Dominant Elements in Concrete Joins

This information is "ripped" from the WikiHelp topic...

Whenever elements that use concrete for their material interact with each other one element retains its geometry while the geometry of the other element sharing the join is cut to create the appearance of a single form. For example structural floors and walls possess dominant geometry characteristics and always maintain their geometry when sharing a join with other elements. Because of this, they will not automatically join with one another. These other concrete elements behave as follows.


These join behavior rules cannot be changed and it is not possible to disable the automatic joining of geometry. It is possible to manually change this condition using the UnJoin Geometry tool.

While were at it these are the valid combinations for concrete elements to join, in other words they may automatically join with one another.
  • beam to beam
  • beam to column
  • isolated foundation to isolated foundation
  • isolated foundation to wall foundation
  • structural floor to beam
  • structural floor to column
  • structural floor to slab edge
  • wall to beam
  • wall to column
Remember that joined geometry may have an impact on project performance.

Please note that in Revit 2014 you can change the join order: http://wikihelp.autodesk.com/Revit/enu/2014/Help/0001-Revit_Us1/2854-Tools_an2854/2906-Editing_2906/2995-Modifyin2995/3009-Joining_3009/3011-Switch_J3011
