Design Graphics Mech 289 By Nabil Shalabi Jan 28 th 2008

Module 3 part 1 Solid works and its applications Module objectives: Learn how to use solid works effectively Apply the knowledge to real life problems Learn company standards for machine drawings Design for manufacturing (integrating this course with Machine tool lab)

Lecture outline Why use CAD design (examples of software) Examples of CAD models Introduction to solid works Class Exercise Class project Assignment CAD1

Computer Aided Design CAD creating 3 dimensional designs of solids and surfaces these designs can be used for Simply a 3D look of a design (for fun) Creating manufacturing drawings for technicians to build the designs Used in other applications to create simulations of dynamic systems Used in finite element analysis of structures Examples SolidWorks, ProEngineer, AutoCAD, Catia

Examples 4:1 bevel gear reducer

Shaft bearing Mount

Space Elevator

3 dimensional Maze

Solid Works Three major categories Part –Sketch (2 Dimensions) –Extrude (3 Dimensions) Assembly Drawings

Class Exercise

Butterfly valve
