About Feature Line Site Properties

Use the Feature Line Site Properties to view the combined statistics for all feature lines in the current site and to resolve crossing feature line elevations by specifying style priority.

Statistics

The Feature Line Site Properties dialog box Statistics tab displays the combined statistics for all feature lines in the current site. The Grouped Statistics tab groups the site statistics by style and layer. The statistics cannot be edited.

Feature Line Style Priority

The Feature Line Site Properties Options tab allows you to control the feature line style priority. The style priority is used to control the feature line elevations at split point.

When two features, such as feature lines, lot lines or survey figures cross and neither feature has a geometry point at that location, a split point is created. You cannot edit this point directly, as it is controlled by the grades of the two crossing segments which must have the same elevation at the crossing point. If the two elevations are different, a grade break is inserted into one to match the elevation of the other.

You can assign a priority to feature line styles so that when two feature lines with different styles cross, the one with the higher priority will set the elevation. Feature lines without a style have the lowest priority.

Note: If two feature lines have the same style or no style, then the feature line that is modified last becomes dominant, causing the other feature line to break at that point. The last-edited feature line controls the elevation at that point, which can cause undesirable results. To control the elevation at that point, use the Insert PI command to create a vertex at the split point.

Important: Feature lines without a style applied can also assume the elevation of an alignment if they cross, resulting in a vertex of zero at that point. If you find that any feature line has an elevation of zero be sure that you have applied a style to that feature line. A feature line with a style applied will always take priority over an alignment, and will not assume the alignment’s elevation.
