Industrial design

One-off, batch, and mass or continuous production all have different design requirements, because of the differences between types of product, client [client: Person or organisation that wants a product manufactured - eg a retailer. ] expectation, and the scale of operation.

Drawing conventions

Conventions are ways of doing things which conform to a common standard, for example, technical drawings. Using conventions saves time and ensures that a drawing means the same thing to anyone who sees it. The BSI standard for drawings is BS8888.

The illustration below shows two drawings conforming to BS8888 specifications.

Extension lines are parallel lines that extend out from two points on the drawing. A small break should be added where the extension line meets the drawing.

Dimension lines are drawn with an arrow on either end between two extension lines, with the dimension written alongside. The unit of measurement should also be given.
