A CAD model customized, which represents a mechanical design of an artifact comprising a set of parts with respective dimensions. A configuration model defines an exhaustive range of ways to customize the CAD model by changing a subset the dimensions. A model translation module is arranged to convert the configuration model into: (i) a CSP representing all possible customizations defined by the configuration model, the CSP is defined by: (a) set of integer variables, wherein each variable may attain a finite number of different values, and (b) a set of constraints restricting which variable values that are simultaneously possible for the variables, (ii) a set of CSP variable-dimension pairs, and (iii) a set of CSP variable-parameter pairs. A configuration engine is arranged to: calculate a solution to the CSP, which solution is optimal with respect to a value assigned to each variable in the CSP relative to a predefined optimizing criterion, and assign a parameter value for each CSP variable-parameter pair, the allocated parameter value corresponding to the value assigned to the CSP variable in the optimal solution. A CAD interface is arranged to assign a dimension in the CAD model for each CSP variable-dimension pair, where the assigned dimension corresponds to a value assigned to the CSP variable in the optimal solution.
