Use this dialog box to add boundaries to the surface definition of the selected surface.
- Name
-
Specifies the name of the boundary to be created. If you do not specify a name, the following default naming convention is used: “Boundary<#>.” For example, if you do not enter a name, the first boundary is named “Boundary1,” the second boundary is named “Boundary2,” and so on.
- Type
-
Specifies the type of boundary to add.
- Outer: Creates an outer boundary for the surface.
Note: Although you can define more than one outer boundary for a surface, only the last one created is used by the surface.- Show: Creates a show boundary. Show boundaries are used to display an area inside a hide boundary.
- Hide: Creates a hide boundary. For a hide boundary, a surface may be selected as the boundary for another surface when the option to use non-destructive breaklines is also selected.
- Data Clip: Creates a surface boundary limited by a polygon object from the drawing, such as 2D and 3D polylines, feature lines, survey figures, parcels, and circles. Any data added to a surface following a data clip boundary is clipped to that boundary.
- Non-Destructive Breakline
-
Specifies whether or not to create boundaries with non-destructive breaklines. This clips the triangle edges exactly where they cross the boundary. This option is unavailable for grid surfaces or when Data Clip is selected as a boundary type.
- Mid-Ordinate Distance
-
Specifies the mid-ordinate distance for the boundaries breaklines, which is used to tessellate the polyline arcs from which the boundary is being created. Click
to digitize the mid-ordinate distance in the drawing area.
