Technical drawing - Wikipedia, the free encyclopedia. Copying technical drawings in 1. Technical drawing, drafting or draughting, is the act and discipline of composing drawings that visually communicate how something functions or is to be constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language, and help to ensure that the drawing is unambiguous and relatively easy to understand. These drafting conventions are condensed into internationally accepted standards and specifications that transcend the barrier of language making technical drawings a universal means of communicating complex mechanical concepts. This need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanings are multiply determined. Technical drawings are understood to have one intended meaning. A professional drafter who makes technical drawings is sometimes called a drafting technician. Professional drafting is a desirable and necessary function in the design and manufacture of complex mechanical components and machines. Professional draftspersons bridge the gap between engineers and manufacturers, and contribute experience and technical expertise to the design process. Methods. 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- square. 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 . 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 paper. The lines, circles, arcs and curves are created within the software. It is down to the technical drawing skill of the user to produce the drawing. There is still much scope for error in the drawing when producing first and third angle orthographic projections, auxiliary projections and cross sections. A 2. D CAD system is merely an electronic drawing board. Its greatest strength over direct to paper technical drawing is in the making of revisions. Whereas in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2. D CAD system allows a copy of the original to be modified, saving considerable time. D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide no way to check the various components will fit together. A 3. D CAD system (such as Key. Creator, Autodesk Inventor, or Solid. Works) first produces the geometry of the part; the technical drawing comes from user defined views of that geometry. Any orthographic, projected or sectioned view is created by the software. There is no scope for error in the production of these views. The main scope for error comes in setting the parameter of first or third angle projection, and displaying the relevant symbol on the technical drawing. D CAD allows individual parts to be assembled together to represent the final product. Buildings, Aircraft, ships, and cars are modeled, assembled, and checked in 3. D before technical drawings are released for manufacture. Both 2. D and 3. D CAD systems can be used to produce technical drawings for any discipline. The various disciplines (electrical, electronic, pneumatic, hydraulic, etc.) have industry recognized symbols to represent common components. BS and ISO produce standards to show recommended practices but it is up to individuals to produce the drawings. There is no definitive standard for layout or style. The only standard across engineering workshop drawings is in the creation of orthographic projections and cross section views. Drafting can represent two dimensions (. Drafting is the integral communication of technical or engineering drawings and is the industrial arts sub- discipline that underlies all involved technical endeavors. In representing complex, three- dimensional objects in two- dimensional drawings, the objects can be described by at least one view plus material thickness note, 2, 3 or as many views and sections that are required to show all features of object. Applications for technical drawing. To communicate all aspects of the shape or design, detail drawings are used. In this field, the term plan is often used when referring to the full section view of these drawings as viewed from three feet above finished floor to show the locations of doorways, windows, stairwells, etc. It stems from the Latin ingenerare, meaning . Engineering drawings generally deal with mechanical engineered items, such as manufactured parts and equipment. Engineering drawings are usually created in accordance with standardized conventions for layout, nomenclature, interpretation, appearance (such as typefaces and line styles), size, etc. Its purpose is to accurately and unambiguously capture all the geometric features of a product or a component. The end goal of an engineering drawing is to convey all the required information that will allow a manufacturer to produce that component. Related fields. Technical illustrations can be component technical drawings or diagrams. The aim of technical illustration is . The visual image should be accurate in terms of dimensions and proportions, and should provide . The use of varying line widths to emphasize mass, proximity, and scale helped to make a simple line drawing more understandable to the lay person. Cross hatching, stippling, and other low abstraction techniques gave greater depth and dimension to the subject matter. Instead of letting the inner object shine through the surrounding surface, parts of outside object are simply removed. This produces a visual appearance as if someone had cutout a piece of the object or sliced it into parts. Cutaway illustrations avoid ambiguities with respect to spatial ordering, provide a sharp contrast between foreground and background objects, and facilitate a good understanding of spatial ordering. There are two conventions for using multiview, first- angle and third- angle. In both cases, the front or main side of the object is the same. First- angle is drawing the object sides based on where they land. Example, looking at the front side, rotate the object 9. What is seen will be drawn to the right of the front side. Third- angle is drawing the object sides based on where they are. Example, looking at the front side, rotate the object 9. What is seen is actually the left side of the object and will be drawn to the left of the front side. Section. This is often useful to show voids in an object. Auxiliary. Since the features of an object need to show the true shape and size of the object, the projection plane must be parallel to the object surface. Therefore, any surface that is not in line with the three major axis needs its own projection plane to show the features correctly. Pattern. An object is represented as if there had been a small controlled explosion emanating from the middle of the object, causing the object's parts to be separated relative distances away from their original locations. An exploded view drawing (EVD) can show the intended assembly of mechanical or other parts. In mechanical systems usually the component closest to the center is assembled first, or is the main part in which the other parts get assembled. This drawing can also help to represent disassembly of parts, where the parts on the outside normally get removed first. North America uses its own sizes. ISO . This drawing must be filed with the application. This includes practically all inventions except compositions of matter or processes, but a drawing may also be useful in the case of many processes. The Office specifies the size of the sheet on which the drawing is made, the type of paper, the margins, and other details relating to the making of the drawing. The reason for specifying the standards in detail is that the drawings are printed and published in a uniform style when the patent issues, and the drawings must also be such that they can be readily understood by persons using the patent descriptions. These parts may be used in engineering. As- fitted drawings. As- fitted drawings represent a record of the completed works, literally 'as fitted'. Mechanical Engineering Design Software .
