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 parameter. It can be Instance, Constant, or Type. Instance means the parameter is found in the family instance. Type means the parameter is found in 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.
