2Template OptionsTemplate Options are used to pre-configure settings used for point and component construction.Naming OptionsAffixesStep Options


3Template OptionsNaming 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.

Point Seed Name

Can be modified in the Dynamic Settings.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated

Template OptionsApply 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.

Do not use for individual Side-Neutral Components.

Enable when creating Templates.

Can be modified in the Dynamic Settings.


Template OptionsStep Options are used for Grid-Snapping when placing Points or Components.

Set values to 0 for no snapping.

Can be modified in the Dynamic Settings.


Point Constraint LabelsThe Constraint Label Value point 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.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated

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.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated

8Superelevation SettingThe point properties Superelevation Flag determines what points are made available when assigning the superelevation section to the roadway corridor.


Alternate SurfacesThe Alternate Surface point property supports the ability to generate a surface along any path.


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


Alternate SurfacesAlternate Surfaces cant contain any vertical lines as with any DTM surface.


12Alternate SurfacesUse common sense when creating your Alternate Surfaceis it constructible?


13Feature Name OverridesAvoids end condition transition issues and keeping track of many tie point and end condition component names.


14Feature OverridesPoint Property Feature Name Override changes the modeled linear point features to a common name.

Active Template Mode


Active Template ModeActive Template view option allows for easy isolation of individual points or components.Interactive right mouse click for editing, deleting, renaming, etc.PointsComponentsEnd Condition BranchesDisplay RulesParametric ConstraintsAlternate SurfacesPoint Feature DefinitionsComponent Feature Definitions


Component Display RulesAll Engineering is Subject to ConditionsComponent Display Rules Subject templates to Conditions


Component Display RulesComponent Display Rule PropertiesCompares the geometry of any points in a TemplateAny point in the component / template, not just EC pointsHorizontal, Vertical, Slope ComparisonsAt each Template DropEvaluate whether a Component is Displayed


Component Display RulesWalls not built in infinitely-varying dimensionsGood for initial engineering, quantitiesWalls built in discrete sizes


Component Display RulesTest an Independent ControlIf the Control Exists, use a special templatePoints that switch positionsMeandering Median Intermittent Engineering FeaturesWallsDriveways


22Component Display RulesExampleIf Pavement Matchline exists thenDo not draw Shoulder and End ConditionsCan be used at driveway and intersection seem lines


23Parent-Child Relationships for ComponentsA 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.


DemoUse 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.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated


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


Overlay ComponentsThe 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.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated

Overlay Components Top OptionsFollow 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.# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated

Overlay Components Bottom OptionsFollow Surface: The bottom of the component will follow the target surface at a distance below the surface as defined by the Surface DepthFollow Component: The bottom of the component will follow the component spine at distance below it as defined by the Component DepthFollow Lowest: The bottom of the component will follow the lower of the surface line or the spine minus the Component DepthFollow Highest: The bottom of the component will follow the lower of the surface line or the defined component line at the specified depths# | WWW.BENTLEY.COM | 2014 Bentley Systems, Incorporated
