Claim:
1. A method of assessing a prosthetic socket shape for receiving a residual limb of a patient, the method comprising: calculating surface normal angle errors between points on a first digital model and corresponding points on a second digital model, the first digital model corresponding to the prosthetic socket shape and the second digital model corresponding to a desired shape; plotting the calculated surface normal angle errors to a surface model; and displaying the plotted surface normal angle errors to an operator; accepting or rejecting the prosthetic socket shape in response to the plotted surface normal angle errors; calculating an average radial difference between points on the first digital model and corresponding points on the second digital model and determining whether the mean radial error is above or below a set threshold; wherein the set threshold has a value between 0.24 mm and 0.29 mm.
