What is Engineering Drawing & Different Types of Lines in Engineering Drawing | CNCLATHING

Download as PDF. For the preparation of any drawing work, it is quite essential to use instruments correctly and accurately, in order to get the required degree of accuracy. But the accuracy of the drawing depends largely on the quality of the instruments to be used. It consists of two parts, a long strip called blade and a short strip called head or stock. The blade is fitted with an ebony or plastic piece on its upper edge to form a working edge. When, on a drawing, if a part of a line or some lines among many other lines need to be erased or modified, in normal way of erasing will damage the other nearby lines. Erasing shield is a thin metallic sheet having small openings of different sizes and shapes.

Learning Task 2. Describe lines, lettering, and dimensioning in drawings. The purpose of engineering drawings is to convey objective facts, whereas artistic drawings convey emotion or artistic sensitivity in some way. Engineering drawings and sketches need to display simplicity and uniformity, and they must be executed with speed. Engineering drawing has evolved into a language that uses an extensive set of conventions to convey information very precisely, with very little ambiguity. Standardization is also very important, as it aids internationalization; that is, people from different countries who speak different languages can read the same engineering drawing and interpret it the same way.

2.1: Line styles and types

For general engineering drawings, the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. The thickness of the lines must be chosen according to the type and size of the drawing from any of the six groups given in Table 1. In the case where other types thickness of lines are used for special cases, for example, electrical and piping drawings, or if the lines specified in table 2 are used for applications other than those detailed in the last column, the conventions adopted must be explained by notes on the drawing concerned. Table 1: Thickness of lines All dimensions in mm. Read also: Dimensions and Types of Dimensioning Systems. Outline of Parts type lines represent the visible edges of the objects, hence should be outstanding in appearance and therefore, are drawn as bold i. Dimension, Projection, Leader, Hatching type lines must be drawn thin and continuous.

In engineering drawing, the details of various objects are drawn by different types of lines. What types of lines used in engineering drawings and how they used? Keep reading for understanding the basic components of engineering drawing. An engineering drawing is a type of technical drawing contains all the information of a product to be machined or fabricated, the purpose is to specify the geometry necessary for the construction of the product. Standardized languages and symbols are used to describe the dimensions, parameters, and other features of the objects, which helps people to understand the drawing and manufacture the part correctly. In most cases, a simple component is specified with many drawings, which are linked together with a primary drawing or assembly drawing. In addition, besides pictographic representations, additional textual explanations can be used to convey the necessary information.

PURPOSE. In this section you will be able to recognise and interpret different line types, and the need for variation in thickness used on engineering drawings.

Такие же звезды, наверное, видит сейчас Дэвид в небе над Севильей, подумала. Подойдя к тяжелой стеклянной двери, Стратмор еле слышно чертыхнулся.

Должен быть какой-то другой выход. - Решайте! - крикнул Хейл и потащил Сьюзан к лестнице. Стратмор его не слушал. Если спасение Сьюзан равнозначно крушению его планов, то так тому и быть: потерять ее значило потерять все, а такую цену он отказывался платить.

Он стремительно развернулся и едва сдержал крик. Никого. Дэвид Беккер исчез. Тремя пролетами ниже Дэвид Беккер висел на вытянутых руках над Апельсиновым садом с наружной стороны Гиральды, словно упражняясь в подтягивании на оконном выступе. Когда Халохот поднимался по лестнице, Беккер, спустившись на три пролета, вылез через один из проемов и повис на руках.

 - А как же принцип Бергофского. О принципе Бергофского Сьюзан узнала еще в самом начале своей карьеры.

 Сидите тихо, - приказал Фонтейн. Люди на экране вроде бы сидели в каком-то автобусе, а вокруг них повсюду тянулись провода. Включился звук, и послышался фоновой шум. - Установлена аудиосвязь.

Полностью отключив электроснабжение, они могли бы остановить работу ТРАНСТЕКСТА, а вирус удалить позже, просто заново отформатировав жесткие диски компьютера. В процессе форматирования стирается память машины - информация, программное обеспечение, вирусы, одним словом - все, и в большинстве случаев переформатирование означает потерю тысяч файлов, многих лет труда. Но ТРАНСТЕКСТ не был обычным компьютером - его можно было отформатировать практически без потерь.
