Tip: This symbol indicates the corridor is out of date. Right click and you can rebuild. They can also be set up to rebuild automatically. The advantage of auto rebuild is you get automatic feedback on design changes. The disadvantage is every time changes are made the corridor will take time to rebuild.

  1. In the corridor properties set the code set style to No Display and select all the feature lines > No Display
  2. Profile > Create Surface Profile > 25-Right-Trn-Ln alignment > Crdr-25-Setup-ETW surface > Add > OK
  3. Repeat for the left side
  4. Repeat for the 4thAve right and left sides

  1. Profile > Profile Creation Tools > Select the Profile view > <[Alignment Name]>-Prop > OK
  2. Tan Tan No curves > draw a line past the extents of the profiles (elevation doesn't matter here)

  1. Repeat for the other three corners
  2. Intersection > Create Intersections > Select the intersection point > 25-Right-TrnLn is main > deselect create offset alignments > Create

  1. Repeat for the other seven intersections

Comment: Now we will refine the profiles so they fit nicely within the slope ranges we have created

  1. Select a profile > Geometry Editor > Insert PVI
  2. Place it somewhere in between the slope ranges

  1. Repeat with the other curves
  2. Use the grip at the PVI to drag it to a place that fits well
  3. When there is a pronounced grade change you can smooth it out by adding a vertical curve
