12、 reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for
13、 which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on a
14、ll matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are
15、 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an In
16、ternational Standard (“state of the art“, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer
17、valid or useful. Attention is drawn to the possibility that some of the elements of this part of ISO/TR 13567 may be the subject of patent rights.

21、e fields, together with default field sizes and, in certain cases default codes, are detailed in ISO 13567-2. However, the coding of certain layer name fields is not included in the standard, as it is recognized that for these specific fields the coding is more appropriately determined at national o
22、r project level. ?ISO 13567-2 also requires that the order of fields in a layer name, and the number of characters for each field, should be maintained as noted in the standard, unless an alternative is specifically agreed by the project parties. Furthermore, it is required that the layer name stand
23、ard used is documented in a way that assures future retrieval of the layer structured information. ?This Technical Report provides detailed guidelines on how to document project specific layer structure and coding conforming to the requirements of ISO 13567-1 and ISO 13567-2. It also addresses the c
24、ommonly employed practice of incorporating constant elements of the layer name coding in the name of the file containing these layers.

27、 of the requirements of ISO 13567-1 and ISO 13567-2 and in particular as a guide to documenting and communicating specific CAD layer name structure and coding complying with those standards. ISO 13567 consists of three parts dealing with organization and naming of layers for CAD. ISO 13567-1 has gen
28、eral application, while ISO 13567-2 details the concepts, formats, and codes to be used for naming of CAD layers employed in the preparation of construction documentation. This Technical Report deals with the mechanics of documenting and communicating the specific structure and coding used in an app
29、lication of the layer name standard. 2Conformance to ISO 13567-1 and ISO 13567-2 ISO 13567-1 and ISO 13567-2 provide a detailed definition of structure and coding of the CAD layer names to be used on construction projects. The standard specifies a default structure and coding rules, but also allow f
30、or national and project specific implementations, which vary from the default. The following sections describe the differences between a layer naming system using the ISO 13567-1 and ISO 13567-2 default structure and coding (Default conformance) and a system which uses a project specific application
31、 of the standard (Conceptual conformance). 2.1Default conformance Default conformanceto ISO 13567-2 requires that all of the mandatory and optional codes defined in the standard be used in the order specified, with the default field sizes, and using those codes set out in the standard. The optional
32、fields need only be included up to the last used field with the underline character “_” used to fill unused internal layer name fields. Default conformanceprovides a layer name convention which, in the absence of an agreed project alternative, is assumed to be the format used on the project. An exam
33、ple of a layer name structure which satisfies the requirements of the standard usingDefault conformance, is shown in Figure 1.

35、e order listed in the standard, it will usually lead to sparse and inelegant layer names which would not have strong user support and it is therefore not expected to be used in normal working situations. However, aDefault conformancedefinition is needed to provide a “neutral” framework to which alte
36、rnative layer definitions can be converted when data is to be archived, and to provide a base definition which can be used in the absence of either a national standard or an agreed layer naming convention for a project. In other words,Default conformanceis a common starting point for defining nation
37、al or project standards. 2.2Conceptual conformance 2.2.1Layer name fields Conceptual conformanceto ISO 13567-2 is designed to allow national standards bodies (or projects where agreement is reached between the parties) to implement layer naming conventions which satisfy the requirements of the stand
38、ard while using alternative and more convenient layer naming structures and codes. Conceptual conformancerequires that the mandatory fields be always used, but allows for varying the number of optional fields and the order of these fields, and for varying the size of all fields from the default fiel
39、d sizes. However, the conceptual content of each field cannot be varied from the definitions in ISO 13567-2. An example of the syntax of a layer name using a structure, which satisfies the requirements of the standard using Conceptual conformance,is shown in Figure 2. Figure 2 Example of “Conceptual

41、-3:1999(E) ISO 1999 All rights reserved3 2.2.2Coding for file names and layer names In a construction industry design project CAD files are the basic package containing graphic information, whereas layers are the principle means of categorising the graphic data within the CAD files. Layer names conf
42、orming to the requirements of ISO 13567-2 provide a comprehensive mechanism for categorizing data within CAD files. However, by using file names in conjunction with layer names it is possible to reduce duplication of coding information and to facilitate ordered use of reference files on a project. T
43、ypically the file name may include one or more codes for particular layer name fields where these codes would be constant for all layers contained in the CAD file. In such a situation the fields in question are omitted from the layer name, and the file name and layer name are read together to fully
44、describe the contents of a particular layer in the file. Using a combined file name and layer name convention is clearly in conformance with the requirements of ISO 13567-2, provided the coded information can be translated into aDefault Conformancelayer name structure, if required. This Technical Re
45、port includes an example (in annex A) of definition and communication of codes, which are to be coded in the file name instead of the layer name and thus constant for all layers in a CAD file. 3Structure and coding of CAD layer names 3.1Minimum documentation requirements To adequately document the s
46、tructure and coding of a naming system for CAD layers (or combined naming system for CAD files and layers) as used on a project it is necessary to provide the following: 3.1.1A link to ISO 13567-2 subclause number for each CAD layer name field The concept, format and code for each of the mandatory l
47、ayer name fields are specified in clause 6 of ISO 13567-2. Similarly, the details for each of the optional layer name fields are specified in clause 7 of that standard. The documentation of the project specific CAD layer naming system must identify those fields used in the layer name by direct refer
48、ence of the given field name to the relevant ISO 13567-2 subclause. 3.1.2The size of the layer name fields ISO 13567-2 details default sizes for each layer name field. However, since the order and size of each field may be varied from these defaults, it is necessary to clearly document the size used for each field to ensure accurate interpretation of each field value. The documentation of the project specific CAD layer naming system must identify the size in character positions of each field
