Join Elements

Used to join two or more existing linear building elements, having coinciding end points; include walls, beams, duct, pipe segments to create a single element. The new element is created on a line that extends from the first element selected. Properties from the first element (identified during the joining sequence) are propagated to the second element (that is identified).

Important: The joined segments must be collinear. Their end points, where they are to be joined, must be coincident (occupying the same point in space). Only pairs that satisfy these requirements can be joined with the Join Elements tool.
Important: In the case of Structural members containing analytical members, the analytical member end points, where they are to be joined, must also be coincident.
Note: The Join Elements tool does not include tool settings. Refer to the command prompts when interacting with the tool.
