HydroCAD® Stormwater Modeling - Since 1986
|
CAD Watershed ImportHydroCAD provides direct import of watershed data from AutoCAD® and BricsCAD® without any additional software. This capability works with all AutoCAD and AutoCAD-based products such as Civil-3D®. Please note that AutoCAD-LT and BricsCAD-Lite are not supported. Supported versions
Try it YourselfIf you are already using HydroCAD (including the HydroCAD Sampler) you can use the sample project and drawing that are pre-installed with HydroCAD. Please review the CAD setup notes and then refer to the "CAD Import Tutorial" in the Help menu. How it WorksThe following "CAD Import Overview" is copied from the HydroCAD help system. CAD Import Overview HydroCAD provides the ability to import subarea data directly from a CAD drawing file, as configured on the Settings|Watershed screen. The data is automatically extracted from the following drawing layers:
Layers are named and created on the Settings|Watershed screen, which also provides additional options such as layer sets, commonly used for mapping of multiple scenarios such as pre/post conditions. After the watershed settings have been configured and the watershed information has been drawn on the designated layers, the actual import process is controlled by the Watershed Import Control button on the right-hand toolbar:
HydroCAD analyzes the input layers and populates the subarea layer with regions for each of the intersections of all the input layers. Each region is then imported into the HydroCAD project as a separate subarea line in the appropriate subcatchment. Subcatchments are automatically created and positioned according to the selections on the Settings|Watershed screen.
When the hot track option is selected, drawing areas are automatically highlighted as individual nodes are selected on the routing diagram. For a step-by-step example please see the CAD Import Tutorial in the help system. Error MessagesIf a problem occurs during the import process, a detailed error message will appear as discussed here.
