Use Global Parameters to Control Visibility
In this example, we have two furniture families (dining table and chairs). Ideally, you would want to control the visibility of these families at the same time. Both families should have visibility parameters embedded inside of them. Click the small rectangle to add a global parameter.
Create a Global Parameter to control Furniture Visibility
You can now control the visibility of the chairs in the entire project by going to the Global Parameters menu and checking/unchecking the box.
In this example, we’ve assigned the global parameter to the chairs, but not to the table.
