With the introduction of some exciting new superelevation functionality in the 2012 release of Civil 3D, there is a new subassembly included in the tool palette that will not only take advantage of the new functionality, but greatly simplify things in the process. This subassembly is called the LaneSuperelevationAOR subassembly and has a lot of great features – find out what they are after the jump.
At first glance, the subassembly looks identical to the LaneOutsideSuper and LaneInsideSuper subassemblies, two of the most versatile and widely used subassemblies in the catalog. However, if we dig into the properties, you can really see the differences:
There appear to be many more options here than in the old subassemblies. Of course, the side, width, default slope, and depths are still the same. But some new additions include an option to choose which superelevation you use (if any) – that’s right – this subassembly COMBINES the functionality of the LaneOutsideSuper, LaneInsideSuper, and LaneTowardCrown subassemblies and makes them obsolete! Don’t panic, though – your legacy drawings with the old subassemblies will still work and you still have access to the subassemblies (although I can’t figure out why you would.)
Two other options let you set the slope direction (away from crown or towards crown) and Potential Pivot point – this will let you use the lane for alternative pivot points with the new superelevation options.
Enjoy this new powerful subassembly!
