Unsupported Datum Reference Attributes
This message indicates that one or more of the datum reference strings includes unsupported attributes. This version of GD&T Advisor does not support DOF constraint modifiers for defining a customized datum reference frame.
You may leave the DOF constraint modifiers, but you should be aware of the following:
• GD&T Advisor does not check DOF constraint modifiers, so it cannot evaluate whether they have been applied to the datum features correctly and cannot evaluate how they may affect the constraint state of the affected features.
• If you edit the GD&T Advisor feature, unsupported attributes will be removed from the feature control frame.
