Template Details: End Conditions
Create Template - End Conditions
End Conditions within the FLH Template Library have different properties. The following folders containing specific End Conditions have been pre-defined within the library: Daylight Slope, Ditch, Fill, and Slope Tables. When using the template library, some properties of these end conditions can be revealed by selecting the Active Template tab and by using the Display options (as shown in the image below).
End Conditions are template components which are used to model cut and fill treatments. They are added to the end of simple, constrained, and unconstrained components. End Conditions are created like other template components. End Conditions consist of template points and individual components, and appear as line segments. End Conditions are different than simple, constrained, unconstrained, null point, and overlay/stripping components because they have the ability to target surfaces, elevations, alignments, and surface features.
Target Types are defined only for End Condition components, and are a property of that component. Target Type specifies the type of target the End Condition is seeking.
- Surface - Targets the active surface or any specified surface.
- Elevation - Targets a particular elevation.
- Feature XY - Targets the horizontal location of a feature of a particular surface.
- Feature Elevation - Targets the vertical location of a feature of a particular surface.
- Feature XYZ - Targets the location of a feature of a particular surface. Overrides the slope constraint of the End Condition segment to seek the feature.
- Alignment XY - Targets the horizontal location of a particular alignment.
- Alignment Elevation - Targets the vertical location of a particular vertical alignment or, in the absence of a vertical alignment, uses horizontal geometry elevation.
- Alignment XYZ - Seeks the location of a particular alignment. Overrides the slope constraint of the End Condition segment to seek the feature.
- Style XY - Targets the horizontal location of a matching style assigned to a feature or alignment.
- Style Elevation - Targets the vertical location of a matching style assigned to a feature or alignment.
- Style XYZ - Targets the location of a matching style assigned to a feature or alignment.
Priorities for End Conditions need to be established. Each condition will be tested in a specific order. That order is called the priority, which is numeric, and is assigned during end condition creation. The most desirable are assigned the lowest priority numbers. The desirable condition, and the first condition to be tested, is a priority of 1. The next condition to be tested will have a priority of 2, and so on. Priority is used when more than one end condition starts at the same point.
Properties for End Condition Settings need to be considered when applying end conditions. These settings need to be enabled or disabled to obtain the desired result.
- Check for Interception - Check on to search for a specified target. Check off to create the line segment at its full width regardless of whether it intersects the target provided that one of the segments connected to this segment successfully intercepts a target.
- Place Point at Interception - Checked on for a point to be placed at the location of the interception. Check off to create the line segment at its full width provided that one of the segments connected to this segment successfully intersects the target.
- End Condition is Infinite - Checked on for the line segment to automatically extend to intercept the target. Check off to only extend to its maximum constraint to meet its target (which applies only to the last line segment in an end condition).
- Do Not Construct - Checked on and the end point of the line segment will be used as a reference point to find a subsequent point. The point will be solved like any other end condition point but it will be skipped when drawing the final component segments. This is normally checked off and is only used for Targets the horizontal location of a feature of a particular surface.
Testing End Conditions prior to and during end condition creation will simulate how the end conditions will behave during modeling, without using the Roadway Designer. Non-solved end conditions, and their child components, are displayed in dashed lines. Normal components and solved end conditions are displayed as solid lines. The display has all the standard windowing commands and scrollbars
