Using the sweep command, a 2D sub-object or object is swept along an open or closed path to generate a 3D surface or solid. An open-ended item is swept to generate merely a 3D surface, but an object encompassing the region is swept to make a 3D solid or surface.

In AutoCAD, the loft command is used to generate a 3D solid or surface. Within the gap between various cross sections, a 3D solid or surface is generated. The cross-sections determine the solid's or surface's exterior shape.

The loft command is similar to extrude, but it has a lot more flexibility. Instead of extruding a single shape, you can use the loft command to extrude multiple shapes into a single continuous object.

In the space between many cross sections, creates a 3D solid or surface. Loft cross sections can be open or closed, planar or non-planar, and edge subobjects. Depending on the mode, open cross sections form surfaces, whereas closed cross sections create solids or surfaces.
