The possibility exists of grouping road design elements. With this command it is possible, for instance, to edit the length of one of them. The subsequent elements are adjusted, so that the end and initial points of consecutive elements continue to be the same.
For a group to be successful, it is necessary for the end point of an element to coincide with the initial point of the next element. One way of ensuring that this is so is to execute the ConnectElements command. It should also be taken into account that an element can only belong to one group.
The command requests the selection of a group of elements, the order of which is not important, and it may be selected via a window. In the case that any of the selected elements is already grouped, it will be required confirmation before continuing. Finally, it requests the initial Station value.
Starting from the initial end, the program will link one element with the next, as long as there is continuity between them. Otherwise, a list containing any errors found will be shown and with the possibility of drawing them on screen.
