Attach the families

[anis.123]

I have 3 families, Deck slab, girder and Asphalt wearing course. The problem is that I want to attach these families such that if move or tilt the girder, all the families attached will also move or tilt along with it!!! Is there any way to do this !!! THANKS

If the families have a common reference plane, for example, top of girder, then you can align and lock them in project.

Why families, why not using structural floor and structural frame?

How can I lock them in project. All these 3 families have same level of reference - The pile cap. But how can I align and lock then in project

Set up the required reference plane in the Project. Use the Align tool to align the element to the reference plane and then lock it.
