Application module: Curve appearance | ISO/TS 10303-1003:2019(E) © ISO |
This clause specifies the information requirements for the Curve appearance application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information requirements is given in Annex C.
NOTE 2 The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.
This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the Curve_appearance_arm schema and identifies the necessary external references.
