BEAM LAYOUT for curved and flared steel girders in Open Bridge Modeler

Hana,

You could toggle OFF "Same Beam Start/End Values and enter desired spacing at start and end 

Or you could use Aux Alignment option.  The beam centerlines need to be placed as Civil elements (they cannot be plain MicroStation lines).

The Aux Alignment option is an optional way to set the beams to a civil element.  You can draw civil alignments for each beam layout, then click on Add to Add the alignments to the Aux Alignments collection.  Then when defining the beams you can set the spacing reference to Aux Alignment and set the appropriate aux alignment.

Thank you, Dilip,

I've used the first option "Toggle off same beam start/end" and entered individual spacings at every support line. The flare part of the framing plan looks great, but I was not aware of the Aux Alignment option. That might be the answer for splitting the framing plan into 2 ramps.

Thank you very much for your advice...it's very appreciated.
