PROBLEM TO BE SOLVED: To help a user to effectively use all available information and set a nominal profile constituting a profile space and its variations. SOLUTION: This method includes importing an image 42 of an object and superimposing on this image, either by hand or automatically, an estimated profile 20. The estimated profile is defined mathematically and adjusts 40 a handle 30 segment by segments, in order to match with the image. Alternatively or additionally, the user may trace (or free-draw) the profile of a known image and subsequently map a shape-definer of mathematical functions, such as a polynomial equation, a spline or a vector onto the estimated profile, in order to obtain a profile and one or more variables of that profile that can be used to reconstruct the profile of an unknown object from its diffraction pattern.
