How do I edit the material strengths for PS Concrete I-Beams? They are grayed out and I can't change them. I am working in LEAP Bridge through OpenBridge Designer. I want to edit my span lengths and precast beam lengths in LEAP as well. Can that be done somewhere?
It sounds like you built this model with the BIM workflow? If so, then the material properties are controlled in OBM and will need to be updated in OBM, then pushed back to LEAP Bridge Concrete Superstructure tab (CONSPAN).
If you had used the Standalone workflow, you would be able to modify the material properties right there in the design program itself.
