When Sweeps is selected from the Create>Swept Menu, the Extrude Planar Profile dialog box is displayed. Contained in this dialog box are several settings that allow you to specify how exactly an extrusion is to be created. The segment below will discuss the several options available to you from the dialog box.
Chose an end method, or, how the extrusion end is to be defined.
Midplane extrusion, when enabled, allows the profile to be extruded by half the distance in both directions when extruding by length OR by the profile-position distance when extruding to a position. When extruding by mid plane there is no prompt to select the extrude direction. If a draft angle is also specified, an equal draft is applied in each direction. The length of the extrusion is entered in the Distance box.
Indicate a direction vector for the extrusion being created.
The options in the Draft Properties section allow you to shrink or expand the profile curve as it is extruded.

While a profile is being extruded, Twist angle allows for the profile to be twisted by a given angle.
