1.0 SCOPE
This document is a general guide for all AutoCAD users. It is designedto allow the creation of drawings that are consistent in quality andformat.
All drawings shall be legible under the intended conditions of use.
It is the responsibility of the user to follow these guidelines. Thisdocument should be used unless a specific project document dictatesotherwise.
2.0 DRAWING AND CAD REFERENCE DRAWINGS
Drawing numbers and CAD reference numbers shall be in accordancewith the SembCorp Simon-Carves (SSC) coding Manual. This can befound on the SSC Intranet, under Company Management System /Standards / Engineering / Company Coding Manual (Section 19 P&L).
3.0 FILING OF CAD DRAWINGS
For consistency all AutoCAD drawings are to be saved in AutoCAD2000 Format.
All drawings shall be stored on the network, in the correct projectdirectory and in the relevant sub-directories.
Drawings MUST NOT be stored on local drives.
Any drawing that has a revision change will be regarded as issued.
If a drawing has been issued, a copy must be placed in the relevantrevision folder, which should be a sub-folder of the relevant projectfolder.
To ensure that only the latest version of any drawing is available formodification, revision folders will be made “read only”.
Modifications will then be completed to the file in the project folder.

4.0 DRAWING SHEET SIZES
The following table shows the recommended drawing sheet sizes fromBSEN 61082.
Designation Dimensions (mm)
A0 1189 x 841
A1 841 x 594
A2 594 x 420
A3 420 x 297
A4 297 x 210
An SSC drawing frame for each size will be used via the appropriatetemplate file and will not be modified unless agreed in advanced withCAD Development. Refer to Section 6 AutoCAD Drawing Standards.
Sheet sizes used should be selected taking into account:
• Legibility
• The composition and complexity of the design
• The possibility of using a smaller sheet, but with a greaternumber of sheets
• The requirements of Computer Aided Design andDocumentation
• The requirements of handling, copying, filing and otherdocumentation processes.

5.0 DRAWING TEMPLATE FILES (.DWT)
All new drawings are to be created using the appropriate drawingframe template. A template file will be made available for each size ofdrawing and where necessary “Project Specific” templates will beproduced.
Template files will contain the following default data and settings:
Drawing Frames
Layers
Text Styles
Dimension Styles
Line Types
5.1.1 SSC-Template
The SSC-Templates will contain all non-discipline specific settings, and willbe used as the initial file for all discipline/project specifictemplates.

Template : Quality/W0750 – User Manual/04.04.2002
5.1.2 Drawing Frames
A template for each size of drawing will be used (e.g. SSC-STANDARD-A0.dwt).
For consistency, the drawing frame will always be placed at x=0, y=0.
All drawing will be completed in Model Space and should be drawn fullsize (refer to Section 8 for exceptions)
Drawing Limits should be set to suit the drawing frame being used.
Title block information will be inserted using the attributes assigned tothe drawing frame.
Drawing frames and associated data blocks must not be exploded.
A plot stamp will be placed on all drawings to identify the filename andlocation.
5.1.3 Layers
Standard Layer names will be preceded with “0_” (zero). This willensure that all standard layer names are displayed at the top of thelayer listing.
(The AutoCAD layer “Defpoints” is not included in this rule.)
All items should be drawn on the correct designated layer.
The preferred entity selection settings are :-
LINEWEIGHT – set to DEFAULT
LINETYPE – set to BYLAYER
COLOUR –set to BYLAYER
Only one line type should be used per layer.
The number of layers and layer settings required will differ greatlydepending upon the type of drawing being produced. Refer to thediscipline standard (Section 2.0 of this document) for further details.

Only one line type should be used per layer.
LTSCALE= 1.0
PSLTSCALE= 1.0
MEASUREMENT=1.0
All layers should have a line weight setting of “Default”.
Polylines are to be used for “thick” lines
The thickness of lines should be chosen from the following range:
0.18, 0.25, 0.35, 0.5, 0.7, 1.0, 1.4 and 2mm (BSEN 61082).
Owing to difficulties in certain methods of reproduction, the linethickness 0.18 should be avoided where possible.
6.0 EXTERNAL REFERENCES
All external reference drawings should be referenced from theappropriate Layer (0_Xref).
The preferred method of transferring drawing files should be completedusing ETransmit, this will ensure that all associated Xref drawing filesare included.
7.0 SCALES
All drawings are to be created FULL SIZE, and where necessaryscaled using view ports. If it is intended that dimensions are to bederived by measuring the drawing, a length scale bar should beincluded on the drawing.
The recommended scales used within view ports are specified in thefollowing table.
Note: Additional scales may be used, refer to the appropriateappendices for further details.

