From these areas, the drain targets and watersheds are determined. Objects derived from AeccWatershedRegion have other common features. Click to generate the watershed analysis. Hydraflow Hydrographs Extension. In Autodesk Civil 3D, the build process for surfaces is incremental. Depending on the nature of the drain target, each watershed region is a different type derived from AeccWatershedRegion. This splits the surface into separate regions, each with its own drain target or targets. 3D Watershed tutorial. Civil 3D civil engineering design software supports BIM with integrated features to improve drafting, design, and construction documentation. A region can also drain into many other regions through a series of line segments. A watershed analysis predicts how water will flow over and off a surface. Ensure that Standard is selected in the Legend list. © Copyright 2021 Autodesk Inc. All rights reserved. Lecture 6.2. Configuring and creating a watershed analysis.
