The model DTL file has a setting called "default_tolerance_mode". This setting controls the tolerance mode for both created annotation dimensions and the feature dimensions (the sketch dims, driving dims). For MBD it would be helpful to be able to control the tolerance mode independently for feature dimensions and annotation dimensions. Maybe a new DTL option called "default_annotation_tolerance_mode" that would apply to created annotations while the existing setting "default_tolerance_mode" would then apply to just feature dimensions.
The reason behind this is that for MBD created annotations are used almost exclusively and it would be desirable to have the created annotations have a tolerance by default while the feature dimension would not have a tolerance.
