Kathie,
If this is not a dimple then look in the help file under Sweep.
Profile and Path
• Profile . Sets the sketch profile (section) used to create the sweep. Select the profile sketch in the graphics area or FeatureManager design tree. The profile must be closed for a base or boss sweep feature. The profile may be open or closed for a surface sweep feature.
• Path . Sets the path along which the profile sweeps. Select the path sketch in the graphics area or FeatureManager design tree. The path can be open or closed, and can be a set of sketched curves contained in one sketch, a curve, or a set of model edges. The start point of the path must lie on the plane of the profile.
