It also integrates with other Bentley products such as MicroStation, AutoCAD, ArcGIS, WaterGEMS, SewerGEMS, and CivilStorm.


In this article, we will explore the new features and improvements that have been introduced in StormCAD V8i (SELECTseries 2), as well as how to use the software effectively for stormwater system design and analysis.


New features and improvements in StormCAD V8i SELECTseries 2




The SELECTseries 2 release of StormCAD V8i introduces numerous new features and improvements that enhance the functionality, usability, and performance of the software. Some of the highlights are:


New predefined flextables




Flextables are tabular reports that display various attributes and results for network elements such as pipes, nodes, catchments, etc. They can be customized by adding, removing, or rearranging columns, applying filters or sorts, changing units or formats, etc.


StormCAD V8i (SELECTseries 2) includes some new predefined flextables that are useful for different purposes:


  • HEC-22 Table A - This is a flextable that follows the format of Table A in the HEC-22 manual (Hydraulic Design of Highway Culverts). It shows information for both pipes and nodes, such as upstream structure, downstream structure, headloss coefficient, velocity head, hydraulic grade line elevation, etc.



  • Network Elements Table - This is a flextable that shows attributes for both pipes and nodes (not catchments) in the same table. It can be used to get a quick overview of the network elements without switching between different tables.



  • Combined Pipe/Node Report - This is a flextable that shows attributes for pipes along with some results from adjacent nodes. It is similar to the HEC-22 Table A flextable but arranged differently.



Formula based user data extensions




User data extensions are custom fields that can be added to any element type in StormCAD. They can be used to store additional information or calculations that are not available in the standard fields.


In previous versions of StormCAD, user data extensions could only contain user-entered values. In StormCAD V8i (SELECTseries 2), user data extensions can also contain formulas that are calculated based on other existing fields.


For example, you can create a user data extension that shows the node depth as the difference between the rim elevation and the invert elevation for a catchbasin. You can also use math functions, if/then/else statements, unit conversions, etc. in your formulas.


Seed file support




A seed file is a file that contains default settings for various aspects of a project such as units, symbology, labels, flextables, etc. It can be used to create new projects with consistent settings or to apply settings to existing projects.


StormCAD V8i (SELECTseries 2) supports seed files for both standalone mode and integrated mode (with MicroStation or AutoCAD). You can create seed files from existing projects or use the default seed files provided by Bentley.


XML reports from flextables




XML (Extensible Markup Language) is a format that allows data to be structured and exchanged between different applications. XML reports can be useful for importing or exporting data from StormCAD to other software or databases.


StormCAD V8i (SELECTseries 2) allows users to generate XML reports from any flextable in the software. You can choose which columns to include in the XML report and save it as an XML file.


Profile enhancements




A profile is a graphical representation of the elevation changes along a pipe network. It shows the pipe invert elevations, node rim elevations, hydraulic grade line elevations, ground elevations, etc.


StormCAD V8i (SELECTseries 2) introduces some enhancements to the profile feature such as:


  • Profile annotation - You can add text annotations to any point on the profile graph by right-clicking on it and choosing "Add Annotation". You can also edit or delete existing annotations by right-clicking on them.



  • Profile zooming - You can zoom in or out on any part of the profile graph by using the mouse wheel or by clicking on the zoom buttons on the toolbar.



  • Profile printing - You can print the profile graph along with its legend by clicking on the print button on the toolbar.



Scenario comparison tool




A scenario is a set of network elements with their properties and results that represent a specific design or condition of a stormwater system. Scenarios can be used to compare different design alternatives or analyze different storm events.


StormCAD V8i (SELECTseries 2) includes a scenario comparison tool that allows users to compare two scenarios side by side in terms of their network elements attributes or results. You can choose which element type (pipes or nodes) and which attribute or result to compare between scenarios.


The scenario comparison tool shows a color-coded map of the network elements indicating whether they have higher or lower values in one scenario compared to another. It also shows a table with numerical values for each element in both scenarios.


Storm data UI improvements




The storm data UI is where users define the storm events and rainfall data for their projects. Storm events are used to specify the intensity-duration-frequency curves or rainfall depths for different return periods. Rainfall data are used to specify the temporal distribution or hyetograph of rainfall for each storm event.


StormCAD V8i (SELECTseries 2) introduces some improvements to the storm data UI such as:


  • Rainfall library - You can access a library of predefined rainfall data sets for various locations around the world by clicking on the "Rainfall Library" button on the toolbar. You can import any rainfall data set from the library into your project or export your own rainfall data set into the library.



```html Selection tool for user notifications




User notifications are messages that appear in the message center window at the bottom of the StormCAD interface. They provide information, warnings, or errors about the network elements or the analysis.


StormCAD V8i (SELECTseries 2) includes a selection tool that allows users to select the network elements that are associated with a user notification by clicking on the message. This can help users to quickly locate and fix any issues or errors in their network.


New calculation options




StormCAD V8i (SELECTseries 2) introduces some new calculation options that give users more control and flexibility over the analysis. These options are:


  • Ignore minor losses at catchbasins - This option allows users to ignore the minor losses due to entrance and exit at catchbasins. This can be useful for modeling systems with large catchbasins where the minor losses are negligible.



  • Use HEC-22 2009 equations for gutter spread - This option allows users to use the updated equations from the HEC-22 2009 manual for calculating gutter spread. These equations account for different curb types and cross slopes.



  • Use HEC-22 2009 equations for inlet capture - This option allows users to use the updated equations from the HEC-22 2009 manual for calculating inlet capture. These equations account for different inlet types and configurations.



  • Use HEC-22 2009 equations for inlet bypass - This option allows users to use the updated equations from the HEC-22 2009 manual for calculating inlet bypass. These equations account for different inlet types and configurations.
