Master Engineering Drawing with these Topics

Engineering Drawing is a technical drawing used to visually communicate the design, dimensions, and specifications of an object or structure. 🏗️📐

An Engineering Drawing syllabus typically covers a structured set of topics designed to teach students the fundamental principles of technical drawing, drafting, and visual communication used in engineering. While the exact syllabus can vary by institution and country, the following is a common outline for an Engineering Drawing course:
