Theme: Designing with CAD software

Plan:

• Plan:
• What is CAD?
• 2. ASPECTS OF CAD
• 3. LIST OF REFERENCE BOOKS

• 1.WHAT IS CAD?
• Integration of CS techniques in engineering design
• Use of computers(hardware & software)for designing products
• Numerical method, optimizations etc.
• 2D/3D drafting
• 3D modeling for visualization
• Modeling curves,surfaces,solids,mechanism,assemblies,etc.

ANALYSIS

• ANALYSIS
• Stress (deflection analysis,I.e. numerical methods,FEM
• Simulation of actual use
• Optimizations
• Applications
• CAD/CAM integration
• Process planning

2. ASPECTS OF CAD

• Modeling
• Display/visualization
• Applications
• MODELING
• Definition of objects
• Relation between objects
• Properties
• Orientations in suitable co-ordinate system
• Modification of existing definition (editing)

DISPLAY VISULIAZITION AIDS

• DISPLAY VISULIAZITION AIDS
• Display of model objects
• Mapping objects onto screen coordinates
• Surface display,shading
• Projections
• Hidden line removal when multiple surfaces are displayed

REQUIREMENTS OF MODELING

• Solids are modeled by storing information of constituent surfaces
• This help in
• Displaying surfaces(3D)
• Computing solid properties
• Modeling by storing info.on bounding curves or by storing their geometric definitions

DATA BASES FOR CAD
