CAD properties can be mapped to aPriori User Defined Attributes (UDAs). In the mapping file, these targets are defined as type "uda". As mentioned earlier, a CAD property can be mapped to a UDA, a production input ("system"), or to both.
Mapping UDAs that have default values
The mapping behavior for UDAs is basically the same as that for system-defined production inputs. However, if you have defined a default value for an aPriori UDA through the System Administration UDA dialog, that UDA will NEVER use a CAD Property value, even if it is correctly mapped. (This behavior may change in a future release.)
