The position of the support lines relative to the bridge axis is defined by a series of skew angles that represents the deviation angle from the direction normal to the alignment, with a range of [-45;45][deg].

There is the possibility to define the support behavior of an entire support line (i.e. one abutment or one pier). There is always support in vertical direction. Furthermore it can be defined separately if there is support in longitudinal direction and lateral direction.

Using the Reset supports name button you can go back to the initial naming of the supports.
