Maximum Shoulder Rollover disabled

[decurr74]

In the Superelevation Wizard, I need to assign a 4% maximum shoulder rollover, but the option is disabled.  I've tried different configurations in the Roadway Type and Lanes but none will activate the maximum shoulder rollover option.  What else do I need to enable to get this option to be enabled?

Assuming that you're calculating the shoulder slopes you should be able to set the High side to Default, then turn on the rollover control.

Yes, that is what I want to do, but those options are disabled.  What do I have to change to get those options enabled?

Change your High side treatment option from "Match lane slopes" to "Default slopes".  This will enable the maximum shoulder rollover option.

Shoulder slope treatments are also disabled.  How do I enable those?

The only way that I can get the shoulder treatment to be disabled is if the roadway type is set to one of the Planar options.  When you run through the superelevation wizard make sure that you use a crowned roadway..

Well, that is how to enable it alright.  Unfortunately, I am not working on a crowned roadway, it is a divided planar.  Hopefully I can trick Civil 3D using a crowned roadway to get the shoulder rollover without it screwing up the planar road that must be used.

Thanks for everyones time.

Perhaps someone from AutoDesk can add this to the long list of fixes for Civil 3D.
