Control points - TNSB3

11.7 Control points

For each created layer you can define a series of control points which will be used to calculate alignments deviations and to calculate the distances from these points to the cross sections.

Depending on the type of the point they can be used to calculate the horizontal alignment, the vertical alignment or both of them. More than one point must already have been defined or the calculations will not be correct.

Further on it will be explained how to use these points to calculate alignment deviation.

You can also generate control points automatically using the "Layers -> Generate control points..." menu.

In order to generate the control points, you will have to choose two points over the template, start and end point. The control points will be generated with a step separation.
