Simplify a Toposurface

Each point in a toposurface creates triangulated geometry, which adds to the computational overhead. When a toposurface is created using a large number of points, you can simplify the surface to improve system performance. When a toposurface is simplified, the accuracy and geometry of the contours may be affected depending on the specific conditions of the toposurface. After a toposurface has been simplified, verify the contours and geometry. Add points for accuracy if needed.

1. Click Modify | Topography tabSurface panel (Edit Surface).
2. Click Edit Surface tabTools panel (Simplify Surface).
3. Open the site plan view and select the toposurface.
4. Enter a value for surface accuracy, and click OK.
5. Click (Finish Surface).
