A method and a system for modifying a three-dimensional (3D) model to create a modified 3D model efficiently and accurately. The method includes obtaining the 3D model and identifying a first point that is a plantar head of 1. metatarsal, a second point that is a plantar head of 5. metatarsal, a third point that is a pternion, and an Achilles tendon center of coronal axis. Furthermore, defining a first straight line, a second straight line perpendicular to the first straight line and a third straight line that is perpendicular to the plane. Thereafter creating the modified 3D model by rotating and translating the heel part such that the second straight line passes through the third point (306), and the Achilles tendon is parallel to the third straight line.

A roughing system includes a roughing machine and an imaging apparatus. The roughing machine roughs an upper of a shoe along a path to form a rough trace thereon. The imaging apparatus includes a camera module and a processing module. The camera module is moved parallel to the path and repeatedly captures an image of a portion of the upper having a segment of the rough trace thereon each time when one of a first condition that the camera module has been moved by a predetermined length and a second condition that the camera module has been moved for a predetermined time duration is satisfied. The processing module receives the images respectively of different portions of the upper that are sequentially captured by the camera module, and is configured to generate a panoramic image based on the images.
