Key New features In SewerGEMS V8i: Engine updates The new SewerGEMS V8i now installs two individual programs: * SewerGEMS (dynamic wave solver) for which: o the SWMM solver has been updated to version 5.0.14 o the Dynamic Wave Solver has been improved (for low flow where the user can now specify virtual depth at which virtual flow calculations occur) * the new SewerGEMS Sanitary provides the same features as SewerCAD with the added ability to work within the ArcGIS platform. This means that SewerGEMS Sanitary allows engineers to use steady-state analysis with various standard peaking factors and extended-period simulations, as well as the powerful and easy-to-use Automatic Design features. Updated GIS and CAD interoperability Support for ArcGIS v9.3: Run SewerGEMS in ArcGIS 9.3 (ArcGIS license required - if you don't have an ArcGIS license, you can choose to run SewerGEMS in its stand-alone mode). Support for MicroStation V8i: Run SewerGEMS in MicroStation V8i (MicroStation license required - if you don't have an MicroStation license, you can choose to run SewerGEMS in its stand-alone mode). Support for ProjectWise V8i: Manage SewerGEMS files using the ProjectWise project team collaboration system. Support for SELECT Server V8i Support for AutoCAD 2009: Run SewerGEMS in AutoCAD 2009 (AutoCAD license required - if you don't have an AutoCAD license, you can choose to run SewerGEMS in its stand-alone mode). Improved model building Easier model maintenance with the GIS-ID property: The new GIS-ID property can be used for maintaining associations between records in your source file and elements in your model. ModelBuilder improvements (to create new models or update existing ones from different data sources): * Oracle Spatial support for ModelBuilder. * It is possible to import a subset of data using where queries. This allows users to filter the data to import only the information they need, without having to change the data from its original format. * Automatic creation of selection sets containing model elements that were either added or updated. * Update the currently selected scenario or create a new child scenario during the data import process. Using a child scenario allows you to see the changes that were made by ModelBuilder during the last model-build operation. Easier model management Easily and quickly create a prototype for a new element by right-clicking any element in the drawing view and selecting the ‘Create Prototype’ menu option. New Merge Nodes in Close Proximity tool to automatically merge duplicate nodes and reconnect conduits. It is now possible to import/export SewerGEMS' sub-models. Interpretation of results You can now export the results to Google Earth when using the MicroStation and ArcGIS platforms. Enhanced display options Highlighted link elements (in the drawing view) can now be differentiated both by color and by symbol size. Accelerated redraw option provides compatibility with a wider range of video cards.
