Required Annotation Properties Have Been Changed
GD&T Advisor automatically creates native annotations on the design model. When you make a change to the properties of one of those annotations and then update the GD&T Advisor model, one of the following things will happen:
The GD&T Advisor model data is updated to reflect the change, such as a change to:
The tolerance mode, value, or precision of a dimension
The value of a geometric tolerance
The state of certain optional modifiers
The annotation property in the CAD model reverts to its original state, as defined in GD&T Advisor, in regards to the change in:
The diameter symbol applied to a geometric tolerance
The error message—Required annotation properties have been changed—is displayed, in regards to the change in:
The selected geometric characteristic symbol for a geometric tolerance
The material condition modifier applied to a geometric tolerance
A datum reference
The material condition modifier applied to a datum reference
The state of certain optional modifiers
An information message—User-specified annotation properties ignored—is displayed and the change is ignored, such as a change to:
'Per Unit Tolerance' specified
The state of certain optional modifiers
The change has no effect on the GD&T Advisor model and is ignored, such as a change to:
Dimension or tolerance name
Dimension display properties
This information message indicates that there has been a change to an aspect of the annotation properties that is not supported by GD&T Advisor and cannot be automatically validated. Thus, the change may cause problems with the part definition.
To reset the annotation to its expected properties:
1. Right-click on the feature in the Feature Tree and select Edit... from the context menu.
2. Specify the geometric tolerances in the dashboard as desired.
3. Click the Accept button in the dashboard.
