When working with intelligent cleanup for T intersections, the following rules apply:
- T-cleanup works by specifying a boundary wall segment for selected wall segments.
- The wall segments can be any distance apart, as long as they have a possible intersection.
- When an improper cleanup condition occurs, a tip displays to suggest possible solutions.
- Wall segments clean up when their respective wall justification lines intersect cleanly with each other.
- T-cleanup works for multiple wall intersections, but only one wall segment may be specified for the boundary.
- Select the wall segments to include in the wall cleanup.

- Select a boundary for T-cleanup.
T-cleanup works the same way for arc wall segments.
