Roundabouts using Vehicle Tracking

[M_c3d]

I'm creating a roundabout using the vehicle tracking roundabout wizard within civil 3d 2017 (great tool and its something that is badly missing from Civil 3d.

I have used alignments and vertical profiles to set longitudinal gradient of the centre line of the approach roads, which has all worked fine.

The problem I'm having is i cant see where to set the cross fall / camber / slope of the road to having it falling to either side.

At the moment it is using the vertical profile of the road for the side profiles but other than using a edge vertical profile there must be a way to set this?

Any Ideas?

Thanks

Try using Edit Roundabout, 3D Corridor, Rebuild Now. This will make a corridor. You can then edit the assemblies to set the crossfall you want.

Hi,

That is how I tried it but it seems to ignore the assemblies and has a flat gradient?

Thanks

The levels and grades tabs on the roundel and on each approach arm allow you to control cross-fall in the roundel region and weather not not to use "Stockdale" style crown lines and a tilted plane on the roundel. I have raised a defect regarding setting the road cross-fall at the blend point on the incoming road.

Any news on the crossfall near the blend point issue? IT seems to be present even in R2018? I have to adjust the crossfall by adjusting nearby cerb profiles towards the incoming streets. Not optimal.
