The purpose of this command is to represent boxes containing the information on singular and representative elements of each vertex of a horizontal alignment in ground plan view. The program asks the user to select a horizontal alignment for the drawing and then a window appears in which you can choose the style with which the alignment boxes are labeled.
Once the style has been selected, the program asks for the coordinates in which to insert the first labeling element. The scale can also be changed by selecting the appropriate option on the command line. The distance from the coordinates in question and the alignment will be used as the gap between the alignment and the other labeled elements.
