My way of thinking of this would be to do it with versioning. Ie for each city square you have a base mesh possibly as emdl to be referenced in. e.g. square_001_base
In your first project you will pull those in and place via reference so their edges are correct. Once you have that you can then create different versions of the base squares wether its by naming convention i.e. square_001_x, square_001_y or something like Git / mercurial Then in order to change which squares you pull into the project you can just edit the scntoc file for file bases versioning , or the files will be replaced by the correct ones if you use some form of source control. You could also possibly do it via Level of detail proxies (they will be about the same amount of detail but that’s not really an issue for this) I am sure there is also likely a scripting way to do this easily as well.

Our projects require us to make different versions of these squares for planning purposes. So for any given square, we may have 4 or 5 different versions. The more projects we do, the more complicated it gets for us to keep track of what belongs (and what fits) together. When we need to quickly prepare a file that contains "City model with Project X + Project Y", we have two main problems: a) For squares with multiple versions we need to figure out which of these versions are part of Project X and which are Project Y. b) We need to figure out how squares may be combined. Let's say that the square F003_C belongs to Project X, but square G003 is not part of Project X. We now can't be sure which version(s) of G003 properly match(es) F003_C at the seam. I'm unsure how common a problem this is and whether I explained it properly. Does anybody have any pointers as to what may be a good way to tackle this? Maybe some kind of specialized software?
