You can delete a junction object, erasing it from the drawing and removing it from the Junctions collection in the Prospector tree.
When you delete a junction object in the drawing, the following are deleted:
- the junction object, and its label, in the drawing
- the junction object in the Junctions collection in Prospector
The following components associated with a junction object are not deleted when you delete a junction object:
- the following 2D geometry components associated with the junction object: intersecting alignments, offset alignments, corner radius alignments
- the following other components associated with the junction object: offset profiles, corner radius profiles
- If you created a new corridor object inside the junction area, this corridor object is not deleted when you delete a junction object. You must delete this corridor object manually, if desired.
You can use the following methods to delete a junction object:
- In the drawing, select the junction object, and delete or erase it.
- If you delete one or both of the intersecting alignments that create the junction, then the junction object is automatically deleted.
- In the drawing, if you move one or both of the intersecting alignments that create the junction so that the alignments no longer intersect, then the junction object is automatically deleted.
Deleting Junction Object Dependent Components
It is important to understand the following behavior associated with deleting objects that junction objects depend on.
- Centerline Profiles: If any of the centerline profiles associated with the junction are deleted, then the corner radius profiles will become static (no longer a dynamic profile). Accordingly, the junction corridors will be updated. This behavior is similar to how a corridor reacts to its profile gradient line, or when a centerline profile is deleted. In this scenario, the junction object still exists (is not deleted), with just horizontal geometry.
- Offset Alignments: If an offset alignment associated with a junction object is deleted, and that offset alignment has a corner radius alignment attached to it, the corner radius attached to that offset alignment is not deleted; however, the corner radius alignment is no longer dynamic to the junction object. It becomes a static corner radius alignment, meaning that if you move the junction object, the now static corner radius alignment does not move. The same is true for the profile associated with the corner radius alignment. It becomes a static (non-dynamic) profile.
- Corner radius Alignments: If the corner radius alignments or profiles are deleted (using AutoCAD Delete), then the junction area corridors based on those baselines are also deleted. If only the profile is deleted, then the corridors based on those profiles are moved to zero level. The junction object still exists. Deleting the corner radius does not automatically delete the profile associated with it; however, if you delete the corner radius, the corner radius profile becomes static.
- Assemblies: If any of the assemblies used the junction are deleted, and the corridor is set to “Rebuild Automatic”, then the corridor regions that use the deleted assemblies are set to <None>. This creates an empty corridor even though corridor regions still exist. You can use the Recreate Corridor command to download the assemblies from the source location into the current drawing, and this recreates the corridor regions.
