5.1.2 Sheet sizes

The standard sizes of ICE drawing sheets are in accordance with ISO 5457, namely A series, as presented below. The basic size in this series is the A0 size (1189 x 841mm).

Drawing Sheet Size

Size [mm]

ICE Form Code Drawing

A0 1189 x 841 Form Code Dwg.A0





The use of A0 size is to be avoided wherever possible unless it is a specific contract requirement. The preferred size for drawings is A1. A3 and A4 drawings are preferably to be used for drawing packages (e.g. booklets of drawings). A package may consist of a cover sheet, an index sheet (or sheets) and the drawings which make up the package. All drawings within a package shall have the same document number but be identified by unique and consecutive sheet numbers. Drawings are to be produced to the most appropriate scale in order to meet the requirements for the respective type of drawing (concept, basic or detail). This is intended to maintain clarity once all dimensions, symbols, item numbers and miscellaneous details have been included. The originator is responsible for the accuracy and clarity of drawings. It will be for the originator to decide upon the appropriate number of sheets. References:

5.3 DRAWING PART LAYOUT

This area of a drawing sheet is designated solely for graphical representations such as plan views, elevations, sections, details, diagrams, schematics, etc. It is vitally important that views must always be laid out in a logical, consistent and easy-to-read manner in accordance with the following rules:

- the frame numbering (frame ruler) of one view is to align with the frame numbering of others; - section views are to be aligned and laid out such that they are in a logical numeric sequence; - datums (e.g. centrelines, baseline) are to align from one view to another; - details are to be identified and positioned in a logical alphanumeric sequence; - plan views of decks must be tiered one above the other in sequence with the lowermost deck

at the bottom of the drawing area and the uppermost deck at the top of the drawing area. Only under exceptional and agreed circumstances are these rules to be infringed. Further information regarding projection methods, scales, titles, dimensioning, referencing, etc. are given in instruction parts 5.3.1 to 5.3.9 of this document.

5.3.1 Creating a drawing in Model Space / Paper Space

Model Space is an environment in which all drawing components are drawn at a scale one to one, and millimetre is the preferred measurement unit. The drawings must be positioned versus the defined coordinate system. This will enable an accurate integration / superimposition between various drawings. Paper Space / Layout is an environment enabling the creation of sheet layouts for plotting purposes. Paper Space is not intended to be used for full scale drawings. A drawing may be created in one of two ways:

- Inside Model Space: views, cross-sections, details, dimensions, different types of blocks (revision clouds, item number, weld symbols, etc.) at a scale 1:1, and inside Paper Space: Administrative Part and viewports.

- Entirely within the Model Space when the previous method proves to be troublesome. In this case the main view is created at a scale of 1:1. All entities consisting of plan views, elevations, sections, details, text, dimensions, title block, border, etc are to be scaled to suit the intended drawing plot size.

Steps for producing a drawing:

- Creating a model. - Creating a Paper space Lay-out; - Creating Viewports; - Sizing / dimensioning and inserting symbols, item numbers and text.

Creating a model It is important that the model is created in a logical and orderly manner, so it will be clear to anyone who uses the drawing as an eXternal-Reference. When attaching reference files, the path to this file should only be named as No Path. Set Reference Type on Overlay:




2010, ICEPRONAV



Creating a Paper space Layout From Model space switch to Paper Space environment. Page Setup Manager will be selected, and then Paper Size will be set to A1, Plot Scale to 1:1 and Plot Area to Layout. The drawing border, title block and other administrative blocks are then superimposed. Creating Viewports As a standard, a layer is made with the name Viewport. Otherwise this layer should be created. The existing viewport must be produced at a desired scale (i.e. 1:50) and then be locked. The viewport will be sized and positioned upon the drawing area. Any other necessary viewport is to be created, scaled and sited as above. References:

5.3.2 Projection method

The method shown by Reference Arrows is mainly used for ship work rather than the First Angle Projection Method. The ICE projection method used is the European projection - first angle projection (ISO 5456-1).

If the use of European projection method is not suitable due the lack of space in the drawing format, then another possibility for representation of projections is by using Reference Arrows:

Principal view

Principal view




2010, ICEPRONAV



Projections A and B (view from A or view from B) can be placed below principal view in a single row. Sections parallel with A or B will be subject to the same treatment. Projections C and D (view from C or view from D) can be placed in the same row with the principal view in the right side. Sections parallel with C or D will be subject to the same treatment. Naming conventions for views are as follows:

profile view meaning projection looking from starboard to port; plan view on main deck - meaning looking vertically downwards on main deck; plan view on platform - meaning looking vertically downwards on platform; plan view on tank top - meaning looking vertically downwards on tank top; section view at frame, e.g. Fr.100 - meaning cross-section (at Fr 100) looking from aft to

forward. General projection method can be summarised as:

- Looking from aft to forward5; - Looking vertically downwards; - Looking from starboard to port;

In general, the principal view should be the most informative, being the most recognisable during manufacture or use.

