ISO 10303-214:2010(E)
A Layer is a general structure for the collection of geometric and annotation elements. Layers shall not be nested, i.e., a layer shall not be an element of another layer.
EXAMPLE The design of a mechanical part as a B_rep_model is performed in several steps:
The data associated with a Layer are the following:
The description specifies additional information about the Layer.
See layer to multi_language_string for the application assertion.
The description need not be specified for a particular Layer.
If present, there shall be exactly one object that defines the description for a Layer.
The element specifies a piece of product data that is collected by a Layer.
NOTE Although not explicitly modelled in the ARM, the element can be on various levels of granularity, e.g., a whole B-rep-model or a single Cartesian point.
See layer to detailed_element for the application assertion.
The id specifies the identifier of the Layer.
