Fundamentals of engineering drawing using AutoCAD. Covers multiview orthographic projection, section views, dimensioning and tolerancing per drafting standards, and the full workflow from freehand sketch to finished CAD drawing.
Multiview orthographic projection — constructing and reading top, front, and right-side views of 3D objects following third-angle projection convention.
Dimensioning and tolerancing — applying dimensions, tolerances, and geometric callouts according to engineering drafting standards.
Section views — producing full and half section drawings to reveal interior features that orthographic views cannot show clearly.
AutoCAD workflow — setting up layers, linetypes, and title blocks; using precision drawing tools; and managing drawing files to professional standards.
Sketch-to-CAD pipeline — moving from a freehand concept sketch through to a fully dimensioned, print-ready AutoCAD drawing.
Technical Drawing introduces the language that engineers use to communicate design intent. Every manufactured part starts as a drawing — knowing how to read and produce one correctly is a fundamental engineering skill.
The course covers both the theory of projection (how a 3D object maps onto 2D views) and the practical tool skills needed to execute drawings in AutoCAD. Assignments progress from simple geometric shapes to more complex machined parts including angle brackets with full dimensioning.
The skills developed here feed directly into later courses — any time a design needs to be fabricated or communicated, it goes through a drawing.
Progression of orthographic drawings for a machined angle bracket — from initial freehand sketch to fully dimensioned AutoCAD drawing with tolerances and title block.
Complete set of orthographic projections for assigned objects — top, front, and right-side views with hidden lines, center lines, and proper linetype usage.
Full and half section drawings showing interior geometry of a machined part — correctly identifying cutting planes and applying section lining per drafting convention.
