15.4. Create from Alignment |
. With this option we have the possibility to create Setting out Control points from the control point coordinates of a particular alignment, with or without displacement.
First of all, the program requests the name of the horizontal alignment file or we select it on the screen, followed by the Initial Control point Number from which we begin to name the new control points. From this point the displacement from the horizontal alignment (negative to the left and positive to the right) is requested for each control point, in addition to the control point and the height of the new control point.
The new control point will be created at the position calculated from the horizontal alignment. If the control point entered does not belong to it, the following error message is displayed “ERROR: Control point does not belong to alignment”. The name consists of the characters “BR” followed by an index that starts with the number of the initial control point specified previously (for example, if we enter 1 as the initial control point, the control points will be named BR1, BR2...). The code will be the prefix “St” plus the value of the control point rounded to a whole number and separated by a comma (for example St180,-5).
The application will continue to request data for the creation of new control points until a null reply is given to the adjustment request.