The use of associative dimensioning in Paper space is recommended.
9.0 SYMBOLS
The meaning of a symbol is defined by its shape and content.
The size and line thickness do not normally affect its meaning.
The general shape of the symbol should be maintained and, ifpractical, also the relative proportions.
In some instances, it may be necessary or advantageous to usedifferent sizes of symbols:
� To increase the number of inputs or outputs
� To facilitate the inclusion of additional information.
� To emphasize certain aspects

14.1.6 Folder Hierarchy
All drawings that have been Issued/Superseded will be removed fromthe “current status folder” and stored in the appropriate sub-folder.
14.1.7 Symbol Libraries
Only SSC Standard symbols (based on BS 1553) should always beused, unless the project indicates otherwise.
CAD Development is responsible for the creation and maintenance ofall symbol and symbol libraries.
All symbols should be according to L502 unless the project dictatesotherwise.
Symbols should not be exploded, or changed in any way.
Symbols should always be placed on the appropriate layer
14.1.8 Plotting
To maintain symbol and text integrity and consistency, all plots shouldbe produced Full Size.
All plots should use the appropriate CTB file.
A0.ctb - For Monochrome A0 size plots.
A1.ctb - For Monochrome A1 size plots.
A3.ctb - For Monochrome A3 size plots.
Layout.ctb - For Layout drawings with a feint background.
Colour.ctb - For coloured plots (created as required).
The batch plotting facility is available and will use the appropriate ctbfile as detailed above.
14.1.9 Pallets / Toolbars
SSC Standard pallets/toolbars will contain standard commands. CADDevelopment is responsible for the creation and modification of thesepallets/toolbars and these must not be modified in any way.

Project Specific pallets/toolbars will contain project specificmodifications/additions to the SSC Standard pallets/toolbars. CADDevelopment is responsible for the creation and modification of thesepallets/toolbars and these must not be modified in any way.
Users may create their own pallets/toolbars for their own use. CADdevelopment is not responsible for these.
IMPORTANT NOTE
SSC and Project pallets/toolbars must take priority over userpallets/toolbars i.e if a command occurs on the SSC Standard and theUser pallet, the SSC Standard must be used.

15.0 APPENDIX 4
15.1 PLANT DESIGN
15.1.1 Scope
This Appendix includes details for creating Mechanical and Pipingdrawings from within AutoCAD. It also includes recommended settingsfor models converted from a 3D modelling package (PDMS).
15.1.2 Draughting Procedures
� Drawing limits to be set to the size of backing sheet e.g. A0 is 1189 x 841mm.
� Draw with Snap switched ON (should be set to an integer i.e. not 2.5).
� Draw with Ortho switched ON, Mirror text (Mirrtext) OFF and Blipmode OFF.
� Plot to Limits.
� Stamp office copies and file originals in accordance with D.O. Procedures.
15.1.3 Templates
All drawings will be produced using the latest SSC Standard templateSSC-MECHANICAL-PIPING.dwt.
Where appropriate “Project Specific” templates will be produced byCAD Development.
(Refer Section 5 AutoCAD Drawing Standards)
15.1.4 Drawing Scale
All drawings are to be drawn full size.
Drawings produced using scales are unacceptable.
Scaling is to take place using the appropriate view ports andrecommended scale ratios (Refer to Section 7 AutoCAD DrawingStandards).

15.1.5 Drawing Scale
All drawings are to be drawn full size.
Drawings produced using scales are unacceptable.
Scaling is to take place using the appropriate view ports andrecommended scale ratios (Refer to Section 7 AutoCAD DrawingStandards).
15.1.6 Layers
The Simon Carves basic layers are not intended to cover thosecomponents that form the subject of the drawing; they only support itsenvironment.
Extra layers specific to the subject will need to be created such as,e.g., ‘EQUIPMENT’, ‘STEELWORK’, etc.
Sub-division of Layers
Where necessary, layer names may be sub-divided by furtherspecifying the type of component held on them. This should be done byconcatenating the relevant aspects of the components, in decreasingorder of significance, using hyphens. The following is just a sample ofpossible layer names that could be produced this way:
EQUIPMENT
EQUIPMENT-TEXT
EQUIPMENT-DIMS
EQUIPMENT-DIMS-DETAIL1
EQUIPMENT-DIMS-DETAIL2

15.1.7 Department prefixes.
When there are more than one department’s layers on a drawing ALLlayers should be prefixed by a single character code. The codedenotes which department is responsible for each layer. The codecould also be used to identify Instrument and Electrical layers on adrawing e.g. E-RouteRef and I-RouteRef.
Prefix Department
0- (Zero)General use, not reserved to any one department e.g. borderlayer
C- Civil
E- Electrical
I- Instruments
P- Plant Design

15.1.9 Model Space/Paper Space
Drawings may be produced using paper space in accordance with thefollowing criteria:
All dimensions, grid lines markers and any text on the model (i.e.Building titles etc) should be placed in model space.
All general notes should be placed in paper space.
The model should be, wherever possible, drawn at its correct site planco-ordinate or level location relative to 0,0.
15.1.10 Imports From 3D Modeling Package (PDMS)
The necessary views will be generated in PDMS and an appropriate“DXF” file will be made available.
All DXF file must clearly display the following:-
• The scale of the view. (Due to restrictions within PDMS, anyDXF views created will need to be scaled. This scale will beclearly indicated on the drawing file e.g. Scale = 1:500. Whenimported into AutoCAD, the view should then be re-set to fullsize.)
• Fixed datum point at known co-ordinate. This should be clearlyvisible and accurate, as it will be used as the insertion point.
• Layer should be created within the DXF to conform as close aspossible to the above layering structure.
• Line types used will be standard AutoCAD linetypes.
