This option has been implemented in order to interpolate a certain number of contour lines between two given contours without needing the digital model.
The program will execute the algorithm previously set in the program configuration (see Contours Lines section in the Customization Manual).
The command has the possibility of interpolating between complete contour lines or by selecting the initial and final points of each of the original contour lines in order to interpolate partially. The following message is shown:
Select <Polyline>/Vertices:
If a polyline is selected directly, it is understood that one wishes to interpolate complete contours. If the second option is chosen, four control points are requested.
The graphic below shows an example of this command in use:
Before executing the command:
After interpolation:
A brief description of the two algorithms employed is given below.
