For Steel bridge modelling, for the beam definitions, the only possible options are defining rolled or built-up shapes or defining Tub Girders.

It would be very beneficial to have an option or steel beams to define custom cross sections similar to custom beam types for concrete beams where custom cross sections can be created in Beam Libraries. At this time, it is not possible to model non-typical non-standard steel girder sections such as press brake tub girders or closed steel box beams.
