3.3 DEFINITIONS. (Alphabetically Listed)
3.3.1 Engineering Drawing. An engineering drawing is an engineering document or digital data file(s) that discloses by means of pictorial or textual presentations, or combinations of both, directly or by reference, the physical and functional end product engineering requirements of an item.
3.3.1.1 Dimensioned Drawing. A drawing depicting a design with the size given, as applicable, by means of dimensions.
3.3.1.2 Un dimensioned Drawing. A drawing depicted to a precise scale on environmental stable material and used for printed circuits and loft line information and fabrication of templates, patterns, or printed circuits.
3.3.1.3 Digital Data (Digital Drawing). Engineering drawings prepared by other than manual means (such as computer-generated drawings) shall provide all of the information required by the particular drawing type or level of design disclosure. Minor variations from the requirements as specified herein to accommodate document preparation are acceptable as long as these variations meet the requirements relative to the information contents.
3.3.2 Enlargement Scale. A scale where the ratio is larger than 1 to 1 and the object presentation increases in size as the ratio increases.
3.3.3 Full Size. A scale with a ratio of 1 to 1 or actual size.
3.3.4 Layout Drawing. A drawing clearly showing the shapes, sizes, location, clearances, and materials of a design and its adjacent parts. Layouts are used to convey information to customers, vendors, and as a master drawing from which "production" drawings are prepared. Layout drawings are not released for the manufacture of parts.
3.3.5 Production Drawing. An engineering drawing that discloses the physical and functional engineering end product requirements for parts, assemblies and installations required for the manufacture or assembly of an experimental or production model end item. They are released, controlled and normally required for customer submittal.
3.3.6 Reduction Scale. A scale where the ratio is smaller than 1 to 1 and the object presentation decreases in size as the ratio decreases.
3.3.7 Scale. The ratio of the size of an object represented on a drawing compared to the actual size of the object.
