If you edit a family that exists in your project and then load it back into
the project, the instance parameter values do not change from their existing
states in the project. When you are loading a family into a project and a
type parameter value in the family is different from those in the project,
a dialog box that warns you that the object already exists in the project
gives you the option to overwrite the family and its parameter values, which
will change any type parameters to the value as it exists in the family. All
instance parameter values will remain unchanged even if they are different
in the family.
As mentioned earlier, Yes/No parameters are great for controlling the
visibility of objects. After creating a Yes/No parameter, you can select the
desired object and set its Visibility parameter to the value of the Yes/No
parameter by using the small button at the far right of the Visibility
parametervalueinthePropertiespalette.
