A drafting machine is a tool used in technical drawing, consisting of a pair of scales mounted to form a right angle on an articulated protractor head that allows an angular rotation. [ 1 ] [ 2 ] The protractor head (two scales and protractor mechanism) is able to move freely across the surface of the drawing board , sliding on two guides ...
Traditional drafter at work A drafter in Portugal in the 1970s, using a drafting machine. A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman, drafting technician, or CAD technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or CAD designs for machinery, buildings, electronics ...
Modern drafting tables are 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. [3] The drafter uses several technical drawing tools to draw curves and circles.
A drafting machine is a device which is mounted to the drawing board. It has rulers whose angles can be precisely adjusted with a controlling mechanism. [5] There are two main types of apparatus: an arm-type parallelogram apparatus based on a hinged arm; and a track-type apparatus which moves on a rail mounted to the top of the drawing board ...
The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used. [2] Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of ...
And the metric technical pens were chosen in sizes so that one could add detail or drafting changes with a pen width changing by approximately a factor of the square root of 2. A full set of pens would have the following nib sizes: 0.13, 0.18, 0.25, 0.35, 0.5, 0.7, 1.0, 1.5, and 2.0 mm.
Drawing boards changed as a result of technical pens—a hard (not spongy) surface was required, and when plastic film was used, the static attraction between plastic cursors, T-squares, set-squares etc. meant that as one lifted the edge from the film, the film would rise through static attraction and the ink would blot.
The American Design Drafting Association (ADDA) has developed a Drafter Certification Test. The test assesses the drafter's skill in basic drafting concepts: geometric construction, working drawings, and architectural terms and standards. The test is administered periodically at ADDA-authorized sites. [3]
