Hope that's clea It is representing the actual image of drawing. In drawing, the word scale not only means ruler, but also a dimension that represents the structure shown in a blueprint or plan. Name different drawing instruments. respectively. multiply the measurement on the drawing (in inches decimal equivalent) with the denominator; where the denominator is the bottom number. They are. There are typically nine types of drawing in common use, these are: 1. advertisement. Fraction Scale:5 B. Graphical Scale:6 Also Read – Types Of Surveying. This type of scale is generally used in drawing a sketch. The drawings are linked together by a master drawing or assembly drawing which gives the drawing numbers of the subsequent detailed components, quantities required, construction materia : Drawing the building plans on the drawing sheet. According to this scale, two units of measurement are represented like meter and decimeter, yard and foot or foot and inch, etc. There is a wide variation in sizes for engineering objects. An engineering scale, also known as an engineer’s scale, is actually a type of ruler that produces ratio drawings. In other words, the size of the drawing is 1/48th the size of the actual building or project. This video discuss about Scales, मापनी, Types of Scales in Engineering Drawing, Plain Scale, Construction of Plain Scale etc.. Let’s look at converting a scale drawing to a different scale. The dimensions on the horizontal and vertical axes are given from the actual scale, whereas the scale on the inclined plane is 1/2 or 2/3 of the actual scale. On a plan, al line of 22 cm long represents a distance of 440 metres. As already stated, the scale of the drawing will be indicated in the block. Designation of scales: Full size 1:1 e.g. For convenience it is generally necessary to draw them to a […] A2: Different types of lines in engineering drawing are utilized for identifying details of various objects by different line type of lines. It is required to construct a scale for this drawing that can measure in millimeters, 1/10th of single millimeter and 1/100th of single millimeters. The amount of inches to feet is written in the form of 1 inch equals 10 feet or 1:10. • Graphical Scale: Scale is drawn on the drawing itself. A drawing at a scale of 1:10 means that the object is 10 times smaller than in real life scale 1:1. A design layout drawing (or design scheme) which represents in broad principles feasible solutions which meet the design requirements. Some are very large (eg. Classification of Civil Engineering Drawings . A scale is a ruler that is used for measurement in drawing. A caliper or a pair of calipers is a measurement tool that is used to measure the distance between two opposite sides of an object. Plain scales 2 . The line CD is divided into 1/10 the divisions by the diagonal BD, i.e. • Graphical Scale: Scale is drawn on the drawing itself. As already said, such a technical drawing has all the information for manufacturing a part or welding and building an assembly.The info includes dimensions, part names and numbers, etc. • Graphical Scale: Scale is drawn on the drawing itself. There are three types of scales like reducing scale, enlarging scale and full size scale. 2. 3. Engineering drawings can be created by traditional methods such as pen and paper, but are often more commonly created by CAD (computer-aided design) software. Types of Scale • Engineers Scale: The relation between the dimension on the drawing and the actual dimension of the object is mentioned numerically (like 10 mm = 15 m). of any suitable length along this perpendicular and mark C. 5 . Architectural scales units are based on foot/inch dimensions. Standard Scales for Architectural Drawings has a lot of importance:- Before planning for a building, the scale needs to be set to make the work easy. The scale 1/4 inch = 1 foot 0 inches means that 1/4 inch in the drawing equals 1 foot in the actual building--or is drawn 1/48 size. Drawing board, drawing sheet, mini-drafter, scale, pencil and sand paper block, cello-tape, eraser and compass. 1:1 B. In Engineering Drawing, we have to draw and understand the largest buildings on a drawing sheet, not by reducing the dimensions but by reducing the scale. Plain scales are used to read lengths in two units such as meters and decimeters, centimeter and millimeters etc., or to read to the accuracy correct to first decimal. •Front drawn as front view and horizontal edges drawn at a 45 degree angle to give the impression of depth. An engineering drawing is a type of technical drawing that is used to convey information about an object. Generally, they are made of high impact lightweight plastic and/or aluminum with printed graduations that make them durable and stable for accuracy and longevity. 4 Types of Drawings •4. 