A method for generating an orthotic device is disclosed. In one implementation, the method includes generating CAD model data corresponding to an orthotic device to be applied to a body part of a patient. A pattern is mapped to a surface defined by the CAD model data to produce modified CAD model data, the mapped pattern defining a plurality of perforations formed at least partially through the surface. The modified CAD model data is transmitted to a three-dimensional printer. The three-dimensional printer is to produce the orthotic device having the plurality of perforations.
