製図 (せいず, seizu) refers to the practice of technical drawing or drafting, which is essential in fields like architecture, engineering, and design. It involves creating detailed representations of objects, structures, or systems, often using specific symbols and scales to convey precise information. This process is crucial for communicating ideas and plans clearly, ensuring that everyone involved in a project, from architects to builders, understands the specifications. Tools such as コンパス (compass), 定規 (ruler), and CAD software (computer-aided design) are commonly used in製図 to enhance accuracy and efficiency.
