Paragraph Number

181

Generation of the contours of the cuneiform apposition portion 342 and the metatarsus apposition portion 344 of the selected template cutting guide model 1834 may be performed relative easily in various CAD programs. In some embodiments, the shapes of the corresponding surfaces of the first cuneiform 210 and the first metatarsus 230 may be obtained directly from the bone model 1804, anatomic data 1812, CAD models and/or CT scan data, and simply copied onto the selected template cutting guide model 1834. 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 of the selected template cutting guide model 1834 with a shape that matches the surfaces of the first cuneiform 210 and the first metatarsus 230.
