The basic drafting procedure is to place a piece of paper (or other material) on a smooth surface with right-angle corners and straight sides—typically a drawing board. 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.
A working drawing is a type of technical drawing, which is part of the documentation needed to build an engineering product or architecture. Typically in architecture these could include civil drawings , architectural drawings , structural drawings , mechanical drawings , electrical drawings , and plumbing drawings .
(Mnemonic: a "shark in a tank", esp. that is sunken into the floor.) Using the 6-sided viewing box, each view of the object is projected opposite to the direction (sense) of sight, onto the (transparent) exterior walls of the box; that is, each view of the object is drawn on the same side of the box.
Perspective – the principle of creating the illusion of 3-dimensionality on a 2-dimensional source such as paper. This is achieved by using one or more vanishing points (Line perspective), or making the atmosphere greyer, blurrier and smaller as it goes further back (Atmospheric perspective).
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
However in the documentary "Da Vinci's Machines" (2009), a team of engineers and craftsmen undertook the challenge of reconstructing Leonardo da Vinci's design for an armored vehicle, commonly referred to as his tank, the successful operation and movement of the tank by fixing the purposely placed design flaw with the gearing not only validated ...
By specifying the opening length and width, a draft angle, and a depth, it is not necessary to specify the dimensions for the internal surface, as these may be calculated from the above. The manufacture of a part that incorporates zero or negative angles may require a mold that can be separated into two or more parts, in order to release the ...
Architectural drawing, Canada, 1936. This is a simple process for the reproduction of any light transmitting document. Engineers and architects used to draw their designs on cartridge paper; these were then traced by hand on to tracing paper using Indian ink, which were kept to be reproduced with the cyano-copier whenever they were needed.
