Mechanical Engineering drawing is a type of technical drawing that helps analyze complex engineering systems. A drawing of a rectangle could be understood as part of a bar of rectangular cross-section, or it might be the front elevation of a cylinder. (adsbygoogle = window.adsbygoogle || []).push({}); Lots of symbols are also utilized in the engineering drawing which range from rectangles, circles, and triangles. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal. ... READ PAPER. Revision: Identifies the correct version of the drawing, as it may have been revised several times. The Mechanical Engineering Branch, Mechanical Systems Division, has been delegated the responsibility for interpretation, periodic updates, and distribution of the GSFC Engineering Drawing Standards Manual. What are tolerances? Lots of symbols are also utilized in the engineering drawing which range from rectangles, circles, and triangles. Standards – set of rules that govern how technical drawings are represented.. 23 This is called the drawing, a visual representation of the project with dimensions and appropriations so that civil engineers can understand what the architect actually wants them to build.. To make sure there is no misinterpretations, one needs to follow some basic steps to understand the drawing. Tolerances can be indicated as a unilateral tolerance or a bilateral tolerance. If you are a civil engineering student or a fresh civil engineering graduate, then this course is for you. This video discusses the basics of reading engineering drawings. Tolerances refer to the amount a dimension my vary from it’s maximum to its minimum value. Unilateral Tolerance The Unilateral Tolerance (as shown) indicates the base dimension and how much the actual manufactured dimension may vary from this dimension. 1. An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project. 03-1 - Goal of an Engineering Drawing - How and Why We Use Engineering Prints. Start by looking at the Title Block on each drawing. If the scale is not clearly visible on the drawing, talk with the concerned engineer for amendment. They must be concise, accurate and coordinated so the engineering drawings can be interpreted correctly and confusion can be avoided. They are a good visual representation of the desired item, but do not contain all the information that drawings do. It is crucial that you read everything and understand it before you estimate or start the construction project! Contents: reprographics, engineering drawing, sketching, pictorial projections, paper sizes, scales, conventions in layout, lettering and representation of components, tolerances, assembly drawings, K-parts list, exercises in machine drawings, structural drawings and design. Saved by Tiffany Wilson. Let’s start with 10 simple questions. 1.4 STATE the purpose of the notes and legend section of an engineering drawing. The piping and instrumentation diagram is also known as the Process engineering flow scheme which is PEFS. To learn the detail process to study drawing, watch the following video tutorial. To read a P&ID drawing, you must know what each symbol means and how each symbol is constructed. This information is displayed in the areas surrounding the graphic portion of the drawing. They are made from a series of lighter long and short dashes. You will also see real-life applications of those drawings. The first step in any construction project is to prepare a visual plan for the building. This course is intended to teach you how to read all kinds of structural drawings. Engineering Drawing is the most effective and powerful mode of communicating engineering content for engineers in a consistent and uniform manner. Q3 - Goal of an Engineering Drawing - Quiz.
