When creating a boundary with 'boundary drive method' for a multi mill axis variable contour operation.
The boundary can be defined using curves / edges, but when attempting to define a plane the model geometry is not selectable.
Solution
Workaround is to create a Wave link of the part body. It is then possible to select the geometry and so define the plane in the same way as in NX 11.
