Visible Parameter and Associate Family Parameter

When we work with Forms, Symbolic and Model lines and nested families they each have a parameter called Visible and we can use Associate Family Parameter to control their visibility.

If you decide to remove this relationship Revit applies the current state of the parameter that was controlling it to the Visible parameter. If it was checked (visible on) then removing the parameter relationship leaves it checked. If the reverse is true (visible off) then the opposite happens.

It's subtle and can cause a few minutes of confusion when you reload a family and find it isn't visible.
