There are heaps of nifty new feature line tools in Civil 3D 2009 that will make your grading life a whole lot more fun. One of my favorites is using a feature line as a corridor target. Think of all of the times you would love to grap elevations to drive your model but it seems redundant to make another alignment and a profile, especially when you already have a feature line drawn.
I made a feature line that reflects some lot grading. Perhaps this is a feature line that I am using to drive some grading objects- or some of the new relative elevation feature lines (a post on that one soon to come!)
I added a LinkWidthandSlope subassembly to my assembly which I will hook on to that yellow feature line. Note that ANY subassembly that will accept a target can do this- there are infinite possibilities!
There is a new user interface for choosing target alignment and profiles. Note the options- you can use alignments, profiles, survey figures, feature lines or polylines. Wow…
I add my feature line as both a “Width or Offset” target and as a “Slope or Elevation” target- and it works great! Any edits to my feature line will make my corridor out of date, and upon rebuild everything will ripple.
My mind is humming with ideas- how about yours?
**Note that feature lines that have been dynamically extracted from corridors (also new to 2009) cannot be used as targets in corridors. The possibility for circular references would be too hard to resolve.
Here is a peek at that delicious little option as food for thought:
