Function	Description
Altitude	Minimum and maximum altitude to be imposed on the contours. The [Update] button gives us the altitude range of the loaded surface.
Interval	Determines the horizontal distance between the primary contours and the distance between the secondary contours. If you only want one, set the other to zero.
Contours type	The Polyline is an object made up of one or more straight segments connected to one another, and considered to be a single line. The Segment is an object made up of two points connected straight. The Spline is an object formed of a spline curve smoothed into a series of points within the specified tolerance. Note that with an higher tolerance, risks of line crossing increase. The Smoothing is a Polyline3D object for smoothing the polyline, a smoothing factor from 0 (not smoothed) to 100% (maximum smoothing) is specified. Minimal length of contour: Used to eliminate contours smaller than the indicated value.
Creation Method	By Triangulation: Uses triangulation to create the digital model of the land. By Nearest Neighbour: Uses a grid whose dimensions correspond to the box's fields to create the surface and interpolate the contours.
Annotation by line	Used to display each contour's altitude value on it. The annotations are placed by the lines defined in the following table.
Annotation by Interval	Used to display each contour's altitude value on it. The annotations are placed at regular intervals using the value indicated in the box that follows.

Annotations by line are placed along a polyline defined in the table at the bottom of the interface. The software will create a virtual line between each point in the table and will place the measurements along that line. If the points do not appear in the table after the points or lines have been selected, the surface must be saved.

If you want to show just one line at a specific height, simply place that height into the min. altitude and max. altitude box. However, you do have to make sure that the distance between the secondary lines is small enough to cover the desired height precision. For example, if you want the line to be at a height of 62.55, there will need to be a distance of 0.001 between the secondary lines, or one decimal place more than the requested height.
