BAS-Relief Model from Photograph for CNC

Would like to turn a photograph in to a simple BAS-relief model. (please see examples) The photograph is of a person and will be in the exact pose for the relief model. This project is for one picture, we have about 15-20 different characters ranging from Jazz players to Exotic Dancers. The typical figure size will be 6ft (2m) tall and have a depth of 3" to 4"Additional Project Description: - This is a very simple model which will be used for CNC. - No texturing or rendering needed. - "Solidworks compatible" would be very useful (It doesn't have to be made in solidworks)
