In Openroads Conceptstation, the bridge is invisible

Could you make sure that you have the Bridge category displayed? (Nevermind, I have your dataset and we are looking into the issue.)

Of course yes! Because I never change the Bridge Category Display setting after placing the bridge.

Thanks for sending us the data. Development was able to review your data, and found that ConceptStation v10.00.06.45 does not like the back to back switchback spiral-curve-spiral (SCS) situation.  If you leave a short tangent section between ALL SCS curves on that alignment, the bridge will show up in the correct location. They will be addressing this defect in a future release.

Thanks for your response.
One suggestion for ConceptStation:

Adding Favorite Coordinate System into the context menu, because without the Favorite Coordinate System, you must search the Coordinate System every time when creating a project，obviously it is not convenient and is inefficiency.
On the contrary, you can find the Favorite Coordinate System setting in OpenRoads Designer and Power Inroads.

Hope you development team can do this, and can issue the next CS as soon as possible.
