Template Editor

The Template Editor routine permits "daylight" (or grade) segments to be created and modified and used (for example) in commands such as Stake Slope, Stake Road, Elevation Difference by Road Design Files, etc.

Note: More comprehensive template design (including options for curb/gutter "plates", medians, designated ditches and material subgrades can be generated in other Carlson products (e.g. Carlson Civil which is part of the Carlson Select Suite and/or Carlson Construction which is part of the Carlson Takeoff Suite) whose Grade segments and Cut/Fill slopes can then used in SurvPC.

Note: Template geometry can be graphically inspected through the Draw Template command.

• Clear: (icon) Located to the immediate left of the Orange Back Arrow is the Clear button that empties all information from the dialog in preparation for entering a new template.
• Right Side Same as Left: When enabled, a symmetrical template can be created by entering left-side data geometry.

  Note: For asymmetrical templates, turn off the toggle and select the appropriate Left/Right SURFACE indicator label to establish which side of the template is active.

• Distance: The horizontal distance of the Grade segment.
• Slope: The value and method used to determine the change in elevation of the Grade segment.
• ID: A unique (per side) identifier that describes the end of the Grade segment.
• Add: Use this button to Add a Grade segment to the end of the segment list.

  • Slope: Indicate the method and value for the Grade segment.

    Note: Slopes that drain away from the centerline are entered as negative values.

  • Distance: Indicate the horizontal distance of the Grade segment.

    Note: The Distance must be > 0.

  • ID: Indicate the unique identifier that describes the end of the Grade segment.

    Note: Common practice is to use a short (two- or three-character, with or without a qualifying numerical identifier) to identify the end of the Grade segment.

• Edit: Use this button to Edit the value(s) of the active Grade segment.

  Note: The specialty segments of Curb and/or Median that can be produced by (for example) Carlson Civil cannot be edited in SurvPC.

• Remove: Deletes the active Grade segment from the list.
• Up/Down: Permits the actively selected segment to be moved Up/Down in the list, respectively.
• Cut/Fill: Use this button to establish the slopes that emanate from the end Grade segment that will subsequently intersect existing ground when the side of the templates is in Cut or Fill.

  Cut/Fill

  

  • Right Side Same as Left: When enabled, a symmetrical Cut/Fill slopes can be created by entering left-side data geometry.

    Note: For asymmetrical slope treatments, turn off the toggle and indicate the desired Left/Right Cut/Fill Slope values.

  • Percent/Ratio: Indicate the method used to represent the Cut/Fill Slope values.
• Super: Use this button to establish the superelevation limits (if applicable).

  Super

  

  • Divided Road: When enabled, the Transition from Normal to Super (Inside Edge) controls will be enabled to permit additional superelevation control for divided roads.
    • Transition from Normal to Super (Inside Edge): When enabled, identify by Template Point ID (e.g. EP) or parametric-based equations (e.g. EPI+2 or EPI-2) where superelevation pivot points (typically, inside edge of pavement) should occur for the High/Low Pivot Points (PP) for a divided roadway template.
  • Transition from Super to Normal (Outside Edge): identify by Template Point ID (e.g. EP) or parametric-based equations (e.g. EP+2 or EP-2) where superelevation pivot points (typically, inside edge of pavement) should occur for the High/Low Pivot Points (PP) for an undivided roadway template.
  • Max Percent Slope Difference: Indicate the maximum allowable grade difference between the segments on either side of the Pivot Point. Once this maximum allowable slope difference is achieved, template segments outside of the pivot point will elevate as a unit relative to the grade segment inside the Pivot Point.
  • Low Side Grades to Match Greater SUP Slope: This option applies to the template grades that are outside the superelevation low Pivot Point. When the superelevation slope becomes steeper than these outside grades, these grades are then adjusted to match the same super slope. You can adjust up to two additional grades past the superelevation pivot point. For example, consider a template where the superelevation pivot point is the EP grade and the next grade is a shoulder (SH) and you desire this first segment to adjust with the EP grade. Set the control to "1". If the regular SH slope is -4%, the SH will stay at -4% through the superelevation until the superelevation rate becomes greater than 4% (at this point, the SH crown has been removed). If the superelevation rate of the EP segment continues to 6%, the SH segment will steepen to 6% to keep the SH crown removed.
• Load: Launches the standard File Selector that permits an existing *.TPL file to be inspected..
• Save: Launches the standard File Selector that permits the current template geometry to be saved to a new or existing *.TPL file.

Note: Templates in SurvPC have only one surface; the surface you are staking. To stake out a subgrade, you could enter the surface grade information and use a vertical offset in Stake Road or enter the subgrade surface directly as a template in conjunction with the subgrade profile.

Subgrade Example

Consider the dimensions of the example template shown below:

Let's focus on the subgrades that are built by the dozer, motor grader or trimmer. There are only three distinct grades to consider:

1. 12' at -2% (subgrade at bottom back of curb, BC)
2. Vertical for 13½" (top back of curb, CB)
3. 6' at 4% (shoulder location from where Cut/Fill projects, SH)

To obtain this subgrade template from the finished grade template shown above, we would:

1. Edit the first grade to change the 10' offset to a 12' offset and changes its description to BC, then
2. Delete the Curb segment, then,
3. Add a Grade segment to account for the 13½' (1.125') vertical segment as illustrated below:

   

   Note: For the Vertical method, some positive horizontal distance (e.g. 0.001') must be entered.

4. Move the segment Up in the list. The list of grade segments should resemble the following:

   

5. Save the template to a new file name (e.g. Subgrade.tpl).

Ditch Example

For roadway projects that utilize drainage ditches, four template definitions may be necessary for slope staking:

1. Cut Left, Cut Right
2. Cut Left, Fill Right
3. Fill Left, Cut Right
4. Fill Left, Fill Right.

The appropriate template can then be used for any condition. Shown below is a continuation of the Subgrade Example above with the the Fill Left, Cut Right (ditch on right-side) with a 3:1 foreslope and 4' wide flat-bottom ditch:

Using this template, cut slopes on the right side of the road will find the pivot at the base of ditch, while fill slopes on the left side of the road will pivot from the edge of shoulder.
