I have a multi-span model in LEAP and I have defined the substructure goemetry in the global model. However, when I go to substructure analysis, the cap dimensions are zero and I can't change them.
I would suggest you to model the bridge using ABC wizard .
Or please go to Substructure Module directly and click Substructure button and start modeling the substructure geometry.
I would NOT suggest you to model the bridge in GEOMETRY TAB --> Bridge Parametric Layout option.
