ElemntJoiner pro allows you to create automatic junctions between several Autodesk® Revit® solid elements. You can do join the operations with the following methods:

Select categories in the fist section and elements of another category in the second section, and do all the joint operations you need between Elements 1 and 2. For example, (you can select all structural Elements columns beams floors in the categories section and Walls in category section you can use advance selection to have more selection features and click join. The add-on will join each wall with the intersected Structural Elements.) 

we can select an element of the same categories Ex Wall with Wall / Floor with Floor .....

Do operations according to the following criteria:

• Make Join operation only on based on Rule-based Filters in the project
• Make Join operation only on the elements in the level selected
• Make Join operation only on the structural walls or non-structural walls elements
• Make Join operation only on In-Place elements
• Make Join operation on Touched or Imbricate geometries
