Automatic adjustment is performed on a structural element, in relation to a neighboring structural element. Revit can automatically adjust the analytical model for beams, braces, structural columns, structural walls, structural floors, and foundation slabs so that they align more accurately. This behavior is based on the instance parameters of the elements and tolerance settings. For more information, see Analytical Model Continuity.
For auto-detection to take place, the analytical Adjustment Methods instance properties must be set to Auto-Detect for an element and its individual ends. This is the default justification method for all analytical structural elements. Automatic adjustment is then performed, as long as the Analytical Model of the adjacent element is within tolerance.
