SENG 105: Engineering Graphics


Objectives: This is an introductory course in computer aided graphics and design for engineers. This course will introduce students to modeling techniques for engineering parts and assemblies, and its application to real life engineering problems using a computer aided design (CAD) software. It will familiarize students with 3-D solid modeling and conventions of 2-D graphical representation of engineering components. As part of the course, there will be a group design project that will produce a drawing package of an appealing, functional, and marketable mechanism or device.

Description: The course will cover: Introduction to Engineering Graphics (graphics communication, traditional and CAD approaches and tools, evolution of CAD (wireframe modeling, surface modeling, solid modeling, primitive modeling, constructive solid geometry (CSG) modeling, feature based modeling, etc.); Sketch Tools (lines, arcs, circle, rectangle, fillet, chamfer,  sketch relations, smart dimension, pattern, mirror, offset entity, trim, etc.); Parts Modeling Techniques (extrusion, revolve, sweep, loft, shell, hole wizard, pattern, rib, mirror, fillet, chamfer, etc.); Detailed Part Drawing (Projection theory and types: perspective, parallel, orthogonal, axonometric, isometric, dimetric, trimetric, Multiview, line types and conventions, types of projection, sheet format: title block and border line, scale, section view, detailed view, dimensioning and tolerancing: ANSI and ISO drafting standards, size and geometry tolerancing (limit, unilateral, bilateral, general tolerance, etc.); Assembly Modeling (standard mating techniques and exploded views); Detailed Assembly Drawing (balloons, BOM, exploded view, reference dimensioning, sheet format).
