This standard was last reviewed and confirmed in 2022. Therefore this version remains current.


ISO/TS 10303-1788:2018-11 specifies the application module for Explicit constraints.

The following are within the scope of ISO/TS 10303-1788:2018-11:

  • specification of constraint relationships between constituent elements in a model, expressing the intention that these relationships should be preserved on modification of the model following an ISO 10303 transfer;
  • free-form constraints enabling the capture and transmission of explicitly defined mathematical relationships between quantities in a model;
  • defined constraints, for the representation of relationships defined descriptively, with implied mathematical semantics;
  • specification of sets of constraints that are required to hold simultaneously in the model;
  • items within the scope of application module Expression, ISO/CD-TS 10303-1342;
  • items within the scope of application module Foundation representation, ISO/TS 10303-1006;
  • items within the scope of application module Parameterization and variational representation, ISO/TS 10303-1790.
