Once a connection is established, it can be saved for later use, and multiple connections can be created and synchronized simultaneously. A topographic representation of the network can be created by using node coordinates and assigning to and from nodes to pipes. Allows exchange of most any model data with a wide variety of applications (ODBC). Convert existing lines, polylines, and blocks in DXF/DWG format into pipes and other network elements. Create connections to import and export model data in ESRI shapefile format. Network Building Using External Data Method Description Advantages Disadvantages Database Connection Shapefile Connection Polyline to Pipe Conversion Create connections to import and export model data using common database and spreadsheet formats. This lesson covers the three main methods of building your network using external data, summarized in the following table.

You can also copy tables, reports, and graphs and paste them into other Windows applications, or save plan and profile views in.dxf format for use when creating construction documents in CAD. Bentley WaterCAD V8i also uses database and shapefile connections to export data from the model for use externally. Finally, Bentley WaterCAD V8i will automatically import networks created in EPANet, KYPIPE, and previous versions of Cybernet/WaterGEMS. This allows the pumps to be imported into the model, and assigned a previously created (or imported) pump definition, according to the name of the pump definition. Shapefile and database connections can, however, store the name of the pump definition, as well as other single-field pump data such as elevation, label, and relative speed. These data types can only be imported in this way since this data occupies more than a single database field, shapefile and database connections cannot be used to bring pump definitions or patterns into the model. Patterns and pump definitions can also be imported, from specially formatted text files. Or, you can display a.dxf file as a background drawing for use in laying out a scaled network (WaterCAD V8i version only). If you have existing drawings of your network in a.dxf format (.DWG format in the AutoCAD version), you can have Bentley WaterCAD V8i convert your lines and/or blocks into distribution system elements, setting up preferences for handling situations such as T-intersections and line endpoints, and creating tolerances to allow for drawing imperfections. GIS information can be brought in through connections to ESRI shapefiles. You can set up one or more database connections to bring in information stored in many standard database and spreadsheet formats. There are multiple ways of importing data from outside sources into Bentley WaterCAD V8i. For instance, you can exchange data with databases or a GIS system, or you can convert existing CAD linework to a pipe network. 1 Working with Data from External Sources Bentley WaterCAD V8i supports several methods of exchanging data with external applications, preventing duplication of effort and allowing you to save time by reusing data already present in other locations.
