Hello,

I was wondering how 3D Viewer 7 handles
overpass sections created in Synchro.

Is there a way to account for changes
in elevation associated with these types
of facilities?

Thanks,

Hi Bruce,

Yes, 3D viewer will show roadway segments over and under based on the Z elevation. The elevation is set for the end point of the links, not for the link itself.

Thanks,

John.

Hi John,

I am trying to 3D Viewer 7 with Z Elevation as well. One funny thing I saw is vehicles are rolling on their front axle only. Looks like a stunt show on the street. Is this caused by drastic change in the Z elevation?

I have also noticed the phenomena of vehicles
doing some strange things (riding on the front or back axels) when I try to code z-elevation on some of my links. This problem is especially pronounced when I code a freeway interchange. Is it possibly related to intersecting links that violate the -20% angle rule?
