In this box the performance of the program at the ends of the cross-sections cuts is defined when no terrain is available in them. A description of each option follows:
Cut. Selected by default. This proposes the cross-section profiles be cut should their strip width exceed the digital model definition or objects selected, in which case the profiles take on a width equivalent to the width entered or up to the point it is defined in the model.
Repeat. Using this option is recommended when there is excess strip width compared to the digital model and the surroundings are substantially similar to the last height obtained from the digital model. This is usually the case in terraced terrain or terrain having large flat surfaces, or when curved areas are cut in parallel fashion.
Interpolate. This option is used in order to complete the strip proposed when there is insufficient terrain in the strip width specified, the slope outside the working area is known and has similar gradients as those at the end of the profile. The program will interpolate using the slope of the last vectors cut until the height is raised to the profile’s final length at the right and left sides.
