This value is the number of points that the simplify surface command removed within the selected boundary. Percentage Of Points To Remove: Selected, 50%Īt the bottom of the wizard, notice the Total Points Removed value.On the Reduction Options page, specify the following parameters:.This is the current number of points in the selected region. In the Simplify Surface wizard, notice the value for Total Points Selected In Region. In the drawing, click the orange corridor boundary.On the Region Options page, specify the following parameters:.In the Simplify Surface wizard, on the Simplify Methods page, select the Point Removal option.Click Surface tab > Modify panel > Edit Surface drop-down > Simplify Surface Find.Click Modify tab > Ground Data panel Surface Find.

These polylines will enable you to observe the results of the Simplify Surface command. These layers contains polylines that represent the original major and minor contours. Next to the C-TOPO-CONT-MAJR-ORIG and C-TOPO-CONT-MINR-ORIG layers, click. Click Home tab > Layers panel > Layer drop-down.This exercise uses Surface-2.dwg with the modifications you made in the previous exercise. Points that are used to define surface borders and breaklines are not removed with the Simplify Surface command. You cannot specify which points to remove. More points are removed from areas in which the concentration of points is very dense than from areas that contain fewer points. This method randomly selects points from the surface, and removes them based on the point density at different areas of the surface. In this exercise, you will use the Point Removal method of simplifying a surface. The original surface points are still contained in the referenced point file, but are not used in the surface triangulation. When the simplify surface command is complete, new points and TIN edges are calculated based on specified parameters. In this exercise, you will reduce the number of points that are used to define a surface.Ī surface can be simplified by removing either TIN edges or points.
