Specifies the default distance between labels along the contour. Enter a value or click to graphically select a distance in the drawing area.

Import Options

Note

This property group is displayed when accessing the AddSurfaceFromDemFile and CreateSurfaceGridFromDemFile command settings.

Use these settings to specify the defaults assigned when creating surfaces.

Use Custom Null Elevation

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.

Surface Creation

Note

This property group is displayed when accessing the CreateSurface command settings.

Use these settings to specify the defaults assigned when creating surfaces.

Surface Default Type

Specifies the default surface type that is used when creating a surface. For more information, see Understanding Surfaces.

Surface Name Template
Specifies the name template to use when creating new surfaces. For more information, see Name Template Dialog Box.
Cut Factor
Specifies the cut factor to apply to the volume calculations. As the volume of material generally expands after it is removed, the cut factor is usually set to greater than 1.0, indicating swell or expansion. For example, a 1.2 cut factor would mean that for every 1.0 cubic meter of material removed, 1.2 cubic meters of volume would need to be accounted for transport.
Fill Factor
Specifies the fill factor to apply to the volume calculations. As the material generally compacts when used as fill, the fill factor is usually set to greater than 1.0, to indicate compaction or shrinkage of the material when it is used as fill. For example, a 1.2 fill factor would mean that for every 1.0 cubic meter of material required for the fill site, 1.2 cubic meters of that material would need to be transported. For example, for a material that compacts to 93% of its original value when used as fill, enter 1.075 (which is derived by dividing 1.0 by .93) as the fill factor to compensate for the extra material that must be added.
Grid Surface X-Spacing

Specifies the default value for a grid surface's X spacing.

Grid Surface Y-Spacing

Specifies the default value for a grid surface's Y spacing.

Specifies the default volume surface type that is used when creating a volume surface. For more information, see Creating a TIN Volume Surface and Creating a Grid Volume Surface.

Volume Surface Name Template
Specifies the name template to use when creating new volume surfaces. For more information, see Name Template Dialog Box.
Cut Factor
Specifies the cut factor to apply to the volume calculations. As the volume of material generally expands after it is removed, the cut factor is usually set to greater than 1.0, indicating swell or expansion. For example, a 1.2 cut factor would mean that for every 1.0 cubic meter of material removed, 1.2 cubic meters of volume would need to be accounted for transport.
Fill Factor
Specifies the fill factor to apply to the volume calculations. As the material generally compacts when used as fill, the fill factor is usually set to greater than 1.0, to indicate compaction or shrinkage of the material when it is used as fill. For example, a 1.2 fill factor would mean that for every 1.0 cubic meter of material required for the fill site, 1.2 cubic meters of that material would need to be transported. For example, for a material that compacts to 93% of its original value when used as fill, enter 1.075 (which is derived by dividing 1.0 by .93) as the fill factor to compensate for the extra material that must be added.
Grid Surface X-Spacing

Specifies the default value for a grid surface's X spacing.

Grid Surface Y-Spacing

Specifies the default value for a grid surface's Y spacing.

Grid Surface Orientation

Specifies the default orientation for a grid. Enter a value or click to graphically select an orientation in the drawing area.

Build Options

Note

This property group is displayed (in different forms) when accessing the CreateSurface, CreateSurfaceGridFromDemFile, and VolumesDashboard command settings.

Use these settings to specify the build options assigned when creating surfaces.

Note

Use these settings when creating a surface, but not when importing a surface from LandXML, DEM, or TIN.

Copy Deleted Dependent Objects

Specifies whether a drawing object is copied to the surface definition item if the object is deleted.

Exclude Elevations Less Than

Specifies whether an elevation less than a certain value should be excluded when the surface is built.

Elevation <

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.

Exclude Elevations Greater Than

Specifies whether an elevation greater than a certain value should be excluded when the surface is built.

Elevation >

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.

Use Maximum Angle

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.

  • If the Maximum Angle Between Adjacent TIN Lines setting is set to 130 degrees, the highlighted triangles in the following illustration would be removed.

  • If the Maximum Angle Between Adjacent TIN Lines setting is set to 140 degrees, the highlighted triangles in the following illustration would be removed.

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.

Maximum Angle Between Adjacent TIN Lines
Specifies the maximum angle to use for the Use Maximum Angle option (CreateSurface and VolumesDashboard command settings only). A triangle is removed from the TIN if the angle which faces to the border edge exceeds the maximum angle specified.
NoteIf both Use Maximum Triangle Side Length and Use Maximum Angle are set to Yes, then the Use Maximum Angle operations are completed before the Use Maximum Triangle Side Length operations.
Use Maximum Triangle Side Length

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).

Maximum Triangle Length

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).

Convert Proximity Breaklines to Standard

Specifies whether proximity breaklines are converted to standard breaklines when the surface is built (CreateSurface and VolumesDashboard command settings only).

Allow Crossing Breaklines

Specifies whether breaklines can cross each other (CreateSurface and VolumesDashboard command settings only).

Elevation To Use

Specifies the elevation to use for the crossing breaklines (CreateSurface and VolumesDashboard command settings only):

  • Use First Breakline Elevation At Intersection: Uses the first breakline elevation to determine the elevation at the intersection.
  • Use Last Breakline Elevation At Intersection: Uses the last breakline elevation to determine the elevation at the intersection.
  • Use Average Elevation At Intersection: Uses the average of the first and last breakline to determine the elevation at the intersection.

For more information on these settings, see the Build properties in Definition Tab (Surface Properties Dialog Box).
