Drafting Technology Question
Bank
Course Introduction
Drafting Technology is an applied course focusing on the fundamental principles and techniques used in preparing technical drawings and plans necessary for the construction and manufacturing industries. Students learn to interpret and create two-dimensional and three-dimensional drawings using manual drafting tools and computer-aided design (CAD) software. Emphasis is placed on industry standards, geometric construction, precision, scaling, dimensioning, and the communication of engineering and architectural concepts. The course equips learners with the skills needed for careers in engineering, architecture, construction, and related fields, highlighting the importance of accuracy, clarity, and creativity in technical documentation.
