Blueprint Reading and Sketching

Master Engineering Drawings and Communicate Design with Precision.

Blueprint reading and engineering drawing are foundational skills in mechanical engineering, manufacturing, product design, and industrial systems development.

This Blueprint Reading & Technical Drawing course at UC San Diego Extended Studies prepares students to read, interpret, and create industry-standard engineering drawings using ASME Y14 and ISO drafting standards .

Students gain practical experience in orthographic projections, sectional and auxiliary views, dimensioning and tolerancing (GD&T principles), surface finish symbols, welding symbols, fasteners, gears, bearings, and piping schematics, while developing both freehand sketching and CAD-supported drafting skills.

Whether you're an engineering student, technician, CAD professional, or working in manufacturing, this course will elevate your technical communication skills immediately.

What You Will Learn in This Engineering Drawing Course Engineering drawing terminology and drafting fundamentals ASME Y14 and ISO standards compliance Sectional views and auxiliary views Dimensioning, tolerancing, fits, and allowances Surface texture and material specification symbols Welding symbols and weldment drawings Fasteners, threads, gears, and bearings representation Piping diagrams, hydraulic and pneumatic schematics 2D to 3D visualization and CAD drafting fundamentals Why Blueprint Reading Skills Matter in Mechanical Engineering Engineering drawings are the universal language of manufacturing and design.

Employers in Aerospace, Automotive, Robotics, Industrial manufacturing, Energy systems and Product development require professionals who can interpret and produce accurate, standards-compliant technical drawings.
