A computer-implemented technique for generating a data set that geometrically defines a bone plate design is presented. A method implementation of this technique comprises visualizing, based on shape data of a bone, a bone model on a display device, deriving, responsive to a user interaction signal that is indicative of a user interaction relative to the bone model, plate design data representative of a plate-specific design property, and generating a data set that geometrically defines a bone plate design from at least the plate design data and one or more generic plate parameters.
