4.2.140 Default_edge_round

A Default_edge_round is the definition of an edge round that shall be applied to any non-tangent continuous, convex edge of a shape where no other edge round or chamfer is specified. For a given context only one of Default_edge_round and Default_chamfer shall be specified at a time. A Default_edge_round 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 edge rounds is often omitted to save on time and model size.

The data associated with a Default_edge_round are the following:

4.2.140.1 description

The description specifies additional information about the Default_edge_round.

See default_edge_round to multi_language_string for the application assertion.

The description need not be specified for a particular Default_edge_round.

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

4.2.140.2 radius_value

The radius_value specifies the amount of curvature for a convex transition between two faces.

See default_edge_round to feature_parameter for the application assertion.
