•
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.
