Draw Super Elevation Diagram

This command draws the station and slope diagram for a template grade ID from data in a Template Grade Table (TGT) or Super Elevation Diagram (SUD) file. The Super Elevation Diagram (.SUD) file can be created with the Process Road Design or the Road Network commands.

The Super Elevation Diagram is a graphical representation of the change in cross-slope between the centerline and the left and right shoulders of a roadway. The diagram is typically drawn on a grid, similar to a profile, where the horizontal component represents the stationing of the roadway and the vertical component shows the cross-slope.

Select: Use this button (at the top-left of the dialog) to browse to and select the Super Elevation Diagram file (.sud) to be drawn.
Edge Code to Draw: Use this dropdown box to select the Template ID to be represented in the Super Elevation Diagram.
Link Diagram to File: This setting has 3 options: Off, Prompt and Auto:
   Off: This option will not re-draw the Diagram in the drawing if and when the Super Elevation Diagram (.SUD) file changes.
   Prompt: This option will notify the user that the Super Elevation Diagram (.SUD) file has changed and give the option of re-drawing the Diagram in the drawing.
   Auto: This option automatically re-draws the Diagram when the Super Elevation Diagram (.SUD) file changes.
Ref CL: Use the Select button to associate the Super Elevation Diagram (.SUD) file with a Centerline (.CL) file.

After the (.SUD) file has been selected, various details about the file such as "Slope Range", "Station Range" and "Total Length" are displayed below the Ref CL: setting.

Plot Settings

Horizontal Scale: Set as needed.
Vertical Scale: Set as needed.
Station Range to Draw: Enter "ALL" to draw the entire length of roadway or specify a range of stations.
Max Length/Diagram: Specify the maximum length of each diagram. If the "Station Range to Draw" is longer than the "Max Length/Diagram", additional diagrams will be stacked vertically above the first.
Space Between Grids: If the total length of the Diagram requires stacking of multiple Diagrams, this value specifies the distance between Diagram Grids.
Maximum Diagrams per Column: When multiple Diagrams are stacked, this number sets the maximum number of Diagrams per Column. If this number is reached, a second column will be created.

Grid Settings

Plot Grid: Select this option to have centerline and shoulder diagrams drawn on a grid.
Style: Select the Grid Style from several options. Grid Lines is the default setting. Other options are:
  Ticks Only: This setting draws tick marks for both the station increments along the bottom and the slope increments along the left edge of the diagram.
  Ticks and Dots: This setting draws tick marks for both the station increments along the bottom and the slope increments along the left edge of the diagram and draws a series of "dots" in a grid pattern across the rest of the diagram.
  Ticks and Checks: This setting draws tick marks for both the station increments along the bottom and the slope increments along the left edge of the diagram and draws a series of "+"-signs in a grid pattern across the rest of the diagram.
Grid Spacing: Set Vertical and Horizontal Grid Spacing as needed.
Layer : Enter the name of the Layer for grid lines, ticks, dots and checks or use the 2011_drawsud_ellipsis.png button to select the Layer from a list.
Color: Enter the Color for grid lines, ticks, dots and checks or use the 2011_drawsud_ellipsis.png button to select the Color from a list.
Draw Grid Text: Select this option to draw Grid Text for stationing and cross-slopes. Use the 2011_drawsud_ellipsis.png button to specify Grid Text settings such as precision, text size scaler, layer, text style, color and vertical/horizontal spacing.

Left Shoulder & Right Shoulder Settings

Layer: Enter the name of the Layer for the Left or Right Shoulder or use the 2011_drawsud_ellipsis.png button to select the Layer from a list.
Color: Enter the Color for the Left or Right Shoulder or use the 2011_drawsud_ellipsis.png button to select the Color from a list.
Linetype: Enter the Linetype for the Left or Right Shoulder or use the 2011_drawsud_ellipsis.png button to select the Linetype from a list.
Label Stations: Select this option to label the Station value at each slope change along the Left or Right Shoulder. Use the 2011_drawsud_ellipsis.png button to specify Shoulder Station Label settings such as precision, text size scaler, layer, text style, color and prefix or suffix.2010_superelevdiagram_stalabelsettings.pngLeft & Right Shoulder: Station Label Settings

Label Slopes: Select this option to label the Slopes along the Left or Right Shoulder. Use the 2011_drawsud_ellipsis.pngbutton to specify Shoulder Slope Label settings such as precision, text size scaler, layer, text style, color and prefix or suffix. The user also has the option of positioning the Slope label at the station of the Slope change or along the transition line.2010_superelevdiagram_slopelabelsettings.png

Center Line Settings

Layer: Enter the name of the Layer for the Centerline or use the 2011_drawsud_ellipsis.png button to select the Layer from a list.
Color: Enter the Color for the Centerline or use the 2011_drawsud_ellipsis.png button to select the Color from a list.
Linetype: Enter the Linetype for the Centerline or use the 2011_drawsud_ellipsis.png button to select the Linetype from a list.

Station and Slope Type Settings

Station Type: Select the desired format for Station. The options are: Percent or Ft/Ft.
Slope Type: Select the desired format for Slope. The options are: 1+00, 1+000 or 100..

Other Labels

Draw Transition Points: Enable this option and use the 2011_drawsud_ellipsis.pngbutton to configure and format the labels for Transition Start, Start Curve, End of Curve and End of Transition.2011_drawsud_labeltransitionpoints.png
Label Transition Points Dialog Box
Draw Axis of Rotation: Enable this option and use the 2011_drawsud_ellipsis.png button to configure and format the labels for the Axis of Rotation. The Axis of Rotation is a small icon displayed at the bottom of the grid at critical Super Elevation Points. The icon shows a cross-section view of the pavement slopes and a "+"-sign indicating the point of rotation for the Super Elevation.

Draw Non-Linear Transition Points: Non-linear transition points are drawn when the rate of change of elevation is not constant at the point where the Super Elevation starts or ends. Enable this option and use the 2011_drawsud_ellipsis.png button to configure and format the labels for Start of Curve, End of Curve and Point of Intersection.2011_drawsud_labelnonlineartransitionpoints.png
