It is not surprising that technical drawing demands the use of several tools. As the sheets used for technical drawing are larger, you need a special drawing table to lay it down properly. Having pins on the four corners of the sheet will help you keep it from moving. For engineering drawings, you will also need a drafting scale. Apart from these, you will also need things like rulers and squares, lettering guides, drawing pencils, and drawing templates. However, these days a lot of drawings are done on computers, and you don’t need any of these for that.
