In SolidWorks, surfaces are used to create complex and freeform shapes that are difficult to achieve using traditional solid modeling techniques. Surfaces are often used in product design, such as for automotive, aerospace, and consumer products, where intricate geometries are required. Key Concepts in SolidWorks Surface Modeling: 1. Surface Features: Extrude Surface: Creates a surface by extruding a sketch along a straight path. Revolve Surface: Generates a surface by revolving a sketch around
