## Abstract

A method for generating an orthotic device is disclosed. The method includes receiving data from a client device of a patient, the data comprising patient information and image data representative of a body part of the patient. The method further includes generating, based on the image data, three-dimensional model data representative of the body part, and generating parametric CAD model data of the orthotic device based on the three-dimensional model data and the patient information. The parametric CAD model data is transmitted to a three-dimensional printer, wherein the three-dimensional printer is to generate the orthotic device based on the parametric CAD model data.
