The steps used to create diameter datum targets has changed in Release 2001. In Release 2000i2, the user was prompted to select on a diameter dimension for use in the datum target. The recommended procedure was to create a hatched cosmetic feature with the appropriate diameter prior to creating the datum target. When the diameter of the cosmetic feature was selected, the leader of the target would be attached to the cosmetic feature.
In Release 2001, there is no need to create the cosmetic feature in the model. When creating the datum target, the user is prompted to enter in a diameter value. The hatched area is automatically created with the datum target leader attached to it but the diameter of the hatched area is not the entered value.

Resolution
-----------------
This issue is resolved in Release 2001, version 2002030 and later. The functionality is similiar to Release 2000i2. The drawing setup file option "gtol_datum_area_target_sym" has been removed. During creation of the datum target, the options #Simple, #Diameter, #Box, and #Line allow the user to select which type of target will be created. Instead of manually entering a dimension for the target area, select a dimension on screen.
