WHAT IS IT TECHNICAL DRAWING & ALPHABET OF LINE Based on the article of William Anderson of Schoolwork helper editorial team reviewed last 2019 he made mentioned that, technical drawings provide clear and accurate information how an object is to be manufactured. It shows and describes clearly and accurately the information required to build or manufacture a product. Technical drawing is a form of design communication based online symbols recognized and understood worldwide. Hence, technical drawing is often referred to as a universal language understood (readable) by anyone regardless of the language they speak. Contractors, estimators, tradesmen, and builders rely totally on technical drawings for the information they need to build, construct and manufacture a product. To work in design and manufacturing industries, the study of technical drawing –ability to prepare, read and interpret technical drawing is essential. Line symbols used in technical drawing are often referred to as ALPHABET OF LINES. The use of line symbols enables engineers/designers to express features of designed products clearly and accurately. Line features vary not only by width but also by how they are graphically represented in a drawing. Line significance is conveyed by line weight or thickness of the line. Every line is drawn at different thickness and darkness to express contrast as well as importance. Lines that are less important are thin and light. Key to successful drafting is to have a good technical knowledge of these various line characteristics – to understand where and when to apply them in technical drawing. ALPHABET OF LINE 1. OBJECT OR VISIBLE LINES – Thick dark line use to show outline of object, visible edges, and surfaces. 2. CONSTRUCTION LINE – Very light and thin line use to construct layout work. 3. DIMENSION LINE – Thin and dark lines use to show the size (span) of an object with a numeric value. Usually terminates with arrowheads or tick markings. 4. HIDDEN LINE – Short dash lines use to show nonvisible surfaces. Usually shows as medium thickness. 5. CENTRE LINE – Long and short dash lines. Usually indicates centre of holes, circles and arcs. Line is thin and dark. 5 6. EXTENSION LINE – Thin and dark line use to show the starting and ending of dimension. 7. CUTTING PLANE LINE – Extra thick line use to show cutaway views or plane of projection where a section view is taken. Arrow indicates direction of view. 8. SHORT AND LONG BREAK LINES –Short and long medium line use to show cutaway view of a long section. 9. LEADER LINE – Medium line with arrowhead to show notes or label for size or special information about a feature. 10. PHANTOM LINE – Long line followed by two short dashes use to show alternate position of a moving part. 11. SECTION LINE – Medium lines drawn at 45 degrees use to show interior view of solid areas of cutting plane line. Example: Meaning and Uses of Technical Drawing Technical Drawing is the art or skill of creating a plan as such that a person can visualize and follow how it needs to be carried out. This is also known as Drafting and through this process, instead of writing and/or explaining the process of how 6 something would be created or performed, the functions and features are explained with the help of a drawing. The person who creates these drawings are known as a draughtsman, draftsperson, or drafter and if the person is a professional, he or she is then known as a drafting technician. Technical Drawing is most practiced by architects and engineers but is also used by teachers, interior designers, product designers, construction workers, plumbers, electricians, and pretty much anyone who builds or creates things. Even programmers and app designers may use their own brand of technical drawing. 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. Basic Elements of a Flowchart According to the post of Naveen Kandwal last18th January 2014 he discussed that, a flowchart is a diagram that uses graphic symbols to depict the nature and flow of the steps in a process. Another name for this tool is "flow diagram." A flowchart is commonly used by systems analysts to visualize the series of processes in a business system. It is a useful tool to design an efficient business system and to troubleshoot or improve an existing system. It consists of elements, such as the terminator, process, sub process, decision, arrow lines, and connectors. 1. Terminator- A terminator is represented by a small rectangle with curved corners. It appears at the start and at the end of a flowchart. The end terminator appears only once on a single flowchart. 2. Process- A process is represented by a rectangle. It refers to an action in a business process. It must be described clearly and concisely. It can be described using a single verb noun phrase; for example, "Order Office Supplies." The same level of detail must be kept in processes on a single flowchart. 3. Sub-process -A sub-process is represented by a rectangle with double lines on each side. It is a major process that could be broken up into simpler processes developed into another flowchart. 4. Decision- A decision is represented by a diamond. A process that can answer a decision of "yes" or "no" requires a decision box. 5. Connector- A connector is represented by a small circle or a connector box and is labeled using letters. A flowchart written on a single page is clearer than a flowchart on several pages. It ensures that the processes are connected logically and correctly on several pages. 6. Arrow Lines -Arrow lines drawn in one direction, preferably from top to bottom keep a flowchart clear. Avoid arrow lines that loop because this could indicate redundancy in the business process. When to use flowcharts At the beginning of your process improvement efforts, an as-is flowchart helps your team and others involved in the process to understand how it currently works. The team may find it helpful to compare this as-is flowchart with a diagram of the way 7 the process is supposed to work. Later, the team will develop a flowchart of the modified process again, to record how it functions. At some point, your team may want to create an ideal flowchart to show how you would ultimately like the process to be performed. Benefits of Using Flowcharts 1. Promotes understanding of a process. People may have differing ideas about how a process works. A flowchart can help you gain agreement about the sequence of steps. Flowcharts promote understanding in a way that written procedures cannot do. One good flowchart can replace pages of words. 2. Provides a tool for training employees. Because of the way they visually lay out the sequence of process steps, flowcharts can be very helpful in training employees to perform the process according to standardized procedures. 3. Identifies problem areas and opportunities for process improvement. Once You break down the process steps and diagram them, problem areas become more visible. It is easy to spot opportunities for simplifying and refining your process by analyzing decision points, redundant steps, and rework loops. Basic Flowchart Symbols The symbols that are commonly used in flowcharts have specific meanings and are connected by arrows indicating the flow from one step to another: What is Flowchart? The flowchart is a diagram which visually presents the flow of data through processing systems. This means by seeing a flow chart one can know the operations performed and the sequence of these operations in a system. A flow chart can be used for representing an algorithm. Flowchart Symbols There are 7 basic symbols commonly used in flowcharting of assembly language Programs: Terminal, Process, input/output, Decision, Connector and Predefined and Flow lines. Symbol Name Function Indicates any type of internal 1 Process operation inside the processor or memory Used for any Input/output (I/O) operation. Indicates that the 2 Input/output computer is to obtain data or output results Used to ask a question that can be 3 Decision answered in a binary format (Yes/No. True/False) Allows the flowchart to be drawn 4 Connector without interesting lines or without a reverse flow. 8 5 Predefined process 6 Terminal 7 Flow Lines Used to invoke a subroutine or interrupt program Indicates the starting or ending of the program process or interrupt program Shows direction of flow. General Rules for Flowcharting 1. All boxes of the flowchart relate to Arrows. (Not lines) 2. Flowchart symbols have an entry point on the top of the symbol with no other entry points. The exit point for all flowchart symbols is on the bottom except for the Decision symbol. 3. The Decision symbol has two exit points; these can be on the sides or the bottom and one side. 4. Generally a flowchart will flow from top to bottom. However, an upward flow can be shown if it does not exceed 3 symbols. 5. Connectors are used to connect breaks in the flowchart. Examples are: • From one page to another page. • From the bottom of the page to the top of the same page. • An upward flow of more than 3 symbols 6. Subroutines and Interrupt programs have their own and independent flowcharts. 7. All flow charts start with a Terminal or Predefined Process (for interrupt programs or subroutines) symbol. 8. All flowcharts end with a terminal or a contentious loop. Examples of Flowcharts Example 1: Algorithm for find the greater number between two numbers. 9 Example 2: Flowchart for enlisting the work to do based on weather condition. WHAT’S MORE Test I.
