Unit I
INTRODUCTION
Introduction to CAD – I/O devices – various graphics standards – coordinate systems – Geometric Modelling: Introduction – types of geometric modelling – wire frame – surface and solid modelling. Wireframe entities – types of curves and its mathematical representation – line- circle- ellipseparabola- Cubic spline- Bezier and B-spline (Only Basic treatment). Solid modelling entities – Solid modelling techniques- CSG and BREP – Operations performed in CSG and BREP – Extrude- sweep – linear and Nonlinear- revolve
Unit II
GRAPHIC CONCEPTS (2D and 3D)
Transformations – translation- scaling- reflection- rotation. Concatenated transformation. Inverse transformation. Hidden line removal – Z-Buffer algorithm- brief description of shading and colour rendering techniques. Manipulation and editing of entities – selection methods – dragging – clippingtrimming- stretching- offsetting- pattern- copying- deleting – regenerating- measuring. Brief description of animation- types and techniques
Unit III

Unit IV
FEM FUNDAMENTALS
Introduction to finite element method – principle- Steps involved in FEA – nodes- element and their types- shape function-constraints, forces and nodal displacements-stiffness matrix- solution techniques. Analysis of spring element. Simple problems involving stepped bars subjected to axial loading and simple structural members for triangular element
Unit V
ANALYSIS
Stages of FEA in a CAD environment – Pre-processor- solver and postprocessor. Pre-processing -FEA modelling – geometry generation- node generation- element generation- boundary constraints-load constraints- – mesh generation and refining. Solving – performing the actual analysis. Post processing – Types of 0/P available- interpretation of results. Demonstration of the above using any one popular commercial package. Other types of analysis: Brief outline of kinematical analysismanufacturability analysis and simulation.
