Sweep Representations

Solid modeling packages often provide a number of construction techniques. A good example is a sweep, which involves specifying a 2D shape and a “sweep” that moves the shape through a region of space.

Exemple : rotation around an axis, but it could be along any path

Example of torus designed using a rotational sweep. The periodic spline cross section is rotated about an axis of rotation specified in the plane of the cross section.

We perform a sweep by moving the shape along a path. At intervals along this path, we replicate the shape and draw a set of connectiong line in the direction of the sweep to obtain the wireframe reprensentation.
