NURBS NonUniform Rational BSplines are a popular mathematical tool used in surface modelling offering excellent control over the shape and smoothness of surfaces Parametric Modelling This powerful technique allows designers to define objects using parameters or variables By changing these parameters designers can easily explore different design variations without having to rebuild the entire model from scratch Imagine adjusting the size shape and position of different components of a chair simply by changing numerical values this is the power of parametric modelling Anecdote The Genesis of a Complex Design Remember the story of the architect struggling to visualize a complex building design By 3 using sophisticated parametric modelling tools they can define the buildings form using
