The program’s behavior concerning cut ends of the cross-sections is set in this box when there is no terrain. Each of the options is described below:
Cut. Selected by default. It proposes the cross-sections to be cut should their strip width exceed the digital model’s definition, or the objects selected, in which case the profiles take on a width equivalent to the width entered or up the point the model is defined.
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 terrain having large flat surfaces, or when curves in are cut a 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-hand and left-hand sides.
