4.2.139 Default_draft_angle

A Default_draft_angle is the definition of an angle that is applied to each planar face of the part that is oriented in this draft direction.

NOTE For parts manufactured by casting, the draft angle is necessary to facilitate the extraction of the part out of the form after the casting.

NOTE 2 There may be various draft directions depending on the actual shape of the part. The Default_draft_angle is, therefore, not necessarily meant to enable a system to create a resulting shape out of the application of the angle; in most cases this is additional information that has to be interpreted by human beings.

The data associated with a Default_draft_angle are the following:

4.2.139.1 description

The description specifies additional information about the Default_draft_angle.

See default_draft_angle to multi_language_string for the application assertion.

The description need not be specified for a particular Default_draft_angle.

If present, there shall be exactly one object that defines the description for a Default_draft_angle.

4.2.139.2 draft_angle_value

The draft_angle_value specifies the value of the Default_draft_angle.

See default_draft_angle to feature_parameter for the application assertion.
