host for the pick lines. This gives you much more flexibility, especially if the
host is parametrically driven.
After creating the path for the sweep, you must click the green check mark
button to exit sketch mode for the path. This returns you to sketch mode
for the sweep geometry. With the path drawn, an origin and workplane
indicator for the sketch profile location is shown on the path, as seen in
Figure 17.9
. The profile location indicator can be moved anywhere along the
path while you're sketching the path by selecting the indicator and dragging
it to the required location. This allows you to locate the profile parallel to
a view plane, this will make sketching the profile easier. This is especially
useful when creating paths that contain arcs because the profile may end
up in the middle of an arc, at an angle that would be difficult to draw. The
location of the profile plane will not have any effect on predefined profile
families. For curved sweeps that do not display the profile in a regular view,
it can be easier to sketch a small, straight segment prior to the curve. This

the profile is created, you can go back and delete the straight section of the
path.
