Civil data for brdge

I have prepared roads alignment using civil tools (see my previous post). But when I was trying to add the bridge the message “Road and Bridge alignment should be different” is being displayed.

Comparing my model with Segmental Bridge example I have noticed that within example road alignment is described “in plan” and within my model descriptions were "moved" to profile. Is thist the reason I can’t add a bridge ? If so, how to fix it? It wasn’t my intension to do it this way it “just happened”. I haven’t found any example with making road alignment within OBM, so I can’t find where did I go wrong. I will be grateful for and advice.

  • Bogdan ... you only need both alignments if the road and bridge alignments are not coincident.  For example a straight bridge on a curved alignment. In that case, the curved alignment would be the road alignment, and the straight alignment and profile will be the bridge alignment.  

  • Hello Steve,

    Thank you for your advice. To be honest I'm OBM greenhorn, so there is still more qestion marks than answers. But somehow I added to bridges but I can’t catch the concept of working with them.

    First doubts are Civil Data:

    1. I have prepared a few alignments but I can see only one in explorer
    2. For the Horizontal alignment S7-CL three profiles are displayed. why? – I made only one
    3. How to display all defined alignments?

    Another question refers to bridges:

    In my case only flat (horizontal) alignment can be pointed as a bridge alignment. But when I point it and try to add support lines program crashed.

    I suppose 3D alignment representation should be pointed, but I can’t do it – message “Element not valid for this tool” is being displayed. Is the any way to make 3D alignment available for bridge definition?
