Other than in the sense that certain aspects of a model can be "recognized" by some of the NC functions as if they were "features", there is no general purpose "Feature Recognition" function in NX.
What you can do is to open/import the non-feature model into NX and using the Direct Modeling tools, add constraints, such as a diameter to a hole or a radius to a blend or a distance between 2 faces, creating for all intents and purposes, a parametric constraint scheme that will allow you to edit the size of a solid model AS IF IT WERE a feature-based model. Note that these constraints would be created as features, but they would not necessarily look anything like the feature graph of a model built from scratch as features.
