Geometric modelling:
Geometric modelling is an integral part of any Computer-Aided-Design (CAD) system. Integration of geometric modelling; computer graphics along with design principles develops CAD tools. Therefore, in this unit, a brief treatment of representation of curves is presented. Curve representation in parametric form would increase the graphical representation of curves apart from ease of computation. Synthetic forms of curves such like Hermite cubic B-Splines, Bezier, B-Splines and Nurbs have been extensively used to represent several practical situations being modelled in CAD systems. A detailed treatment of these curves is presented. The features of Wire-frame models and its applications are also discussed.
What is Wire-frame Wire-frame models use the simplest data structures and they are ambiguous. Wire frame is a well-known example that consists of 16 vertices and 32 edges. We

Plate clutch for warpage : Place plate clutch on surface plate and check for warpage. Ensure that 0.20 mm feeler gauge does not slide freely.
The second stage of the design process is to evaluate the oxygen requirement for the organism. This is necessary so that we can establish if the vessel we construct will be capable
