Technical Drawing Tools
Drafting tools may be used for measurement and layout of drawings, or to improve the consistency and speed of creation of standard drawing elements. Tools such as pens and pencils mark the drawing medium. Other tools such as straight edges, assist the operator in drawing straight lines, or assist the operator in drawing complicated shapes repeatedly. Various scales and the protractor are used to measure the lengths of lines and angles, allowing accurate scale drawing to be carried out. The compass is used to draw arcs and circles. A drawing board was used to hold the drawing media in place; later boards included drafting machines that sped the layout of straight lines and angles. Tools such as templates and lettering guides assisted in the drawing of repetitive elements such as circles, ellipses, schematic symbols and text. Other auxiliary tools were used for special drawing purposes or for functions related to the preparation and revision of drawings. The tools used for manual ...

Technical Drawing
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is 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. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The 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 draftsman is ...

William Stanley (inventor)
William Ford Robinson Stanley (2 February 1829 – 14 August 1909) was an English inventor with 78 patents filed in both the United Kingdom and the United States of America. He was an engineer who designed and made precision drawing and mathematical instruments, as well as surveying instruments and telescopes, manufactured by his company "William Ford Stanley and Co. Ltd." Stanley was a skilled architect who designed and founded the UK's first Vocational school, Trades school, Stanley Technical Trades School (now Harris Academy South Norwood), as well as designing the Stanley Halls in South Norwood. Stanley designed and built his two homes. He was a noted philanthropist, who gave over £80,000 to education projects during the last 15 years of his life. When he died, most of his estate, valued at £59,000, was bequeathed to trade schools and students in south London, and one of his homes was used as a children's home after his death, in accordance with his will. Stanley was a m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
