In technical drawing, symbols are used to convey specific information clearly and concisely. Common symbols include dimension lines, projection lines, and section lines, which indicate measurements and views. Additionally, standard symbols represent features like welds, holes, and surface finishes. These symbols help ensure that drawings are universally understood by engineers, architects, and manufacturers.

The National Electrical Code (NEC) does not specify a universal set of electrical drawing symbols for all cases. Instead, it provides guidelines and requirements for electrical installations, while the symbols used in electrical drawings can vary by region, standard, or organization. Different industries and local codes may adopt their own sets of symbols, so it's important to refer to the specific standards relevant to a project.
A short break line on a drawing of a machine part is used to indicate that a portion of the part has been removed for clarity, allowing the viewer to focus on the relevant details without clutter. It visually represents that the part continues beyond the drawn area, preventing the need for a full representation of long components. This helps to save space on the drawing while providing essential information about the part's geometry.
Different symbols and abbreviations on drawings are used to convey complex information succinctly and clearly. They enhance readability and ensure that essential details can be communicated quickly, without cluttering the drawing with excessive text. This standardized approach also helps facilitate understanding among diverse stakeholders, such as engineers, architects, and contractors, who may interpret the same symbols consistently. Overall, it streamlines the design process and enhances efficiency in communication.

Machine drawing may be defined as the representation of a machine component or machine by lines according to certain set rules. A machine drawing generally gives all the external and internal details of the machine component from which it can be manufactured. The machining symbols, tolerances, bill of material, etc. are specified on the drawing. The-relative position of the different components and to make assembly drawing are also specified. IS: 696-1972 is the BIS Code for Machine Drawing.

The name for the explanation on a map of the symbols and scale used in drawing that map is a "map key" or "legend." This key provides understanding of how to interpret the various symbols, colors, and markings on the map. It helps users navigate and understand the information presented on the map more effectively.
Standard drawing conventions are used to update professionals on the correct features, abbreviation, symbols, and dimensions used. Any changes or updates from American National Standards Institute on drawing will be reviewed at standard drawing conventions.
Safety symbols usually appear in text books either to let you know what they look like, or as a means of drawing your attention to a paragraph or section related to that aspect of safety.
