This message means that the model contains annotation elements that were not created as a geometric Tolerance Feature such as a general dimension or hole note.
Inventor supports both Tolerance Feature annotations (GD&T) and general 3D annotations in a model. The Tolerance Advisor uses the Tolerance Feature annotations and the General Profile Note to analyze the model tolerance information. Because general annotations can result in an over-constrained part or incorrect constraint state, they are reported in the advisor. Delete the general annotations to remove this message.
If you want to use both, we suggest that you add general 3D annotations after you add all the required tolerance annotations and are satisfied with the Tolerance Advisor messages.