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. The scale and the size of the object in turn, will decide the size of the drawing. Numerical Scale:3 1. 2.4. Construct the scale similar to distance scale. The metric system is the standard measurement throughout most of the world, so it is useful for engineers to know how to use a metric scale as well as an engineering scale that uses it. • Drafting Standard (AS1100) : This is effectively covered in prescribed texts. satyendra; March 8, 2017; 0 Comments ; Assembly drawing, Civil drawing, control drawing, Engineering drawing, GA drawing, piping and instrument drawing, process flow diagram, schmatic diagram, single line diagram, structural drawing, Technical drawing, wiring list,; Technical Drawings and their Types. Architect scale or engineer scale ruler is a specialized ruler determined to ease the drafting, measuring, or estimating in an architectural drawing, blueprint or orthographic projection. The architect's scale is used to draft plans of large and smaller scale projects. A good draughtsman can plot a length to accuracy within 0.25 mm. You could also say, 1 unit in the drawing is equal to 10 units in real life. So once a manufacturing engineer gets the drawing, he can start the production process without a second thought. CONSTRUCTION: Draw a line 15 cm long and divide it in 6 equal parts. In Drawing Lines are with dark it is representing the actual image of drawing. The scale of drawings is described as a ratio using the notation: A distance at full size : The distance at the scale used that would be the same length. Lesson 1. Explain the types of scale uses in engineering drawing 1 See answer hassanhassanazeemi is waiting for your help. There are different types of pencils and their uses in drawing. This means that … Pencil is popularly known as the simplest artistic media with several forms. There are different types of architectural drawings with different names such as plan, elevation, section etc. measure 0.1CD, 0.2CD, etc. Engineer’s Scale: In engineer’s scale, the scale of a map or drawing is the proportion which every distance on the map or drawing bears to the corresponding distance on the ground. Each scale, except the 1/16 scale, are actually two scales because it can be read from left to right or from right to left. The Purpose of Engineering Drawings. This means that 1” on the drawing represents 100’ in the real world. It ranges from graphite to charcoal. In this drawing, one axis is horizontal, and the other is vertical while the third axis is from 30° to 60° to the horizontal line. Aero planes, rockets, etc) Some are vey small ( wrist watch, MEMs components) There is a need to reduce or enlarge while drawing the objects on paper. Types of Scale • Engineers Scale: The relation between the dimension on the drawing and the actual dimension of the object is mentioned numerically (like 10 mm = 15 m). To take measurements from such a drawing a ‘Scale Rule’ is used. Her work has been published on various websites. Civil Engineer’s Scale • Full Divided Scale • 1” is divided into equal decimal units of 10, 20, 30, 40, 50, 60 and 80 divisions. Designers represent data both internally, in their minds, and externally on paper, a computer screen or other media. SCALE 1: × for reduced scales. a) Scale: - 1cm = 1m or 1cm=100cm or 1:100 b) Representative Fraction: - (RF) = 1/100 (below one) i.e. But the change is while representing the drawing on a sheet. Recommended Scales: The recommended scales for use on technical drawings are given in Table. Each scale, except the 1/16 scale, … : Drawing a pen profile on the drawing sheet. Engineer scales are used by engineers for measuring water mains, roads and various topographical features on drawing and blueprints. Drawing number; Scale; Symbol which denotes the method of projection; Name of the firm; Initials of staff working who have designed, checked and approved; Q2: What are the different lines in engineering drawing? For general engineering drawings, the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. A scale is a dimension that represents the structure shown in a plan. Usually, a number of drawings are necessary to completely specify even a simple component. Reducing scale: When the dimensions on the drawing are smaller than the actual dimensions of the object. A plain scale is simply a line which is divided into a suitable number of equal parts, the first of which part is further sub-divided into small parts. Roknuzzaman, Department of Civil Engineering, HSTU Page 67 fExample 6.12: An engineering drawing is prepared for microscopic parts of a machine. other rfs are described as 1:10, 1:100, 1:1000, 1:1,00,000 scales dimensions of large objects must be reduced to accommodate on standard size drawing sheet.this reduction creates a scale of that reduction ratio, which is generally a fraction..
