You may need to edit offset alignments after an intersection is created. You can change the offset value, or select a different alignment to use as the offset.
For example, you can use the Edit Offsets command on an existing intersection object to change the parametric value of the intersection, or you can select a different offset alignment, using one from the current drawing. You can also grip edit the dynamic offset alignment after it is created.
It is also possible to edit offsets for incoming and outgoing roads by editing the corridor parameters, although this is not typically the preferred method. For example, the offsets can be changed by overriding offsets at one or more stations, or by overriding target parameters for incoming and outgoing lanes.
This procedure describes how to widen a road by editing the offset alignment definition on an existing intersection object.
Notice that when the Use An Existing Alignment property is set to No, the Alignment Name property is read only. Notice also how the Offset Value property is set, and that it is currently editable.
Notice that the Offset Value is set to *Varies* if the alignment is not a dynamic offset alignment based on a centerline. Otherwise, the Offset Value specifies the offset value of the attached dynamic alignment. This control is disabled (read only) in both cases.
This procedure describes how to widen a road by grip editing the offset alignment that is controlling an intersection.
