How to Read Engineering Drawings - A Simple Guide 21/4/2023
How to Read Engineering Drawings - A Simple Guide You don’t have to be an engineer to be able to read engineering drawings, while learning how to read engineering drawings can be a big advantage for you in your work. To get more news about engineering drawing symbols, you can visit runsom.com official website. What are engineering drawings used for? Engineering drawings (aka blueprints, prints, drawings, mechanical drawings) are a rich and specific outline that shows all the information and requirements needed to manufacture an item or product. It is more than simply a drawing, it is a graphical language that communicates ideas and information. 3D models are good to have and are usually (especially nowadays) used in conjunction with drawings. They are a good visual representation of the desired item, but do not contain all the information that drawings do. These blocks contain essential information about the assembly. They are usually located in the bottom right-hand corner of the drawing. These blocks provide details about what the drawing is for, for whom, part number and description, as well as information about the material and finish. Start off by reading the title block found at the bottom right-hand corner of the drawing. There are other information blocks like it, but the title block serves as the context in which the drawing should be perceived. Note that any information in the notes outside the title block that conflicts with the information in the title block should be considered as the right information and supersede the title block information. Revision block The revision block, located in the upper right hand corner, shows details about the changes that were made to roll the revision. The Revision Block includes the revision, the description of what changes were made, the date of the revision, and approval of the revision. Bill of Materials (BOM) Block Located usually either just above the title block or in the upper left-hand corner, the Bill of Materials block (also known as a BOM, Schedule or Parts List) contains a list of all the items and quantities that are required for the project or assembly. This is used for parts that either require assembly or when hardware should be added to the part. Now it’s time to try to visualize how the assembly is supposed to look like in 3D (for this you can ignore the exact dimensions). Most new drawings will have an isometric view to guide you. You can use the Bill of Materials to find the components in the drawing in order to understand the role they play in the assembly. Remember that reading an engineering drawing can take a long time, depending on the complexity of the assembly and the experience of the reader.
