IFCPRESENTATIONDIMENSIONINGRESOURCE
The data model consists of the following:
The schema IfcPresentationDimensioningResource defines the
resources used for geometric representations and presentations of presentation
callouts used for dimensioning. The primary application of this resource is for
presenting the annotation occurrences of linear, radius, diameter and angular
dimensions.
NOTE: The definitions of this
resource of the IFC model have been taken from the International Standard
10303: "Industrial automation systems and integration - Product data
representation and exchange", Part 202 "Application protocol: Associative
draughting". The reference is ISO/IS 10303-202:1996.
The IfcPresentationDimensioningResource contains all those
definitions from ISO/IS 10303-202:1996, which are not already defined within
the Integrated Resources of the International Standard 10303, namely in part 42
"Integrated generic resources: Geometric and topological representations", and
part 46 "Integrated generic resources: Visual presentation". It contains such
definitions that are used in ISO/IS 10303-202:1996, but are originally defined
in part 101 "Integrated application resources: Draughting".
The definitions taken from ISO/IS 10303-202:1996 have undergone a
adaptation process, characterized by:
- adaptation of the IFC naming convention (inner majuscules and Ifc
prefix)
- adaptation of the STEP entities, where multiple inheritance or
non-exclusive inheritance (i.e. AND or ANDOR subtype constraints) are used
- selection of a subset of the IR, using subtype and select
pruning
- dimensionality of geometric representation items defined at each item
(not through the representation context)
- omission of the name attribute at the representation item
The definitions taken from ISO/IS 10303-202:1996 are explicitly
excluded from the copyright of the International Alliance of
Interoperability.
NOTE: For more information on
the definitions as defined in the formal ISO standard please refer to: ISO/IS
10303-202:1996, Industrial Automation Systems and Integration: Product Data
Representation and Exchange - Part 202: Application protocol: Associative
draughting. The formal standard can be obtained through the local publishers of
standards in each individual country.
