LAYOUT OF BORDERS AND TITLE BLOCK ON DRAWING SHEET

Post Summarization: ● Introduction. ● Size of drawing sheets. ● Margin. ● Borderlines. ● Title block. ● Rules for selecting Titles. ● Revision Table. ● Notes. ● Tutorial Videos (Coming Soon!) INTRODUCTION: A drawing sheet consists of an engineering drawing and must have some other aspects too i.e. Border lines, Title block, Notes, etc for better demonstration of the drawing. The layout of border lines and title blocks should always be done in some specific manner on the drawing sheet as it's not only a necessity for increasing the visual orientation of the drawing sheets, moreover, these help to read the drawing sheet more speedily in a systematic way. SIZE OF THE DRAWING SHEET: The size of the drawing sheet in detail can be found in the  TECHNICAL DRAWING AND INSTRUMENTS of this blog. MARGIN: Margin or Marginal lines are drawn on the drawing sheet only where the untrimmed size of the drawing sheet is provided. Generally, in the paper industry, trimmers are used to trim drawing sh

LETTERING

 LETTERING: INTRODUCTION Writing titles on drawing sheets, dimensions on drawing objects, special notes, and other important particulars on a drawing is called Lettering. It is a very important step in an engineering drawing. Lettering should, therefore, be done properly in a clear, legible, and uniform style. It should be in plain and simple style so that it could be done freehand and speedily. Any ornamental style must be avoided lettering in engineering drawings. Though accurate and neat drawings may be drawn yet sometimes, their appearance is spoiled by ornamental lettering or sometimes, their usefulness is decreased by poor lettering.   Note:  The use of drawing instruments in lettering takes considerable time and hence, it should be avoided to save time, especially in the examination hall. Efficiency in the art of lettering can be achieved by careful and continuous practices. **Actually, a free hand drawing means, "keeping almost the same visual shape, you can draw any comp

TECHNICAL DRAWING AND INSTRUMENTS

What is Technical Drawing? What is the necessity of Technical Drawing?  Technical drawing or drafting, is the demonstration and discipline of composing drawings that visually communicate how something capacities or is developed. Technical drawing is basic for imparting thoughts in industry and engineering. To make the drawings more clear, individuals use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page design. Together, such conventions constitute a visual language and help to guarantee that the attraction is unambiguous and moderately straightforward. A large number of the images and standards of Technical drawing are systematized in an international standard called ISO 128.  The requirement for exact correspondence in the arrangement of a practical record recognizes specialized drawing from the expressive drawing of the visual expressions. Creative drawings are emotionally deciphered; their implications are duplicated and decided. Specia

INTRODUCTION OF ENGINEERING DRAWING

INTRODUCTION OF ENGINEERING DRAWING Simply you can say, it is a special type of language globally used for engineers or technical persons to communicate between them for fulfillment of target or making any geometrical shaped object or rather say any project. Suppose, there is a building or bridge construction or maybe the construction of an electric or power substation, or maybe in a mechanical workshop, we need various types of technical persons or specialists for construction or production. As an example, some engineers ensure the stability of load capacity of the ground and how much load can bear that ground by doing the field survey, some technical persons or engineers develop the structure or construction, and some technical person completes the fabrication ( i.e. riveting or welding ) portions, some technical persons or engineers develop the electrical supply connections and so on. All technical persons and engineers come together to complete a project or projects but they all n

SCALE

INTRODUCTION TO SCALE :   Scales are made of wood, steel, celluloid plastic, or cardboard. 15 cm long and 2 cm wide or 30 cm long and 3 cm wide level scales are in Common use. They are ordinarily around 1 mm thick. However, a  15 c.m. long and 2 c.m. wide scale is considered a Standard length of scale.  By using scale, small components can be drawn with the same size as the components are actually. A 150 mm long pen or 175 mm long pencil may be shown by a drawing of 150 mm length or 175 mm length respectively. Drawings of the same size as the objects are called full-size drawings and ordinary full-size scales are generally used to draw such drawings. A scale is determined by the ratio of the dimensions of an element as represented in a drawing to the actual dimensions of the same element. This is called R.F. or Representative Fraction of Scale. The scales are generally classified as : (1) Plain scales (2) Diagonal scales (3) Vernier scales (4) Comparative scales (5) Scale of chor