References: - ISO 5456-1 - Technical Drawings. Projection methods.

5 By exception and only when necessary, section views looking from forward to aft may of necessity have to

be used for the sake of clarity. In these circumstances such views will be clearly identified as looking aft.




2010, ICEPRONAV



5.3.3 Scale method

Drawings shall be to scale, except for diagrams and sketches. The main scale is indicated in box position 5 of the title block. Deviating scales are mentioned below the title of the relevant views, sections or details. Whenever a drawing refers to a diagram or a sketch, NTS (not to scale) will be written in box position 5 of the title block. Standard scales (ISO 5455), to be used:

- giving actual dimensions of all features of the geometry; - giving information about any special manufacturing processes and materials required.

General rules for dimensioning (ISO 129):

- Company accepted standards and conventions must be followed; - Dimensions must be placed on drawings so that they may be easily read; - Drawings must include only the minimum number of dimensions required for accurate

manufacture; - A dimension is not to be stated more than once, unless it aids communication; - It should not be necessary for the operator manufacturing or assembling the

component to need to calculate any dimension(s). All dimensions are in metric units, unless otherwise indicated. Font name, sizes, width factor and colour used:

- Font name: Arial. - Dimension lines: 0.18 mm. - Font size for dimensions text: 2.5. - Width factor: 1. - Colour: text, lines, arrows - by layer (red). - Layer: _G Dimensioning.

5.4 CAD DRAWING SPECIFICS

Preparation of CAD drawings will entail specific procedures and the use of tailor-made provisions, such as reference files, layer arrangements, blocks, AutoCAD Auto lisp, Visual Basic programs and commands. Recording and filing of CAD drawings differs from those directly draughted by means of non-CAD methods such as hand-draughted/non CAD produced drawings. CAD drawings are to be prepared in such a way that they are compatible with, and easily converted to, the various other CAD systems that may be in use. References:

- Essential features of CAD drawings are given in the instruction 5.4.1 5.4.3 of this document.




2010, ICEPRONAV



5.4.1 Layer arrangements

Different items of a CAD drawing are drawn on layers. The layer classification is dependent on the type of drawing. The following types of drawing are set:

- General; - Structure construction - Arrangements; - Piping and ducting layouts and schematics P&ID etc. - Electrical layouts, cables, etc. - Fire and Safety

For the various drawing types, the layer classifications are as given in Appendix 2. Each type of drawing will be built onto one or more specific layers. Entities such as electric cable, hull, etc. can be used as background for other drawings. Attributes such as colour and line width, for all entities pertaining to the background will be set to grey (253) and, respectively 0.18 mm. References:

- None




2010, ICEPRONAV



5.4.2 Line types, line styles and colours

The following rules (ISO 128-20) are applicable for lines attributes - colour, width (line thickness) and style:

LINE STYLE TABLE

LINE STYLE ACAD Line Type

Name Line pattern

5.4.3 CAD blocks

Blocks (for AutoCAD) are displays of standard elements, such as symbols, equipment, outfitting and auxiliary structures. Blocks are discipline related and maintenance of the block library is consequently allocated to the appropriate departmental CAD coordinator, under global responsibility of the CAD coordinator, who is also responsible for the maintenance of the blocks for general use. The structure for organizing block libraries is as follows: O:\ICE Standards\PROJECT SYSTEMS\

- ICE Menu - Library

- Symbols; - Models;

- Lisp (CAD commands) - Menu (pull-down menus) - Template (different templates)

Notes:

1. For some projects, specific blocks are created; those blocks (not belonging to the blocks for a certain discipline or for a specific client) are stored in project libraries (and will be stored in the computer backup for that order).

2. In order to create a new block in the project library, the following steps are to be used: - the entities must be drawn in layer 0. The entities will be drawn with colour, line type

and line weight attributes set BY LAYER. If necessary, these characteristics will be changed according to drawing standards.

- upon block completion, it will be saved by using WBLOCK command, into the folder corresponding with block destination or will be sent to CAD coordinator to do this operation.
