Linear Sweep
In linear sweep, the path is a linear or circular vector described by a linear, most often parametric. Linear sweep can be divided into translational and rotational sweep. In translational sweep, a planar two-dimensional point set described by its boundary (or contour) can be moved a given distance in space in a perpendicular direction (called the directrix) to the plane of the set. For rotational sweep, the planar two-dimensional point set is rotated about the axis of rotation by a given angle
