Learn the factors for optimal MEP model performance.
You can use Revit to create models of building services, often in the form of large connected networks. The powerful analytical and parametric modeling capabilities of Revit allow data to flow throughout the connected network while manipulating the model. Improper structure and configuration of large connected networks have a severe impact on model manipulation performance. In comparative testing, models perform significantly better when structured properly.
Create logical systems for your connected networks, rather than leave all elements on the default system. Associating elements into systems streamlines data propagation and facilitates the analytical uses of systems, such as in pressure drop calculations. Testing of customer models with all elements on the default system showed significant improvements when the connected network was restructured as logical systems.
Ensure that the Flow Direction parameter for connectors on families in the connected network is not set to Bidirectional unless the family is placed in-line with connected networks like dampers and valves. The Bidirectional setting makes flow determination more difficult and thus impacts regeneration performance.
