Traffic lane 1D
Applicable to load 1D members.

Defining of the 1D traffic lane in 3D scene
#A - upon triggering the command "traffic lane 1D" - a selection of 1D beams is required. The traffic lane 1D is directly bounded with specific 1D members, and is defined by their geometry. In general, any kinds of beams (straight, circular, etc.) might be selected.
#B - the beam selection might be done by the box selection, selecting multiple beams at once. However, double check that the order of selected beams corresponds with the real physical order of the beams. This should not be a problem in case of straight beams, but in case of more complex geometry, e.g. several curved beams, selecting one by one (in order of the traffic trajectory) might be more robust to achieve correct selection order.
#C - it is also possible to define offsets of the trajectory at the begin and the end of whole the traffic lane. These areas will not be loaded by the mobile load at all. It is applicable for example when considering crane loads, where an end buffer stop device might be placed. Offset lengths smaller then the lengths of the begin and end beam might be input. If the offset length is desired to be larger than the begin / end beam, it is necessary to exclude this beam from the selection (step #B) and to define the offset on the previous beam.
#D - Double check the defined traffic lane is concisely depicted by the begin and end arrow, which determine the begin and the end of the area where mobile load will be applied. Avoid wrong order of the selected beam members.
Notes:
In general, the selected beams does not have to be in one (horizontal) plane. Beams might be reasonably declined (with some realistic angle), with different z-coordinate for the begin and the end points of the beams. It is however not expected to select columns, or in general members where the member x-axis is parallel with the GCS z-axis (or close to it), due to further logic of handling the mobile loads (which, if defined in z-axis direction within the Load Systems 1D are considered along the GCS z-axis).
