Rollover in the gutter line?

[Coolmo]

Now that I've finally accomplished the superelevation part for the roadway, how do I get the gutter line in the Curb and Gutter to achieve a particular rollover slope as it makes it's way around the superelevated road?

There's nothing that I can find in the search for this. All I tried was "rollover" though.

I'm not real hip on highway design lingo, can you explain "rollover"?

The gutter slope as it pertains to the superelevation slope at a given station. "Rollover" is usually used with turn lanes and/or shoulders but it's the same idea for curb and gutter.

I've found that I can use the "UrbanCurbGutterGeneral" but that only (that I can tell) matches the superelevation slope of the outside lane. I need to give it a rollover slope to calc using the ouside lane slope. Is there an out-of-the-box subassembly that will do this?

I don't think so, but a custom subassembly could do this. We have one that automatically flips between catch and spill curb as the superelevation slope changes.

Yeah, the only way I've found to do this is copy the "UrbanCurbGutterGeneral" assembly, rename it to something else, and where it sets the gutter slope for each section in the VBA code, add or subtract the rollover slope that I want. I've modified the "UrbanCurbGutterGeneral" assembly (copys of) 3 times to add in a rollover percent for 2%, 4%, and 6% rollovers. It works great but I hate having to hack the VBA code to make different scenerios work.

can you send me the modified assembley

This type of gutter properrty is something we have been asking autodesk for since the beginning of C3D.
Use this link to let them know how much you need this property to be available without hacking the VBA code of some existing assembly.

Or add it to the AUGI wish list every year for the next decade and maybe we will finally get this property in a gutter assembly.
