As in most aspects of CAD drawing, the current usage of colour and linetype in CAD drawings is very much related to the manual drafting methods. Manual drawings are almost entirely created in monochrome with different line widths while CAD drawings make use of different colours to denote different line widths. With the availability of 256 or more colours in CAD programs and 2 dozen or more linetypes, and the non-uniformity of different CAD software in handling colours and linetypes, CAD drawings are complicated and hence non-productive. This code aims to simplify the use of colour and linetype in the process of creating CAD drawings. This code also lists the additional layers to cater to the requirements of M & E users. Several of the important layer names which had not been defined in CP 83 : Part 1 surfaced during the course of developing this code and are now covered under Annex C of this code. This code was prepared with reference to following Singapore Standards: 1. CP 6 : 1978 Code of practice for building drawings 2. CP 83 : - Code of practice for computer-aided design (CAD) Part 1 : 2000 Organisation and naming of CAD layers NOTE 1. Singapore Standards are subject to periodic review to keep abreast of technological changes and new technical developments. The revisions of Singapore Standards are announced through the issue of either amendment slips or revised editions. 2. Compliance with a Singapore Standard does not exempt users from legal obligations. CP 83 : Part 5 : 2001 7 Code of practice for construction computer-aided design (CAD) – Part 5 : Colour and linetype 1 Scope This code is to establish the general principles and formats for usage of colour and linetype for construction computer-aided design (CAD) files.
