ISO 10303-214:2010(E)
A Design_constraint is a requirement that has to be considered in the design process of a Complex_product. This constraint may be geometry based.
EXAMPLE Ergonomic information like 'hip point' or 'forward driver vision' as well as 'door opening control lines', 'shipping critical dimensions', or 'stone throw zone' are examples for Design_constraint.
EXAMPLE The diameter of a standard soft drink can is a constraint for designing the hole of a cup holder in a car.
Each Design_constraint may be a Design_constraint_version.
The data associated with a Design_constraint are the following:
The constraint_id specifies the identifier of the Design_constraint.
The description specifies additional information about the Design_constraint.
See design_constraint to multi_language_string for the application assertion.
The description need not be specified for a particular Design_constraint.
If present, there shall be exactly one object that defines the description for a Design_constraint.
The is_valid_for specifies the set of Product_class objects that are affected by the Design_constraint.
See design_constraint to product_class for the application assertion.
The name specifies the word or group of words by which the Design_constraint is referred to.
See design_constraint to multi_language_string for the application assertion.
The name need not be specified for a particular Design_constraint.
If present, there shall be exactly one object that defines the name for a Design_constraint.
