ARTICLE 2: LINE - The Point Extended



If point is position, line is direction, movement, and edge. Ching says: A line is a point extended, it has length but no width. But in architecture, line becomes wall, becomes beam, becomes path.

Lines do three jobs: 1- Connect points, 2- Define edges, 3- Create movement. A line on plan is a wall. A line in section is a floor. A line in city is a street.

There are three types of lines in architecture: The physical line - actual wall or column line. The implied line - line you feel but not built, like line of columns creating edge of space without wall. The measured line - grid line, property line, setback line.

Most Egyptian site problems come from ignoring implied lines. You build wall exactly on property line (physical line) but forget street line (implied line of neighborhood). Result: building sticks out, looks wrong.

Ching teaches: Line weight matters. Thick line = cut, heavy, important. Thin line = beyond, light. Dashed line = hidden, future. If you use same line weight for everything, drawing is unreadable.

For technical office: Your line types library is your language. If contractor cannot read line hierarchy, he builds wrong. Create standard: Wall cut = 0.6mm, furniture = 0.18mm, grid = 0.09mm dashed. Consistency saves hours.

The exercise: Take any plan you admire, trace its lines with marker, only lines, no fill. You will see its soul. Great plans have few, confident lines. Bad plans have many, nervous lines.
