Use this dialog box to view and change surface-related settings.
This topic documents settings in all surface-related Edit Settings dialog boxes (drawing-level, feature-level, and command-level).
For general information about drawing, feature, and command settings and their interaction, see About Autodesk Civil 3D Settings.
For information about drawing-level ambient settings, see Ambient Settings Tab (Drawing Settings Dialog Box).

Use this setting to specify the default name format for new surfaces. Click in the Value column, and click to make changes in the Name Template dialog box.
Use these settings to specify the defaults assigned to surface labels.
Specifies whether or not the contour label lines are displayed.
Specifies the default major contour label style. Click in the Value column, and click to select a style in the Surface Contour Label Style Major dialog box.
Specifies the default minor contour label style. Click in the Value column, and click to select a style in the Surface Contour Label Style Minor dialog box.
Specifies the default user-defined contour label style. Click in the Value column, and click to select a style in the Surface Contour Label Style User-defined dialog box.
Specifies Automatic as the default setting for the Rebuild Surface command.
Specifies the default Surface Level of Detail for new surfaces created in a drawing. If set to Yes, the default is Reduced.
When Yes is selected, the appropriate style display component is activated when using surface editing commands. For example, swapping surface triangle edges will automatically display triangles in the surface style.
Use this setting to specify the defaults assigned to surface labels.
Specifies the default distance between labels along the contour. Enter a value or click to graphically select a distance in the drawing area.
Use these settings to specify the defaults assigned when creating surfaces.
Specifies whether a custom null elevation is used when importing a surface from a DEM file.
Specifies the default custom null elevation used when importing a surface from a DEM file.
Specifies the default surface type that is used when creating a surface. For more information, see About Creating Surfaces.
Specifies the default value for a grid surface's X spacing.
Specifies the default value for a grid surface's Y spacing.
Specifies the default orientation for a grid. Enter a value or click to graphically select an orientation in the drawing area.
Use these settings to specify the defaults assigned when creating volume surfaces from the Volumes Dashboard.
Specifies the default volume surface type that is used when creating a volume surface. For more information, About Creating Surfaces.
Specifies the default value for a grid surface's X spacing.
Specifies the default value for a grid surface's Y spacing.
Specifies the default orientation for a grid. Enter a value or click to graphically select an orientation in the drawing area.
Use these settings to specify the build options assigned when creating surfaces.
Specifies whether a drawing object is copied to the surface definition item if the object is deleted.
Specifies whether an elevation less than a certain value should be excluded when the surface is built.
Specifies the elevations to exclude when the Exclude Elevations Less Than property is set to Yes. Enter a value or click to select an elevation in the drawing area.
Specifies whether an elevation greater than a certain value should be excluded when the surface is built.
Specifies the elevations to exclude when the Exclude Elevations Greater Than property is set to Yes. Enter a value or click to select an elevation in the drawing area.
Specifies whether the triangles on the exterior border of the TIN will be assessed to see if they exceed the Maximum Angle Between Adjacent TIN Lines (CreateSurface and VolumesDashboard command settings only). If Use Maximum Angle is set to Yes, triangles on the exterior border of the TIN are assessed. A triangle is removed from the TIN if the angle which faces to the border edge exceeds the maximum angle specified.
The following illustrations show examples of the effect of the Use Maximum Angle setting.
This process is iterative so that when a triangle is removed, exposing one or two new border edges, the new border triangles are tested and removed according to the same criterion. This operation assesses triangles that border exterior boundaries. Triangles on interior boundaries are not affected by this operation.
Specifies whether the surface triangles that exceed the length specified by the Maximum Triangle Length property are removed from the boundary of the surface (CreateSurface and VolumesDashboard command settings only).
Specifies the triangle length to use when the Use Maximum Triangle Length property is set to Yes. Enter a value or click to select a length in the drawing area (CreateSurface and VolumesDashboard command settings only).
Specifies whether proximity breaklines are converted to standard breaklines when the surface is built (CreateSurface and VolumesDashboard command settings only).
Specifies whether breaklines can cross each other (CreateSurface and VolumesDashboard command settings only).
Specifies the elevation to use for the crossing breaklines (CreateSurface and VolumesDashboard command settings only):
For more information on these settings, see the Build properties in Definition Tab (Surface Properties Dialog Box).
Use these settings to specify default water drop path options for surfaces.
Specifies the default layer on which to draw the water drop path. Click in the Value column, and click to select a type of path in the Path Layer dialog box.
Specifies the default type of AutoCAD object to use for the water drop path. Either 2D Polyline or 3D Polyline.
Use these settings to specify default water drop marker options for surfaces.
Specifies whether to draw a marker at the start point of the water drop path.
Specifies the default start point marker style. Click in the Value column, and click to select a style in the Start Point Marker Style dialog box.
Use these settings to specify default options for simplifying surfaces.
Specifies the default method by which surfaces will be simplified:
Specifies the default method by which surfaces will be simplified:
Specifies whether simplify the image by removing a percent of surface points.
Specifies the percent of surface points to remove.
Specifies whether you will set a default maximum change in elevation.
Specifies the maximum allowed difference between the elevation of the original surface and the elevation of the simplified surface.
