According to an example, an apparatus may include a hardware processor that is to access a first scanned image, in which the first scanned image corresponds to a scanned first feature of a three-dimensional (3D) object, perform a search for models matching the 3D object based upon the first scanned image, identify, from the search, a first set of candidate models, identify, from the first set of candidate models, a general identity of the 3D object, determine, based upon the identified general identity of the 3D object, a second feature of the 3D object that is to be scanned, and output an instruction to obtain a second scanned image of the determined second feature of the 3D object.
