DSGN06070 2013 Design 101

Demonstrate an understanding of the design process.

Produce freehand engineering sketches of individual parts.

Use a 3D solid modelling CAD system to efficiently produce models of individual component parts.

Create fully dimensioned detail drawings of individual component parts for products encountered in mechanical engineering and manufacturing industry.

Read and interpret engineering drawings.

In addition to the normal CAD lectures and practical classes, Designers / Engineering Practitioners working in industry will be invited as guest lecturers and site visits to companies will be arranged, where possible.

Assessment will involve the assessment of all assignments undertaken in class, design project activity completed independently and an end of term assessment test.

The Design Process: The nature of design, design process models, design activities.

Freehand Sketching: Freehand sketching techniques, quality of presentation, line styles and thicknesses, orthographic projection – 1st and 3rd angle projection, sketching of individual parts.

Computer Aided Design: Introduction to a CAD system, parametric, feature based modelling, interface, feature manager, graphics pane, viewing options, 2D sketching techniques, origins, reference planes, reference geometry, sketch relations, dimensioning, fully defined sketches, introduction to 3D modelling tools and techniques, efficient design approach, design intent, file management.

 Engineering Drawing: ISO standards and conventional representation, 1st and 3rd angle projection, section, detail and special views, creation of detail drawings of individual parts, dimensioning tools and techniques, layout and presentation, annotations on detail drawings, printing and plotting drawings.

Reading Drawings: Principles of presentation, shape description, dimensions and tolerances - size description, symbols, standards and conventions, plane geometry.

Individual Design Project Work: Design brief, design specification, concepts and alternatives, concept sketches, evaluation of alternatives, details drawings, project reports and presentations.

As the module focus is mechanical design, the material covered will integrate mechanical engineering design philosophy, introduce students to common mechanical features and the reasons for their use, and highlight the approach adopted by mechanical designers.
