About Editing Intersections

You can edit intersections using commands available from the ribbon, from right-click context menus, or by editing the objects directly in the drawing using grips.

Changes Managed by the Intersection Object

The following types of edits can be performed by making changes directly to components that are controlled by the intersection object:

• Change the parametric values of the intersection object definition, such as nominal offsets/cross slopes, curb return profile rules, and corridor regions
• Change edge offsets from parametric (nominal offset) values to predefined alignments
• Change edge offset profiles from parametric (nominal cross slopes) to predefined profiles
• Change (intersection) rule-based dynamic offset alignments and dynamic profiles to static and then make edits to them
• Change association of assemblies to one or more of “dynamic corridor regions”
• Change the frequency that the assemblies are applied to the dynamic corridor regions

Typically you will need to update corridor regions after making these types of edits to intersection objects. When an update is necessary, an out-of-date icon is displayed in Prospector for the corridors in the intersection. If you have Update Regions Automatically turned on for the intersection object, then the corridor regions are updated automatically after these types of edits.

Changes Not Managed by the Intersection Object

While you can make the above types of changes by manipulating components that are controlled by the intersection object, it is also possible to make other types of changes that are not directly managed by the intersection object. For example, you can make the following types of changes that are not managed by the intersection object:

• Change the intersection area corridor region extents and or add more regions within the intersection extents
• Change the corridor targets in the intersection for the edge offsets and profiles
• Edit corridor parameters in the intersection area regions using the Corridor Section View Editor

Because these last three types of changes do not modify the intersection object definition, it is important to understand that if you do make these types of changes, they could be overwritten or ignored if you update the corridor regions in the intersection, or if you recreate the intersection.

Note: When you edit the horizontal or vertical geometry of the intersection object, the road that is specified as the secondary road is automatically adjusted to accommodate the horizontal and vertical position of the road that is specified as the primary road.

The sections that follow describe how to make various types of edits to intersection objects.
