Many projects require the offsetting of structural framing members in the horizontal direction and Revit Structure provides only one tool to enable the Horizontal offset of a structural frame. This is called lateral justification and is often quite limiting as it only offsets the member about the analytical line and does not allow full control.
You can try this by selecting a universal beam and choosing lateral justification and setting Centre, Side 1 and Side 2 and see the results. Make sure that you have the analytical model switched on so you can see the physical and analytical positions.
It is possible to create your own parameter to control the horizontal offset of the physical framing member whilst keeping the analytical model unchanged. Of course, you can edit the analytical model if necessary.
To begin, select your universal beam and choose edit family from the right click menu. This will open the family editor. You will see the 3D model of your beam. You are actually seeing two 3D sweeps, one model for the medium level of detail without a root fillet radius and the fine model which contains the root fillet.
Select both models as shown below and then choose the associate family parameter command.
In the associate family parameter dialog box, choose Add parameter. Add a parameter called Horizontal Offset, make it an instance parameter and group this under Constraints as shown below.
Click OK to both dialog boxes and then load this into your current project. Select a universal beam and you will now be able to control the horizontal offset as shown below.
Note that you will also have to edit the symbolic lines (Hidden detail) to make the beam look correct in a plan view. I will create a video at a later point to show this process.
