DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Layer Naming Convention This document as provided as is and may be used as a basis for companies or projects wishing to implement a layer standard in accordance with BS1192:2007 and Uniclass. The Layer documentation provided is an implementation of the layer standard as defined within BS1192:2007 and incorporates CPIC’s Uniclass classification table 1.4 published January 2011. 1 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Background BIMuk comprises conventions, documentation and guidance on best practise for incorporating BIM software and procedures into the AEC Industries within the United Kingdom. BIMuk brings together many UK standards already used within the Architectural, Engineering and Construction Industries and provides conventions for how the standards can be implemented for any company or project. Contributors to these standards include authors of relevant British Standards, CPIC guidance documents plus lead individuals from many companies in the forefront of BIM technologies in the UK. This document is based upon the layering standard as defined within BS1192:2007, which is the prevailing document relating to Layer Standards. 2 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Scope This document provides guidance on the implementation of the BS1192:2007 Layer standard using the Uniclass Classification system. Since the launch of the BS1192:2007 Standard there have been further developments in the relevant British standards including the release of BS8541-2:2011.The requirements of this standard has led to the development of additional presentation codes for layers that are available for use, if required. BS1192:2007 mandates the use of Uniclass as the classification system to be used within Layer names. The original implementation of the Element fields within Uniclass meant that often the use of concatenated Uniclass codes was required in order to classify specific elements. CPIC have therefore carried out additional work within this area and have recently published version 1.4 of Uniclass in January 2012 for the CPIx Layer Generator. This unifies tables G (Elements for Building) and H (Elements for Civil) into one combined table G to enable the classification of elements across both Building and Civil, whilst also removing the need for concatenated codes. There has also been work on Table Z which provides a table for CAD specific classifications. This document provides guidance on how to implement a layering convention to comply with the requirements of BS1192:2007 using the following:• • • Uniclass Classification version 1.4. Enhance Presentation codes for 3D modelling Agreed Alias Convention for Uniclass version 1.4 It also provides further information regarding how the relevant layer fields defined within BS1192:2007 shall be implemented whilst For a more detailed description of the standard please refer to either BS1192:2007 itself or the supporting documentation produced by the BSI and links can be found on the BSI web site. Uniclass is a classification system owned and developed by CPIC (http://www.cpic.org.uk/) and the data presented in this document is based upon the Uniclass 1.4 version released in January 2012. This is available from the CPIC web site and used within the CPIx Layer Generator Tools. Please check the CPIC website for the latest updates to the Uniclass standard. Special Characters To ensure compatibility and interoperability between CAD software the use of special characters and spaces MUST NOT be used in any Layer naming conventions. Therefore the following best practise should be followed:Only the letters (A to Z), hyphen (-), underscore (_) and numbers (0-9) shall be used in the naming CAD Layers . • Spaces MUST NOT be used. The following characters MUST NOT be used in any circumstances:• ,.◦ ! “ £ $ % ^ & * ( ) { }[ ] + = < > ? | \ / @ ’ ~ #¬ ` ‘ 3 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Implementing the BS1192:2007 Layer Standard BS1192:2007 allows only for the following fields to be included within any Layer Name:Field Role Name Example A Architect Classification / Element Presentation - G23 Stairs (Uniclass) - M2 Model Graphics Alias _ Stair Text There are various methods of implementing the Layer standard within BS1192 which has led to inconsistences. Therefore to aid with a common approach CPIC have provided a tool on their Web site to enable a common approach. This tool can be found at http://cpionline.cpic.org.uk/FrmCPILayerGenerator.aspx By following the contents of this document you should be able to create the same layer standards using a manual process. Layer Fields The description below provides information relating to each of the fields in BS1192. Data options for each of the fields is provided later within this documentation. Field 1: Role (1 Char) ‘The Discipline who is the owner of the information’ This is a single Character code representing the role of the creator of the data produced. BS1192:2007 provides a list of the disciplines which has been replicated later in this