First, pick a single feature that you want to machine on the part.
Figure out if it is actually a wrapped feature. Some features may appear to be wrapped, but aren't. If the feature has all straight sides, then it can be cut with a normal 2.5D feature.
Consider the restrictions of 4th axis wrapping to make sure it is appropriate for cutting the feature.
Do the sides go through the center axis of wrapping? If you really need to cut these sides accurately, you will need to use Cut sides perpendicular to index axis.
Use surface edges to extract a curve from the solid model.
Unwrap the curve. Make sure you use the option to project to the UCS. The curve may look strange to you, but it will work.
Make the feature opting to wrap around the index axis. Note that this option is not available in the feature wizard. If you use the wizard, you must create a normal features and edit it to change it into a wrapped feature.
Generate the toolpaths. If you have any problems consider the restrictions of 4th axis wrapping.
