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.
-

Surface Creation
Note: This property group is displayed (in different forms) when accessing the
CreateSurface,

-
Surface Default Type

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

If you choose to save the reference surface geometry in the drawing, the drawing that contains the reference will become larger, but will open more quickly unless the source surface has changed. For more information, see

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.

-
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.

Use Maximum Angle are set to Yes, then the
Use Maximum Angle operations are completed before the
Use Maximum Triangle Side Length operations.
-

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
