A system and method are provided for automatically defining acceptable shape requirements for an object. A reference shape is a shape that the object should be in, and the acceptable shape requirements define an acceptable shape of the object that may deviate from the reference shape and yet is acceptable to a user. The system includes two elements: a processor, and a scanner coupled to the processor for scanning objects and sending scanned information of the objects to the processor. The processor is configured to perform three steps: (i) receiving scanned information of two or more acceptable shapes from the scanner; (ii) combining the scanned information of the two or more acceptable shapes to define acceptable shape requirements; and (iii) storing the acceptable shape requirements. The processor may be further configured to perform the steps of: (iv) receiving a scanned shape of an object from the scanner, and (v) determining whether the scanned shape of the object is in conformance to the acceptable shape requirements.
