I'm involved in a project that includes a site model + 80 houses, made up of about 20 different types.
What file set up do you recommend?
All houses have the same Storey setup so my first instinct is to put the site model and all of the house type models into one Project File. And then all sheets into a separate file, workgroup referenced to the main Project File (to keep the model file nimble).
I was trying to track down the very useful 'file setup efficiency' testing that Martyn Horne and team presented at the BIM Design Day in London back in October but haven't put my finger on it yet.
