Starting with simple, basic lines and polylines, you learned the importance of using object snaps and point filters to ensure accuracy in 3D space. You learned that many of the editing operations you use in 2D, such as MOVE and ROTATE, have equivalent 3D commands. Finally, you learned about a special 3D object called a region.
