Meaning: The object was placed using an intersection relationship between two other objects and those other objects no longer intersect. For example, the top of a column was placed at the intersection of an elevation plane. Then, a beam was placed using the intersection of the column and the elevation plane as the beam's starting point. Sometime later, the column is moved such that the column end no longer intersects the elevation plane. The beam is placed on the To Do List with this message.
