After a toposurface has been simplified, verify the contours and geometry. When a toposurface is simplified, the accuracy and geometry of the contours may be affected depending on the specific conditions of the toposurface. When a toposurface is created using a large number of points, you can simplify the surface to improve system performance. Create a Toposurface with a Points FileĮxport a points file from a civil engineering application, and import it to create a toposurface in the Revit model.Įach point in a toposurface creates triangulated geometry, which adds to the computational overhead.Create a Toposurface by Importing Contour DataĪutomatically generate a toposurface based on 3D contour data imported from DWG, DXF, or DGN files.Watch these videos to learn how to create and work with toposurfaces, subregions, and graded regions.Ĭreate a toposurface by placing points in the drawing area. Videos: Create Toposurfaces and Regions.You can create toposurfaces in 3D views or site plans. The Toposurface tool defines a topographical surface (a toposurface) using points or imported data.
