Engineering drawing Wikipedia. An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items. Engineering drawing the activity produces engineering drawings the documents. More than merely the drawing of pictures, it is also a languagea graphical language that communicates ideas and information from one mind to another. Relationship to artistic drawingeditEngineering drawing and artistic types of drawing, and either may be called simply drawing when the context is implicit. Engineering drawing shares some traits with artistic drawing in that both create pictures. But whereas the purpose of artistic drawing is to convey emotion or artistic sensitivity in some way subjective impressions, the purpose of engineering drawing is to convey information objective facts. One of the corollaries that follow from this fact is that, whereas anyone can appreciate artistic drawing even if each viewer has his own unique appreciation, engineering drawing requires some training to understand like any language but there is also a high degree of objective commonality in the interpretation also like other languages. In fact, engineering drawing has evolved into a language that is more precise and unambiguous than natural languages in this sense it is closer to a programming language in its communication ability. Engineering drawing uses an extensive set of conventions to convey information very precisely, with very little ambiguity. Relationship to other technical drawing typeseditThe process of producing engineering drawings, and the skill of producing those, is often referred to as technical drawing or drafting draughting although technical drawings are also required for disciplines that would not ordinarily be thought of as parts of engineering such as architecture, landscaping, cabinet making, and garment making. Persons employed in the trade of producing engineering drawings were called draftsmen or draughtsmen in the past. Although these terms are still in use, the not gender specific terms draftsperson and drafter are now more common. Cascading of conventions by specialityeditThe various fields share many common conventions of drawing, while also having some field specific conventions. For example, even within metalworking, there are some process specific conventions to be learnedcasting, machining, fabricating, and assembly all have some special drawing conventions, and within fabrication there is further division, including welding, riveting, pipefitting, and erecting. Each of these trades has some details that only specialists will have memorized. Microsoft Windows Xp 64 Bit Iso there. An engineering drawing is a legal document that is, a legal instrument, because it communicates all the needed information about what is wanted to the people who will expend resources turning the idea into a reality. It is thus a part of a contract the purchase order and the drawing together, as well as any ancillary documents engineering change orders ECOs, called out specs, constitute the contract. Thus, if the resulting product is wrong, the worker or manufacturer are protected from liability as long as they have faithfully executed the instructions conveyed by the drawing. If those instructions were wrong, it is the fault of the engineer. Because manufacturing and construction are typically very expensive processes involving large amounts of capital and payroll, the question of liability for errors has great legal implications as each party tries to blame the other and assign the wasted cost to the others responsibility.

Standardization and disambiguationeditEngineering drawings specify requirements of a component or assembly which can be complicated. Standards provide rules for their specification and interpretation. Standardization also aids internationalization, because people from different countries who speak different languages can read the same engineering drawing, and interpret it the same way. One major set of engineering drawing standards is ASME Y1. Y1. 4. 5. M most recently revised in 2. These apply widely in the United States, although ISO 8. Geometrical product specifications GPS Fundamentals Concepts, principles and rules is now also important. In 2. 01. 1, a new revision of ISO 8. Geometrical product specifications GPS Fundamentals Concepts, principles and rules was published containing the Invocation Principle. This states that, Once a portion of the ISO geometric product specification GPS system is invoked in a mechanical engineering product documentation, the entire ISO GPS system is invoked.

The implication of this is that any drawing using ISO symbols can only be interpreted to ISO GPS rules. The only way not to invoke the ISO GPS system is to invoke a national or other standard. In Britain, BS 8. Technical Product Specification has undergone important updates in the 2. For centuries, until the post World War II era, all engineering drawing was done manually by using pencil and pen on paper or other substrate e. Since the advent of computer aided design CAD, engineering drawing has been done more and more in the electronic medium with each passing decade. Today most engineering drawing is done with CAD, but pencil and paper have not entirely disappeared. Some of the tools of manual drafting include pencils, pens and their ink, straightedges, T squares, French curves, triangles, rulers, protractors, dividers, compasses, scales, erasers, and tacks or push pins. Slide rules used to number among the supplies, too, but nowadays even manual drafting, when it occurs, benefits from a pocket calculator or its onscreen equivalent. And of course the tools also include drawing boards drafting boards or tables. The English idiom to go back to the drawing board, which is a figurative phrase meaning to rethink something altogether, was inspired by the literal act of discovering design errors during production and returning to a drawing board to revise the engineering drawing. Drafting machines are devices that aid manual drafting by combining drawing boards, straightedges, pantographs, and other tools into one integrated drawing environment. CAD provides their virtual equivalents. Producing drawings usually involves creating an original that is then reproduced, generating multiple copies to be distributed to the shop floor, vendors, company archives, and so on.

The classic reproduction methods involved blue and white appearances whether white on blue or blue on white, which is why engineering drawings were long called, and even today are still often called, blueprints or bluelines, even though those terms are anachronistic from a literal perspective, since most copies of engineering drawings today are made by more modern methods often inkjet or laser printing that yield black or multicolour lines on white paper. The more generic term print is now in common usage in the U. S. to mean any paper copy of an engineering drawing. In the case of CAD drawings, the original is the CAD file, and the printouts of that file are the prints. View and Download Cadence PSPICE SCHEMATIC user manual online.
