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.
