PLANE SURFACE MODELLING

Plane Surface Modelling is a computer-aided design (CAD) technique used to create and represent flat, two-dimensional surfaces in a three-dimensional environment. This method is commonly applied in engineering, product design, manufacturing, and architectural modeling to define simple geometric shapes and serve as a foundation for more complex surface and solid models. In the modeling process, a plane surface is generated by connecting edges, lines, or boundary curves to form a flat area with no curvature. Plane surfaces are essential for creating basic structural components, defining reference planes, and constructing accurate geometric models. They also play an important role in computer-aided manufacturing (CAM) and simulation analyses, where precise surface definitions are required. The use of plane surface modelling improves design accuracy, simplifies the modeling process, and provides a clear representation of flat features before further modifications such as extrusion, lofting, or surface blending are performed. As a result, it is a fundamental technique in modern CAD systems and engineering design workflows.
