Advanced Geometry and Orthographic Projection

This topic includes constructing special curves, plotting loci, producing pictorial drawings with circles and arcs, drawing exploded views, and creating assembly drawings through orthographic projection. These advanced drawing techniques are critical for technical communication and are heavily assessed in ECZ Graphic Communication papers. Mastery supports precision in engineering and manufacturing drawings, aligning with Zambia's CBC goals of developing high-level graphic skills for vocational and academic progression.
