3 Drawing and Digital Shape Model (DSM) in combination

In order to provide a complete definition of a part, a drawing and a digital shape model (DSM) are often used in
combination as primary documents. In such cases, the following fundamental requirements and other provisions
apply:
When dimensions and other properties are indicated on the drawing, these apply.
Dimensions displayed on the drawing are considered resolved dimensions. These must not be in conflict
with dimensions obtained from the model; however they shall be rounded to the number of decimal places
required for the design. See section 4.5.2.2.
Dimensions, e.g. theoretically exact dimensions, which are not displayed on the drawing, shall be
obtained by querying the model.
Values obtained from the model for any feature(s) where no tolerance or datum target specification has
been stated, shall be considered auxiliary dimensions.
The part may be represented on a drawing using one or more orthographic or axonometric views and sections.
Figure 1 shows a digital shape model without any annotation. A drawing shall be used along with it to provide
geometric and other requirements.
Printed copies are uncontrolled. Print date: 2007-12-13