document. A Hyphen (-) is used as a separator between the Field 1 Role and Field 2 Classification. Field 2: Classification / Element (Variable) BS1192:2007 mandates the use of Uniclass as the classification system to be used within Layer names. A list of the Uniclass Tables F - Spaces, Table G – Elements for Building and Civil and Table Z - Computer Aided Design are provide later in this document. A Hyphen (-) is used as a separator between the Field 2 Classification and Field 3 Presentation. Field 3: Presentation Codes (2 Char) BS1192 allows for a definition of the graphics to be used to represent an object in either a single or two letter codes. Where graphic representations are to be kept simple then the single codes as defined within BS1192:2007 should be used. To aid with BIM implementation, where further graphics control is required, a two character code should be adopted Two Character codes definitions are provided later in this document and include for additional presentation requirements as included with BS8541-2:2011. An Underscore (_) is used as a separator between the Field 3 Presentation and Field 3 Alias. Field 4: Alias Description code to assist Layer Identification The purpose of the Alias fields is to assist the identification of the building elements defined by the classification system. To ensure the consistent use of the Alias field CPIC have provided a standard list of Aliases to be used with each of the Uniclass classifications included with Uniclass version 1.4. These are included with each table code. Underscores are used to replace spaces within the Alias and any plurals are removed. 4 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Layer Name Examples The following Wall examples demonstrate how layers could be used in Practice. Where possible the minimum amount of layers should be used to aid the correct viewing, presentation and collation of data. Therefore just the Simple Layer codes should be used in most circumstances. Where there are complex drawings or where presentation requirement further graphic refinement, then the complex layer codes should be used. Simple Layer Codes Layer Name Description of Layer make up A-G25-M_Wall A-G25-A_Wall Architect Wall for all model views Architect Wall Annotation (Tags etc.,,,) Complex Layer Codes Layer Name Description of Layer make up A-G25-M_Wall A-G25_MC_Wall A-G25_MH_Wall A-G25-MV_Wall Architect Wall for Model Graphics (any view) Architect Wall Model Cut plane (Section / Details) Architect Wall for Hidden lines beyond cutting plane (BS8541-2:2011) Architect Wall Visible items Behind / above the cut plane (BS8541-2:2011) Architect Wall Annotation (Tags etc.,,,) A-G25-A_Wall Typical Layer use examples Some typical layer use examples are provided to demonstrate the application of the convention: Layer Name Description of Layer make up A-G321-M_Window A-G321-A_Window A-Z78-M_Mass A-F2-A-Room A-Z221-T_Text Architect Window Model Graphics (Any view) Architect Window Annotation (Tags etc.) Architect Massing Objects Architect Room Annotation (Tags etc.) Architect General Text M-G52-M_HVAC M-G52-A_HVAC Mechanical Engineer HVAC Model Graphics (any view) Mechanical Engineer HVAC Annotation (Tags etc.) S-Z81-M_Con S-G262-M_Column Structural Engineer Construction Lines Structural Engineer Column Model Graphics E-G55-M_COMM E-G55-A_COMM Electrical Engineer Communications Model Graphics Electrical Engineer Communications Annotation (Tags etc.) 5 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Field 1: Role The Role field defines the discipline for the owner of the information to be produced within CAD. There are specific implementation differences between fields such as 'Role' in the UK and 'Discipline' in the USA; Within BS1192:2007 the 'Role' field signifies the Author or Owner of the information. Therefore when an Architect draws a column the layer 'Role' field must be designated with the letter A for Architect. In the USA the Layer Field refers to the 'Discipline' having responsibility for the object. So in the USA the Architect would draw a column and the 'Discipline' field would be designated S, passing the responsibility to the Structural Engineer. In the UK each discipline only draws on the layers where the Role Field designates their specific discipline. Therefore anything an Architect draws must be on a Layers commencing with the letter A. The following table is taken from BS1192: CODE Discipline A B C D E F G H I K L M P Q S T W X Y Z Architects Building Surveyors Civil Engineers Drainage Sewage and Road Engineers Electrical Engineers Facilities Managers GIS Engineers & Land Surveyors Heating & Ventilation Engineers Interior Designers Client Landscape Architects Mechanical Engineers Public Health Engineers Quantity Surveyors Structural Engineers Town & Country Planners Contractors Sub-Contractors Specialist Designers General (Non disciplinary) 6 DRAFT 1.0 January 2012 Layer Convention Http://www.BIMuk.org.uk Field 2: Classification / Elements A list of the Uniclass codes for version 1.4 correct as of January 2012 is provided here.
