• All angular values shall be queried from the model. Exceptions to this are model coordinate system(s) and
planes and axes in datum systems.
• Annotation in any given annotation plane shall not overlap other annotation in the same annotation plane
when the model is viewed perpendicular to the annotation plane.
• Annotation text within any given annotation plane shall not be placed over the DSM when the model is
viewed perpendicular to the annotation plane.
• All annotation shall be specified in one or more annotation planes. Figure 4 shows the principle of using
annotation planes. When CAD software does not support maintenance of annotation-plane orientation
relative to the model, the model-only method shall not be used.
a) Perpendicular annotation plane
b) Coincident annotation plane

• The associated entities, annotations, and attributes shall be in agreement.
• Resolved dimensions created from queried model values are considered the same as dimensions
displayed on a model.
• Display of centrelines or centre planes for features of size is optional.
• To ensure that the annotation is readable
− the text, for example, could be upside down or
backwards following rotation of the model
− one of the following techniques shall be used:
o ensuring that the reading direction is updated after rotation of a model
o inclusion of means of determining the correct reading direction in each annotation
plane applied to a model
o when using saved views, ensuring that the model is orientated in the intended view direction
− for
example, by including a means of determining the correct reading direction in the view.
• Dimensions and tolerances to internal features may be shown without the use of a section. See figure 5.
