Custom profiles can be created in Tekla Structures.The extension can create layout points along all part edges, additionally it comes bundled with a plugin called EdgeMeasurement which can be used to create layout points along specific part edges only.This tool creates consecutive beams, a polybeam or an item with any profile and can be used for bridge modelling.
