Are you thinking of PTC's Reverse Engineering eXtension (REX)? It is designed to help you generate robust, feature based geometry from scanned data. http://www.ptc.com/product/creo/reverse-engineering-extension
You posted in the Academic Program forum and REX is not currently included in the Academic Editions of Creo.
