though, and thought I should formally introduce myself before asking a much broader question. I am working on a project for an apartment complex and we will have 7 building types that are each very different but will use arrangements of identical exterior walls, interior units, and various assemblies. All of these are currently grouped. Now we have fairly fancy computers at our office, I'm using a dual-core 2.66 mhz w/ 3 GB of ram (3 GB switch not enabled (yet)) on 32-bit XP with some graphics card (but openGL is turned off due to lots of visual artifacts and crashes) Despite this, we have huge speed problems with our Revit work and we don't expect to be able to build a file with 7 apartment buildings in it. We also had advice on groups (from our distributor) that said that linking groups between files was a bad idea, because basic issues like wall cleanups will take forever. (We still need to tweak our groups so that wall cleanups require much less effort and hair-pulling). Anyway, I'm rambling. The big question is: What happens if we put each building type on a different workset in the same file? If you turn workset visibility off, will manipulating objects in the file be faster and easier? I know the file size will be large, there's nothing we can do about that, but if it could at least be manageable, then I think we'd be ok. One apartment model that is already completed sits at about 20 MB. I just dont' know if increased performance is a byproduct of managing workset visibility or if it is simply a tool for organization. If anybody would like to chime in on this, feel free to! Oh man, I'm sorry about the length.  Thanks, Kevin

Are all your building modeled in the same file? If so I would suggest modeling them individually then linking them into a master site plan. you can then turn the links on and off. As far as worksets are concerned you will get better performance if in your worksets dialogue you changed certain worksets from Opened/Yes to Opened/No. Have you read the Technical Note from Autodesk on Model Optimization?

If they are truly separate buildings then you should always model them separately and link to a site file. Its always easier and faster to work with separate files and link rather than modelling in a single file. And its a lot easier to document the project this way. I did a project once where I had: An apartment type linked into a typical level type, linked into a typical building type, linked into a site masterplan. We originally started using groups and found them to unreliable in terms of basically have to delete them and recopy them around each time. HTH.
