Updated support for MicroStation: You can run StormCAD from within the latest releases of MicroStation V8i (SELECTseries 3). A MicroStation license is required – if you don't have a MicroStation license, you can choose to run StormCAD in stand-alone mode.

Updated support for AutoCAD: You can run StormCAD from within AutoCAD 2015 and 2014. An AutoCAD license is required – if you don't have an AutoCAD license, you can choose to run StormCAD in stand-alone mode.

Direct import of MX Drainage files: The import of MX Drainage files in StormCAD has been improved, reducing the steps necessary to leverage MX Drainage data.

Bentley Map Mobile i-model publishing: This tool publishes a StormCAD model, including results, for use in Bentley Map Mobile, a free app that works on Android, iPad, and iPad mini tablets..


Elevation data assignment: StormCAD can automatically assign elevation data to node elements, using digital terrain models. The node elevation can be updated automatically when the element is moved.

Downstream trace: StormCAD enables the convenient trace and display of the surface water flow direction across any terrain.

Redesigned conduit catalog: Conduits with the same section shape and materials are now grouped together in the conduit catalog, making it easier to view and edit them.


Headwall and endwall elements: StormCAD now supports culvert headwalls and endwalls, which can connect to open channels or closed conduits.

Inlet-only hydraulic calculations: Users can now place inlets, check gutter and inlet carryover flows, and adjust the inlet positions as necessary, before designing the pipe network.

Improvements to automated design: The automated design calculations for storm sewers include a number of enhancements, such as: pipe wall thickness can be included when computing cover; drop structures can be used to minimize cover (previously drop structures only prevented a pipe from exceeding the maximum allowable slope); and a minimum drop depth can be specified for drop structures.


New loss methods: StormCAD now allows users to compute infiltration losses using ‘initial loss and constant fraction’ or ‘initial loss and constant rate’ methods.

New time of concentration methods: StormCAD now supports the following additional time of concentration calculations: Kinematic Wave equation, Friend’s equation and Bransby-Williams equation.
