AutoCAD MEP 2015 streamlines the design workflow through several automated systems:

: Designers work with "systems" rather than simple lines. For instance, drawing a duct automatically adds necessary fittings based on predefined routing preferences.

: Simplified duct routing with automatic placement of elbows, tees, and reducers.

: A built-in Display Manager automatically handles geometry, layers, and colors, removing the need for manual layer manipulation.
