Drawings should have symbols that are:

In the context of drawings used in the industry, symbols play a crucial role in conveying information clearly and effectively. When symbols are universal, it means they are widely recognized and understood across different regions and by various professionals. This universality is essential because it minimizes the risk of misinterpretation, ensuring that everyone involved—engineers, architects, contractors, and clients—can understand the same information without confusion.

Universal symbols facilitate collaboration and communication among stakeholders, which is particularly important in complex projects where multiple disciplines may need to work together seamlessly. Having a standard set of symbols helps to maintain consistency across different documents and formats, making it easier for individuals to read and interpret drawings regardless of their background or expertise.

In contrast, complicated and detailed symbols may hinder understanding and can lead to errors in interpretation. Color coding can enhance clarity but is not always the most effective method for ensuring that symbols are understood universally. Additionally, symbols that are specific to a project may not be readily understood by individuals who are not familiar with that particular project, reducing their effectiveness. Thus, the emphasis on universal symbols is critical to ensuring clear and accurate communication in technical drawings.
