In-Depth Information
In step 3 of the previous exercise, you may have noticed some command-line options. These
options offer additional control over the way Sweep works. Here is a rundown on how they work:
Alignment
This option lets you determine whether the object to sweep is automatically set
perpendicular to the sweep path. By default, this option is set to Yes, which means the object
to sweep is set perpendicular to the path. If set to No, Sweep assumes the current angle of the
object, as shown in Figure 20.45.

Alignment lets
you set the angle
between the object
to sweep and the
sweep path.
Rotate the object to sweep to an angle away from
the WCS, and then turn off the Alignment option.
By default,
the object
to sweep
is aligned
perpendicular
to the sweep path.
You can skew
the object to
sweep in relation
to the sweep
path by using the
Alignment option.
Base point
By default, Sweep uses the center of the object to sweep as the location to align
with the path, as shown in Figure 20.46. Base Point lets you set a specific location on the object.

Using the Base
Point option
By default, the center of the
object to sweep is aligned
with the sweep path.
With the Base Point option, you can
select a location on the object to sweep
that will align with the sweep path.

Scale
You can have Sweep scale the sweep object from one end of the path to the other to
create a tapered shape, as shown in Figure 20.47. This option requires a numeric scale value.
