  3. Template Options • Template Options are used to “pre-configure” settings used for point and component construction. • Naming Options • Affixes • Step Options

  4. Template Options • Component Seed Name • From Feature Definition • Specify • Point Seed Name • Can be modified in the Dynamic Settings. • Naming Options are used to set the default seed name for Points and Components. This seed name can always be changed from the initial default setting during the creation of the points and components.

  5. Template Options • Do not use for individual “Side-Neutral” Components. • Enable when creating Templates. • Can be modified in the Dynamic Settings. • Apply Affixes are used to set the default left and right side prefix or suffix for point names and components. • Assures unique naming for all points and components when mirroring or reflecting from side to another.

  6. Template Options • Set values to 0 for no snapping. • Can be modified in the Dynamic Settings. • Step Options are used for “Grid-Snapping” when placing Points or Components.

  7. Point Constraint Labels The Constraint Label Valuepoint constraint property allows the constraint value to be overridden when processing the corridor. These constraint label values are referred to as Parametric Constraints. Allows the user to adjust the constraint(s) to match the current design standard requirements without having to create a new component or template.

  8. Point Constraint Labels • The Point Constraint Label – Parametric Constraint allows for a Constant-Value override or a Tapered-Value override • Can be set for a station range or the entire length of the Corridor.

  9. Superelevation Setting The point properties Superelevation Flag determines what points are made available when assigning the superelevation section to the roadway corridor.

  10. Alternate Surfaces The Alternate Surface point property supports the ability to generate a surface along any path.

  11. Alternate Surfaces Use the Active Template mode to identify Alternate Surfaces. Do not use exact vertical edges.

  12. Alternate Surfaces Alternate Surfaces can’t contain any vertical lines as with any DTM surface.

  13. Alternate Surfaces Use common sense when creating your Alternate Surface…is it constructible?

  14. Feature Name Overrides Avoids end condition transition issues and keeping track of many tie point and end condition component names.

  15. Feature Overrides Point Property Feature Name Override changes the modeled linear point features to a common name.

  16. Feature Overrides Component Property Feature Name Override changes the modeled component surface features to a common name.

  17. Active Template Mode

  18. Active Template Mode • Active Template view option allows for easy isolation of individual points or components. • Interactive right mouse click for editing, deleting, renaming, etc. • Points • Components • End Condition Branches • Display Rules • Parametric Constraints • Alternate Surfaces • Point Feature Definitions • Component Feature Definitions

  19. Component Display Rules All Engineering is Subject to Conditions Component Display Rules Subject templates to Conditions

  20. Component Display Rules • Component Display Rule Properties • Compares the geometry of any points in a Template • Any point in the component / template, not just EC points • Horizontal, Vertical, Slope Comparisons • At each Template Drop • Evaluate whether a Component is Displayed

  21. Component Display Rules • Walls not built in infinitely-varying dimensions • Good for initial engineering, quantities • Walls built in discrete sizes

  22. Component Display Rules • Test an Independent Control • If the Control Exists, use a special template • Points that switch positions • Meandering Median • Intermittent Engineering Features • Walls • Driveways

  23. Component Display Rules Example…If Pavement Matchline exists then • Do not draw Shoulder and End Conditions • Can be used at driveway and intersection seem lines

  24. Parent-Child Relationships for Components A component has the ability to be either a parent or a child of another component. When a parent is displayed, the child or children will be displayed.

  25. Demo Use Null Point to seek a matchline. Used for Driveways, Sideroads, etc. Do not draw shoulders and end conditions when matchline found. Component Display rule on the shoulder comparing the distance between two null points. Parent-Child relationships on the end conditions setting the shoulder as the parent.

  26. Overlay Components An Overlay/Stripping Component has special properties to follow the designed component slopes or the active surface or both.

  27. Overlay Components The top or the bottom or both may vary in position, depending on where and how the surface intersects it. The linestring from which the component is defined is referred to as the “spine.” We define a string of points (or “line” or “open shape”) to set the geometry of the component. The Top is always the top limit of the component and the Bottom is always the bottom. This “spine” is not necessarily the top of the component, but will always be between the Top and the Bottom of the component.

  28. Overlay Components • Follow Surface: The top of the component will be draped along the top of the target surface. • Follow Component: The top of the component will follow the component spine. • Follow Highest: The top of the component will follow the higher of the surface or the spine. Top Options

  29. Overlay Components • Follow Surface: The bottom of the component will follow the target surface at a distance below the surface as defined by the Surface Depth • Follow Component: The bottom of the component will follow the component spine at distance below it as defined by the Component Depth • Follow Lowest: The bottom of the component will follow the lower of the surface line or the spine minus the Component Depth • Follow Highest: The bottom of the component will follow the lower of the surface line or the defined component line at the specified depths Bottom Options

  30. Overlay Components Depth Measured from Active Surface – Ignores Profile Top Option = Follow Surface Bottom Option = Follow Surface Component Depth = 0.0 Surface Depth = +0.083 • Nominal Depth Milling Only • Example (1” Depth Following Existing Ground)

  31. Overlay Components Component Depth Measured from Active Profile Top Option = Follow Surface Bottom Option = Follow Component Component Depth = +0.1667 Surface Depth = +0.0 • Slope Correction Milling Only • Example (2” Depth BELOW PROFILE Correcting Cross Slope)

  32. Overlay Components • Nominal Depth Milling + Crown Correction Leveling Binder • Requires Two Components • Example (1” Depth Following Existing Ground + Leveling Binder to Correct Cross Slope) • Top of Leveling Component uses Active profile

  33. Overlay Components • Slope Correction Milling + Slope Correction Leveling Binder • Requires Two Components • Example (2” Depth BELOW PROFILE + Leveling Binder to Correct Cross Slope) • Top of Leveling Component uses Active profile

  34. Overlay Components Once the Overlay Template is designed and placed in a Corridor, use the Overlay Vertical Adjustment Tool to design the adjusted design profile.
