Models or DGNS which is better?

So we are still in the early days of adopting ORD in my organization. I was wondering if anyone has seen any performance difference between using multiple models in a single dgn VS using multiple DGNs?

our previous method was to create multiple DGNs and reference them as parts of the drawings. what I'm wondering is if theres a benefit to say placing all the parts of a design model in the same dgn and just using model spaces to separate them.

For Example a Detour.dgn would have the following as models:

-Detour Alignment

-Detour Corridor

-Detour Terrain

-Detour Earthwork

I was thinking the main benefit would just be reducing the number of separate files we generate but was also hoping that maybe it comes with fewer crashes and better functionality??

  • I like to use separate DGN's for each corridor. Separate DGN's for each superelevation, and for Geometry.  There could be some combining for things like small corridors or simple geometry but seems best to separate them.  ORD is creating and managing models and 3D models so I do not like to get to much going on in one DGN.  Additionally multiple models allows for multiple users to participate in the Design.  Then there is always the corrupt file from time to time.  If my data is in separate DGN then each container has safe data.
