Sketching[ edit ] Sketch for a government building A sketch is a quickly executed, freehand drawing that is usually not intended as a finished work. In general, sketching is a quick way to record an idea for later use. Architect's sketches primarily serve as a way to try out different ideas and establish a composition before a more finished work, especially when the finished work is expensive and time-consuming. Architectural sketches, for example, are a kind of diagrams. This tool helps architects to abstract attributes of hypothetical provisional design solutions and summarize their complex patterns, hereby enhancing the design process. A sliding straightedge known as a T-square is then placed on one of the sides, allowing it to be slid across the side of the table, and over the surface of the paper. The T-square is used to hold other devices such as set squares or triangles. In this case, the drafter places one or more triangles of known angles on the T-squareā€”which is itself at right angles to the edge of the tableā€”and can then draw lines at any chosen angle to others on the page. Modern drafting tables come equipped with a drafting machine that is supported on both sides of the table to slide over a large piece of paper. Because it is secured on both sides, lines drawn along the edge are guaranteed to be parallel. Primary among these are the compasses , used for drawing simple arcs and circles, and the French curve , for drawing curves. A spline is a rubber coated articulated metal that can be manually bent to most curves.

Drafting templates assist the drafter with creating recurring objects in a drawing without having to reproduce the object from scratch every time. This is especially useful when using common symbols; i. Templates are sold commercially by a number of vendors, usually customized to a specific task, but it is also not uncommon for a drafter to create his own templates. This basic drafting system requires an accurate table and constant attention to the positioning of the tools.

A common error is to allow the triangles to push the top of the T-square down slightly, thereby throwing off all angles. Even tasks as simple as drawing two angled lines meeting at a point require a number of moves of the T-square and triangles, and in general, drafting can be a time-consuming process. A solution to these problems was the introduction of the mechanical "drafting machine", an application of the pantograph sometimes referred to incorrectly as a "pentagraph" in these situations which allowed the drafter to have an accurate right angle at any point on the page quite quickly.

These machines often included the ability to change the angle, thereby removing the need for the triangles as well. In addition to the mastery of the mechanics of drawing lines, arcs and circles and text onto a piece of paperā€”with respect to the detailing of physical objectsā€”the drafting effort requires a thorough understanding of geometry, trigonometry and spatial comprehension, and in all cases demands precision and accuracy, and attention to detail of high order.

Computer aided design[ edit ] Main article: Computer-aided design Today, the mechanics of the drafting task have largely been automated and accelerated through the use of computer-aided design systems CAD. There are two types of computer-aided design systems used for the production of technical drawings: two dimensions "2D" and three dimensions "3D". The lines, circles, arcs, and curves are created within the software.
