Tool

Purpose

End Condition Exception

Define end condition exceptions, which are used to modify the behavior of an end condition solution without requiring the use of additional template drops. When an end condition exception is added, it must be edited to change its behavior.

Parametric Constraints

Constraint value overrides for specified station ranges. When you select a parametric constraint from the list, all the points that it is being applied to are highlighted in the cross section view.

Target Aliasing

Used so that one corridor can target the solution of another corridor when working with multiple surfaces.

Corridor Referencing

Used to add (or subtract) graphic elements from a corridor.

Corridor Clipping

Allows you to remove areas of overlap when working with multiple corridors or a single corridor and MicroStation shapes or meshes. For example, in a corridor intersected by a crossing roadway, clipping would be used to remove all overlapped features within the intersection.

Overlay Vertical Adjustment

At each processed station, this command determines the ideal PGL point based on the input criteria and the distance from the top of the template to the existing ground. Each existing ground vertex in the cross section will be tested by measuring the vertical distance between that ground point and the top of the template.

Secondary Alignment

Used to modify the direction of cross section processing. By default (at any given station), the cross section is created orthogonal to the corridor alignment. If a secondary alignment exists, then that portion of the cross section which lies outside the secondary alignment will be orthogonal to the secondary alignment instead of the main alignment.
