Trent produces highly detailed General Arrangement drawings through which the design development of projects is agreed. GA's are issued to the project team for information exchange and approval.Shop drawings (we call them unit details) are internal production documents.

1. Part of the project documents put in place by the owner and/ or design professionals which, in combination with written specifications, define the scope, quality assurance, requirements, submittals, field dimensions, product handling, and product specifications to the woodworker. 2. Shop drawings are detailed engineering drawings produced by the woodworker for the fabrication of the architectural woodwork products, and often submitted to the owner and/or design professional for approval.

Drawings (or photographs) disclose the industrial design and are a basic requirement of a design application.

Some items at DSCR are required to be manufactured in accordance with a drawing. The drawing may have been designed by a government agency or a commercial vendor. If a drawing is cited in the AID, the vendor is responsible for assuring the product he offers meets the standards and requirements of the drawing.

Construction drawings show where to build the project, sizes, shapes, and which products to use where. Drawings are almost always prepared on large-size sheets (24 by 36 inches is common) and often are prepared using CAD, plotted (printed), and reduced in size before reproduction. The dividing line between what should be shown on drawings versus shown in the specifications is not absolute. Drawings are used for other purposes than construction, such as for owner review, for cost estimator information, and for approval by code authorities. In these cases, the type of drawing required is determined by the audience and the contractual relationships, if any, between the drawing preparer, the owner, and the audience.
