The extruded surface should look like this.
2 For more practice, choose Extrude again. Select the spline and then a location
on the line to determine the length and direction.
Because the line is obscured by the first surface you created, you may have
difficulty selecting it. Press
CTRL as you select, to cycle through the objects.
Press
ENTER when the line is highlighted.
3 Use the Zoom Extents option of
ZOOM to redisplay all the wireframes and
select the object for the next exercise.
Swept Surfaces
A swept surface is a wire cross section moved along a curved line called a rail.
You can use multiple cross sections and one or two rails. The lines on the
swept surface in the illustration are U and V display lines. Cross sections can
be dissimilar but you need to select them in order.
In this exercise, you use different combinations of cross sections and rails to
create four swept surfaces.
