Line Types [edit]
Standard widths: 0.13mm, 0.18mm, 0.25mm, 0.35mm, 0.50mm, 0.70mm. These are designed to be scaled to different ISO standard paper sizes and still be of a standard width (i.e. there is a multiplier of √2 between each).
| Use | Width | Example | SVG style guide |
|---|---|---|---|
| Page & title box borders | 0.70mm |  |
stroke-width:0.70mm; stroke-linejoin:bevel |
| General Outlines | 0.35mm |  |
stroke-width:0.35mm; stroke-linejoin:miter |
| Hidden Outlines | 0.35mm |  |
stroke-width:0.35mm; stroke-linejoin:miter; stroke-dasharray:7,2 |
Title Blocks [edit]
Include enough information to enable the drawing to be completely understood. I no particular order:
- Context (of the subject);
- Draughtsperson;
- Scale;
- Date;
- Revisions;
- Title;
- Units (if other than milimeters);
- Copyright (of both the drawing and the design);
- Reference number; and
- URL.
A title block should not exceed 170mm in width.
Representation of Materials [edit]
Brickwork [edit]
Brickwork in section is represented by parallel 0.35mm lines, outlining the actual (i.e. scaled) width of the brickwork, with double 0.25mm lines crossing at 45˚, spaced three line-thicknesses apart and such that one pair starts 1/3 of the wall thickness from where the previous pair met the opposite line.
