This clause specifies the information requirements for the
Compound shape representation
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.
The following EXPRESS specification begins the
Compound_shape_representation_arm
schema and identifies the necessary external references.

This subclause specifies the ARM entity for this
module. The ARM entity is an atomic element that
embodies a unique application concept and contains attributes
specifying the data elements of the entity. The ARM
entity and definition is specified below.
A Compound_shape_representation is a type of
Geometric_model.
A Compound_shape_representation is a geometry model where elements of different dimensionality,
such as wireframe models or surface models, are topologically connected.
The topology of a Compound_shape_representation may be non-manifold.
NOTE
A Compound_shape_representation may include non-manifold surface models as well as
topologically bounded three-dimensional wireframe models.
