Bentley Ships All-New StormCAD, No. 1 Hydraulic Modeling Solution for Stormwater Networks

EXTON, Pa.—(BUSINESS WIRE)—November 14, 2007— Bentley Systems, Incorporated has begun shipping StormCAD V8 XM Edition, an easy-to-use storm sewer network design and modeling solution that is the first to offer multiplatform interoperability. StormCAD was identified as the No. 1 hydraulic modeling solution for stormwater networks in a recent national survey.

The new StormCAD release provides multiplatform interoperability across MicroStation, AutoCAD, and stand-alone environments. This means users can now build, edit, run, and analyze StormCAD models directly inside MicroStation, the platform used by 47 of the 50 U.S. state departments of transportation and the U.S. Federal Highway Administration. In addition, they can use StormCAD for AutoCAD, with support for the recently released AutoCAD 2008, or StormCAD's easy-to-use stand-alone environment.

Said Todd Nochomson, CAD systems manager at Miller Legg, which participated in the early adopter program for StormCAD V8 XM Edition, "We recognize that the entire industry is moving towards interoperable analysis and civil design models, and the new StormCAD is a perfect implementation of this trend. A great example is the new support for the industry-standard LandXML format, which allows us to transparently share our hydraulic and civil design models regardless of the vendor we choose for each discipline."

Added Kelly Lee, project engineer at Miller Legg, "Bentley is keeping up with market and technology trends with the new StormCAD. The new stand-alone interface not only looks great, but it's also very easy to learn and use. From navigating the model with the new dynamic zooming to the flexible new profiling features, the new tools in StormCAD are already making us more productive in our everyday storm sewer design projects."

StormCAD V8 XM Edition shares the innovative water solutions technologies that users of Bentley's CivilStorm, SewerGEMS, WaterCAD, and WaterGEMS already enjoy, and that resulted in WaterGEMS' People's Choice Award win at last year's AWWA Annual Conference and Exposition. For example, its all-new stand-alone interface comes with dozens of new productivity tools designed to simplify workflows and make storm sewer network design easier than ever.

Additional new features of StormCAD V8 XM, highlighted by interoperability and ease of use, include:

-- Active topology alternatives - Users can now set up different scenarios to examine multiple proposed system expansion strategies.

-- LandXML import/export - The new StormCAD facilitates sharing storm sewer pipe network information with other LandXML-compatible civil design packages.

-- Support for prismatic open channels - New modeling elements include trapezoidal channels, rectangular channels, and irregular (user-defined) channels.

-- Terrain elevation extraction - Automatically assign node elevations based on elevation data from DXF files, Shapefiles, or LandXML files.

-- Time of concentration calculator - Support for several time of concentration methods including SCS Lag, TR-55, Kirpich, and Eagleson.

-- Scaled catchments, gutters, and diversions - These elements can now be drawn directly and to scale for a better graphical representation of the system.

-- Inlet capacity curves - Model any type of inlet by entering a "gutter depth vs. flow captured" curve or "flow to inlet vs. flow captured" curve.

-- User-defined flow-headloss curves - Model complex elements such as vortex regulators by entering a user-defined flow-headloss curve.

-- Contours - Quickly create a contour plot of model input or results and export these directly to MicroStation, AutoCAD, or DXF format.

-- Customization using WaterObjects.NET - Customize and extend StormCAD using the WaterObjects.NET application programming interface.

StormCAD V8 XM Edition is immediately available to all Bentley SELECT subscribers. For more information on StormCAD V8 XM Edition, please visit

About the Water Resources Modeling Software Survey

This national survey was commissioned by Bentley and conducted across the readership of CE News' Civil Connection, a leading civil engineering newsletter published by ZweigWhite. The survey asked licensed civil engineering professionals employed by leading consulting engineering, survey, and construction firms and key public works departments, utilities, and municipalities about their software preferences in seven categories of water resources modeling software. Bentley solutions claimed the No. 1 position - receiving up to more than three times the top responses of the closest competing products - in the following five categories: water distribution, transient analysis, wastewater conveyance, stormwater networks, and general hydraulics.
