Use this dialog box to add contour data to the surface definition of the selected surface. Weeding and supplementing factors are used to add or remove vertices along a contour.
- Description
-
Specifies the description of the contour data operation. If no description is specified, a default naming convention is used: “Contour Data<#>”. For example, if you do not enter a description, the first contour data operation is named “Contour Data1,” the second contour is named “Contour Data2,” and so on.
Weeding Factors
- Distance
-
Specifies the contour weeding distance. Enter the distance value or click
to select it in the drawing. - Angle
-
Specifies the contour weeding angle. Enter the angle value or click
to select it in the drawing.
Supplementing Factors
- Distance
-
Specifies the contour supplementing distance. Enter the distance value or click
to select it in the drawing. - Mid-Ordinate Distance
-
Specifies the contour mid-ordinate distance. Enter the distance value or click
to select it in the drawing.
Minimize Flat Areas By
- Filling Gaps In Contour Data
-
Specifies that small gaps in contours should be filled in.
- Swapping Edges
-
Specifies that a non-contour common edge shared between a flat triangle and a non-flat triangle should be swapped.
- Adding Points To Flat Triangle Edges
-
Specifies that a new point should be added at the midpoint of an edge shared between a flat triangle and a non-flat triangle.
- Adding Points To Flat Edges
-
Specifies that a new point should be added to edges that bridge two same-elevation data contours and are not in flat triangles.
- OK
-
Click to accept the contour values. You are then prompted at the command line to select objects (Polylines) from the drawing to define as contour data. When the objects are selected, the contour data is added to the surface definition.
