Paragraph Number

71

Generation of the contours of the cuneiform apposition portion 342 and the metatarsus apposition portion 344 may be performed relative easily in various CAD programs. In some embodiments, the shapes of the corresponding dorsal surfaces of the first cuneiform 210 and the first metatarsus 230 may be obtained directly from the CAD models and/or CT scan data, and simply copied onto the model for the body 310 of the cutting guide 300. Various operations may be used to copy surfaces from one object to another. Additionally or alternatively, various Boolean operations, such as a Boolean subtraction operation, may be used to remove material from a model for the body 310 with a shape that matches the dorsal surfaces of the first cuneiform 210 and the first metatarsus 230.
