I have been trying some different things with building my model. It is the same model from my original post, but I will include some screenshots below and my Roadway folks changed the alignment on me. In the OBM model the right barrier seems to sit where I placed it. When I transfer to LEAP Steel, it seems to move and follow the roadway alignment. Is there a fix for this?

in OBD, there are two workflows, the BIM workflow and Standalone workflow.

In the BIM workflow, all geometric changes need to occur within OBM. In the Standalone workflow, you can make changes to geometry in the analytical products as well as in the modeler.

It took me a while to get back to this project, but I did this and it worked in the OBM model. When I moved the model to LEAP Steel, the barrier follows the curve, but the deck appears to remain straight. I have the barrier placed along the front face of the barrier/gutterline. If i move the barrier so it is placed along the edge of the deck, it appears to fix it. i"d prefer to place it by the gutterline, but I can work around that if I need to.

I do have some additional questions though. Once the model is built in OBM and transferred to LEAP Steel, it appears that I lose some functions. I don't see anyway to revise the actual design, beam size, etc. I have a hunch that I am missing something somewhere because if this the case, I don't see a point to building the model in OBM. Also, let say I wanted to skip the OBM model and go straight to LEAP Steel and LEAP Concrete. My next question is similar to my original question. Is there a way to build the model in LEAP Steel/Concrete and maintain a straight deck when the roadway alignment is curved slightly?

This is a small structure with the PT only a few feet onto the structure. At this point, I am just trying to get familiar with the software.

Can you attach a plan view drawing showing the alignment and bridge ?
