The course introduces the CAD environment, covering hardware systems, including computer specifications and input/output devices. It explores basic geometry creation (lines, circles, arcs) and modification using layers, colors, text, and dimensions. It also examines industry-standard CAD software for 2D and 3D drafting techniques, including wireframe, surface, solid, and parametric modeling. Additionally, the course addresses computer graphics concepts such as transformations, translations, and rotations. It concludes with technical drawing standards, including sectioning, assembly drawings, and standard mechanical, civil, and electrical components.
