What are two ways of producing technical drawing?

Two common ways of producing technical drawings are hand drafting and computer-aided design (CAD). Hand drafting involves using traditional tools like pencils, rulers, and compasses to create precise drawings on paper. In contrast, CAD software allows for the creation of detailed and accurate drawings digitally, enabling easy modifications, 3D modeling, and enhanced collaboration among team members. Both methods serve to communicate design specifications effectively in engineering and architectural projects.
