A simple example of a family map is a solid panel as shown below:
...
Family Name is shown in the Revit Properties window when the part is selected in the model.
Type Name is shown in the Type Properties window accessed by clicking on Edit Type in the Revit Properties window. This textbox can be left blank to accept “All Types.”
Family Type is either Precast or Reinforcement.
Category depends on the selected Family Type. If Precast is selected then the category will be a type of precast element such as Solid Panel, Insulated Panel, Column, IT Beam, Spandrel, and so on. If the Family Type is Reinforcement then the category can be Strand, Rebar, Stirrup-Spiral, Stirrup-Tie or Mesh.
Design Type is only available if the Family Type is Precast. The available options are Beam, Column or Wall.
...
Property is the value that Sync needs for the family map.
Parameter/Value is either the name of the property in the family or type that corresponds to the property or is the constant value for that property.Is Constant is checked if there is a constant value in the Parameter/Value column and is not checked if it is a parameter of the family
Type describes the type of the property. It can be Parameter or Constant. Parameter means the property is found in the family instance or the family type. Constant means the value is a constant and doesn’t need to be found in the family instance or type.
All Precast family maps contain at least four common properties:
...
The Solid Panel example also shows how to use Parameter and Value types. For that family the thickness of the panel is a constant value of 8” so a value of 8” is input in the Value column and the IsConstant box is checked Type is set to Constant, so that Sync will not search the family for a thickness property and just set thickness to the constant value. The width value is a property of the family and corresponds to the Parameter of DIM_LENGTH in the family and instance so the IsConstant box is not checked so Type is set to Instance so that Sync will pull the width value from the appropriate parameter in the family instance.
