Engineering Shape-Searching
3DESS, an Engineering Shape Search System, is a research project being undertaken by researchers at Purdue University. The goal is to develop a search mechanism for engineering parts that will retrieve similar 3D models based on their shape.

The aim is to reduce the amount of time taken to find data that is available but is difficult to retreive using traditional approaches, such as searching by model name etc.
A demonstration prototype system, ShapeLab, is available =. This enables a user to select a part that resembles a required part and to retrieve similar items, or they can sketch a part as a starting point.

Similar research work is being undertaken in a number of places including the Princeton Shape Retrieval and Analysis group at Princeton
