Following various advice on BIM best practice I've been setting up a project involving two buildings with a separate file for the site model and separate files for each of the two building models. All origins are synced across files (I'm using rotated view to work on the models) and I've managed to use Layer Import mode when referencing by having unique names for Design Layers + Story Names and Prefixes across the project.
But workgroup referencing is bringing with it a whole host of trouble-shooting problems (and another [long] step in the file-save process). I find it very buggy. Which begs the question: why am I putting my building models (and sheets) in separate files?
I would rather work in a single file for a host of reasons (including being easier for my colleagues to manage). Vectorworks can easily handle a project this size (two houses with 4 levels). And in terms of collaboration with other consultants, it doesn't matter that I have separate files or not does it?
Convince me. @shorter?
