Eighteen months ago, I was writing that shape searching could become a reality. Now, the researchers at Purdue University who developed this initial system are providing benchmarking tools to evaluate how well their search system is working. Even if these tools are designed for computer-aided design (CAD) engineers, you're welcome to use the Purdue benchmarking system for free. Its database contains about 1,000 parts grouped in 40 categories. You select a part, such as tha backdoor of a car, and you can see how well the system can find other 3-D objects with similar shapes in the database. The idea of searching parts in a manufacturer database was born from the frustration of CAD users who routinely spend up to 80 percent of their time searching for information stored in the computers of their companies and trying to reuse it.
