4.2.138 Default_chamfer

A Default_chamfer is the definition of a chamfer that shall be applied to each non-tangent continuous, convex edge of a shape where no other chamfer or edge round is specified. For a given context only one of Default_chamfer and Default_edge_round shall be specified at a time. A Default_chamfer is applicable only to edges that do not change from convex to concave.

EXAMPLE During the creation of a 3D CAD model, the explicit modelling of chamfers is often omitted to save on time and model size.

The data associated with a Default_chamfer are the following:

4.2.138.1 description

The description specifies additional information about the Default_chamfer.

See default_chamfer to multi_language_string for the application assertion.

The description need not be specified for a particular Default_chamfer.

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

4.2.138.2 offset_value

The offset_value specifies the width of the chamfer with respect to the two faces where it is applied to.

See default_chamfer to feature_parameter for the application assertion.
