The only ones i've ever done in OBM/LBS are real world single units (1-3 span units). I haven't had a bridge yet with multiple read world units that i tried to export from OBM to LBS as a single OBM unit. You'll have to test it out and try. I believe it will though.

Thank you for your clarification.

Thank you for your explanation. In my model, a unit is a group of continuous spans so that the bridge would have multiple units. If I follow your suggestion, will LBS be able to analyze and design simple and continuous spans in the same model?

As far as #2, if you have a bridge that is all steel just create it as a single "OBM" unit. I put that in quotes because the real world bridge term "Unit" and the OBM term "unit" can mean different things. Until we have the ability to model deck joints, i typically put an entire bridge type in a single "OBM" unit, and define the different girder units with different framing plans. This allows you to transfer your entire bridge with all of its units to a single analytical file. I basically look at the OBM term unit as "bridge type". Hope this helps.

Hi,

1. Currently, LBC works only with the reference line as the centerline of the abutment and because of this, he tries to translate the positions. This is something that we are working currently on to enhance in the next releases.

2. The transfer from OBM to LEAP/RM is unit-based, so you will be able to send one unit at a time. You will need to add manually the loads coming from the neighboring unit.
