Used extensively to
create 3D models of new devices and structures in the engineering, construction and manufacturing sectors, 3D modelling software uses a range of different approaches, including polygonal and
Polygonal or mesh modelling involves representing the surface of an object using polygons; that is, closed plane shapes bounded by three or more line segments. NURBS modelling involves
drawing two or more curves in 3D space, which are then manipulated by moving handles known as control vertices. C
ommonly used in computer-aided design, manufacturing, and engineering, NURBS modelling
offers greater flexibility and precision for creating surfaces with complex curves.
