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 Level: Displays the border at its actual level values.
Flatten Levels: Flattens or projects the border to the level value specified by the Flatten Borders To Level property.
Exaggerate Level: Scales the border by the factor specified in the Exaggerate Borders By Scale Factor property.

Flatten Borders To Level

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

Exaggerate Borders By Scale Factor

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

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 levels for that area.

Use Datum: Specifies whether or not the outer boundary can display a datum. The datum is displayed at the level specified in the Datum Level 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 Level: Specifies the datum level. The datum is only visible when the border is displayed in 3D.
