Surfaces of double curvature (domes, etc.) cannot be developed with complete accuracy, nevertheless the method illustrated in 347 is sufficiently accurate for most practical purposes. Assuming that a hemisphere has to be developed to provide the exact shapes of the constructional ribs and of the covering veneers, first draw the elevation and divide horizontally into any number of zones A, B, C, D, E, F, etc. The outer circumference of the dome is then drawn on plan, and the zones in elevation pro­jected downwards to the corresponding circles on the plan B, C, D, E, and F. The circle on plan is then divided into any number of equal parts 1, 2, 3, 4, 5, etc., and the radii drawn in...

A cone is a pyramid with a circular base (345:1), and a vertical cut through the axis will yield a section which is a triangle, parallel to the axis a hyperbola, and parallel to one of the sides a parabola. If the cut is parallel with the base then the section will be a circle (345:2), and inclined to the base an ellipse. Of these conic sections the ellipse is of considerable importance in the setting out of oval-shaped work, gate-leg tables, etc., and although it can be drawn by hand it is more satisfactory to construct it geometrically.


Several methods are available of which the foci method (345:3) is the most common. The major axis which is to be the larger diameter of the ellipse is drawn first, and the minor axis at right angles to it...

IN THE FIRST HALF of the 20th century, lighting design was a separate discipline to furniture design, with designers rarely straddling the boundary between the two. The post-war generation of designers, however, considered both to be branches of industrial design.

The greatest draw of lighting design was the scope for decorative expression it allowed. As Achille Castiglioni, one of the most celebrated designers of the period, put it, “the interest [in lighting design] was not so much centred on solving the problems of lighting…as on emphasizing the decorative qualities of fixtures when they are without light”. Italy led the way in post-war lighting, with companies such as O – Luce, Fontana Arte, and Stilnovo.

Initially, the preferred look was one of elegance, symmetry, and restraint...

The various terms used in connection with circles are illustrated in 343. Arc, any part of a circumference; chord, any straight line shorter than the diameter terminated by the circumference at both ends; diameter, a chord which passes through the centre of a circle; radius, a straight line drawn from the centre of a circle to the circumference and therefore half the diameter; normal, a straight line drawn from any point on the circumference radial to the centre; tangent, a straight line touching the circumference at any one point at right angles to a normal at that point (343:1). Quadrant, a sector which is a quarter of a circle; semicircle, a segment which is a half of a circle; minor segment, part of a circle contained between a chord and its arc and less than a semicircle;

major segmen...

THE SUDDEN SURGE IN popularity of the coffee table in the post-war years can be directly attributed to the rise of the television. The presence of a television set in a house tended to pull families away from the dining room at mealtimes and into the living room, where the coffee table proved the ideal object on which people could place their plates.

Such was the increased traffic in the living room, thanks to the TV, that the most popular style of coffee table quickly became one on which you couldn’t hurt your shins – that is, one without sharp corners...

Parallelograms are quadrilaterals with opposite sides equal and parallel to each other, therefore the opposite angles are equal, the diagonals bisect the figures into similar triangles and also bisect each other. They are simple to construct as shown, where 341:4 is a square, 341:5 a rectangle, 341:6 a rhombus and 341:7 a rhomboid.



342 Polygons


Regular polygons—a pentagon has five sides (342:2A), a hexagon six sides (IB), a heptagon seven sides (1C), an octagon eight sides (1D), etc.—have more than four sides, the sides are equal and the angles also equal. All the corners must, therefore, lie on the circumference of the


circumscribing circle, and given the circle it is only necessary to divide the circumference into equal parts represen...
