Sweptfitting

Sweptfitting is a term used in 3D modeling and computer-aided design (CAD) to describe a specific method of creating a 3D shape. It involves taking a 2D profile, known as a sketch or cross-section, and moving it along a defined path, also known as a guide curve. The resulting 3D object is essentially a "sweep" of the profile as it travels along the path.

The profile can be any 2D shape, such as a circle, square, irregular curve, or even a complex sketch. The path can be a straight line, an arc, a spline, or any other curve. The software then generates the 3D geometry by interpolating between the profile's position and orientation at various points along the path. This process effectively "sweeps" the profile through space.

Sweptfitting is a powerful technique for creating a wide variety of shapes. It is commonly used to model objects like pipes, hoses, railings, and handles, where a consistent cross-section is extruded along a curved or complex path. The complexity of the resulting shape is determined by the complexity of both the profile and the path. Variations of sweptfitting exist, such as swept boss/base, which adds material, and swept cut, which removes material. The orientation of the profile as it moves along the path can also be controlled, allowing for more intricate designs and twists.
