Using the surface analysis tools in Civil 3D, you can gather topographic information about the site with which you are working. Autodesk Civil 3D uses the surface TIN lines to calculate the areas that water would flow along the surface. The X, Y, and Z coordinates of this point are held in a variant array in the AeccWatershedBoundaryPoint.BoundaryDrainPoint property. If a depression on the surface has a minimum average depth smaller than the value of the AeccSurfaceAnalysisWatershed.MergeDepression property, then the depression does not become its own region and is combined with the region it drains into. Posts. Make a new site for each parcel type. Mark Schnesk discusses how to display and employ your Civil 3D surface as a Watershed Analysis style. When I produced the watershed analysis, the little selector arrows for selecting "Merge depressions into single drain targets when Minimum Average Depth is less than:" does not allow selection in 2015 release. A region of the surface may drain through a point into many different regions. Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.

The analysis is created by calling the AeccSurfaceAnalysisWatershed.CalculateWatersheds method. From these areas, the drain targets and watersheds are determined. Configuring and creating a water drop analysis. The Autodesk MicroDrainage Utility provides the ability for Autodesk Civil 3D Pipe Networks to be renamed and exported to MDX/SWS/FWS format for analysis within the MicroDrainage System 1 drainage design module and then imported to update the pipe network in Autodesk Civil 3D to create a 3D model of drainage network as well as product plans, sections and pipe and structure schedules. From these areas, the drain targets and watersheds are determined. The Prospector list view displays a tabular list of the surface watersheds with their IDs, description, type, and the ID of the watershed that they drain into. To translate this article, select a language. A watershed analysis predicts how water will flow over and off a surface. Whenever data is added or corrected, the surface is updated. Optionally, pan or zoom to an individual watershed. They also have a AeccWatershedRegion.Boundary property, which contains a 2-dimensional array containing the points of a closed polygon enclosing the region. Each surface has a definition list. If Autodesk Civil 3D determines that water from one surface triangle could flow into more than one watershed, then it splits the TIN triangle to make two triangles.
