Contour Line Preferences

Version française

The Contour Line Preferences interface in VisionLidar’s Civil Module allows users to define default contour settings, line styles, annotation formats, and decimal precision for each layer. Since preferences are set at the layer level, different layers can have individualized contour settings.

1. Key Features of Contour Preferences

✔ Set Default Contour Values – Define annotation intervals, step differentials, and minimum contour lengths.
✔ Customize Line Styles – Assign different line types for primary, secondary, and differential contours.
✔ Configure Annotation Text – Select text formats for elevation labels.
✔ Control Decimal Precision – Adjust the number of decimal places for contour annotations.

Default Contour Values

Option	Description
Annotation Interval	Defines the default spacing between annotations on a contour.
Step Differential	Sets the interval between differential contour lines.
Minimum Length of Contour	Specifies the minimum length a contour must have to be drawn.
Divide Curves by Annotation	Determines whether contours should be divided at annotation points.

Line Customization

Option	Description
Primary Contours	Selects the line type for primary elevation contours.
Secondary Contours	Defines the line type for secondary contours.
Differential Positive	Chooses the line style for positive elevation differentials.
Zero Contours	Defines the line type for zero-elevation contours.
Differential Negative	Sets the line style for negative elevation differentials.

Annotation Text Settings

Option	Description
Primary Contour Text	Selects the text type for primary contour labels.
Secondary Contour Text	Defines the text format for secondary contours.
Differential Positive Text	Chooses the text type for positive differential contours.
Zero Contour Text	Defines the text format for zero-elevation contours.
Differential Negative Text	Sets the text style for negative differential contours.

Decimal Precision Control

Option	Description
All Contours	Controls the number of decimal places displayed for contour elevations.

3. Customizing Contour Display

✔ Modify line styles to differentiate primary, secondary, and differential contours.
✔ Adjust annotation spacing to improve contour readability.
✔ Set decimal precision to ensure accurate elevation labeling.
✔ Enable/disable curve division for smoother contour lines.
