  1. Before you begin calculating superelevations
    1. Review WisDOT Standard FDM-11-10 5.3 Superelevations
    2. Use the WisDOT Design Criteria files
      1. Select alignment 25
      2. Contextual ribbon > Modify panel > select Alignment Properties
      3. Alignment Properties dialog box
        1. Design Criteria tab
          1. Use design criteria file > ... (ellipse) to browse
            1. Check box next to _WisDOT Design Criteria 2009.xml
            2. Open
  2. Apply superelevation to alignment
    1. Select alignment 25
    2. Contextual ribbon > Modify panel > Superelevation dropdown > select Calculate/Edit Superelevation
    3. Edit Superelevation - No Data Exists dialog box
      1. Message: The alignment does not contain superelevation data. What would you like to do? Select Open the superelevation curve manager
    4. Superelevation Curve Manager palette
      1. Select Superelevation Wizard
      2. Calculate dialog box
        1. Radio selected: Entire alignment
        2. OK
      3. Calculate Superelevation - Roadway Type dialog box
        1. Roadway Type
          1. Radio selected: Undivided Crowned
          2. Pivot Method: Center Baseline
          3. Next >
        2. Lanes
          1. Check box: Symmetric Roadway
          2. Number of lanes right: 2
          3. Next >
        3. Shoulder Control
          1. Outside edge shoulders
            1. Check box Calculate
            2. Normal shoulder width: 6.000'
            3. Normal shoulder slope: -4.00%
            4. Shoulder slope treatment
              1. Low side: Breakover removal
              2. High side: Match lane slopes
          2. Next > 
        4. Attainment
          1. Design criteria file: ... (ellipse) to browse
          2. Open dialog box
            1. Select _WisDOT Design Criteria 2009.xml
            2. Open
          3. Finish
    5. Superelevation Tubular Editor panorama
      1. Look for End Normal Shoulder and End Normal Crown, Begin Normal Crown and Begin Normal Shoulder
      2. Notice that the shoulder and lane transitions start and end at the same point.
      3. Also notice that the start and end station's slopes are different.
        1. To match the slopes, use WisDOT Alignment Superelevation Runout tool
        2. Ribbon > WisDOT Design tab > Design panel > Alignment dropdown > Alignment - Adjust Superelevation Runout
        3. Alignment Superelevation Runout dialog box
          1. Alignments with Superevlevation: select 25
          2. OK
    6. Return to Superelevation Tubular Editor panorama
      1. Slopes should match
  3. Create superelevation view
    1. Select alignment 25
    2. Contextual ribbon > Modify panel > Superelevation dropdown > select Create Superelevation View
    3. Create Superelevation View dialog box
      1. Specify superelevation display options:
        1. Go through the list and change each lane color, making each a different color.

      2. OK
    4. Select superelevation view origin: Select a place outside of the project area.

      Info: If there are warning symbols in the superelevation view, this means the transitions for the shoulders exceed what Civil 3D has built into the standards, but for our example they are correct.

  4. Save file when finished.
