Borders Tab (Surface Style Dialog Box)

Use this tab to specify settings for the border component of a surface object.

Borders display the actual extents of the surface, which can be different from boundaries, which are used to define the surface extents.

Border Display Mode

Specifies how to display the border:

Use Surface Elevation: Displays the border at its actual elevation values.
Flatten Elevations: Flattens or projects the border to the elevation value specified by the Flatten Borders To Elevation property.
Exaggerate Elevation: Scales the border by the factor specified in the Exaggerate Borders By Scale Factor property.

Flatten Borders To Elevation

Specifies the elevation used to flatten the borders; available only when Border Display Mode is set to Flatten Elevations.

Exaggerate Borders By Scale Factor

Specifies the scale factor used to exaggerate the borders; available when Border Display Mode is set to Exaggerate Elevation.

Display Exterior Borders: Specifies whether to display outer borders. The outer border is the outer extents of the surface.
Display Interior Borders: Specifies whether to display all interior borders. This option is useful when you want to build footprints or “holes” in your surface where survey data is not present or applicable, and you do not want to represent elevations for that area.

Use Datum: Specifies whether or not the outer boundary can display a datum. The datum is displayed at the elevation specified in the Datum Elevation property.
Project Grid To Datum: Specifies whether the outer boundary segments are projected to the datum. The projection of outer boundary segments to the datum is only visible when viewing the surface object in 3D.
Datum Elevation: Specifies the datum elevation. The datum is only visible when the border is displayed in 3D.
