Abstract
As a new product development as well as digestion and absorption of advanced technology an important tool, reverse engineering and rapid prototyping technology capable absorb imported technology-based requirements.Their emergence has changed the traditional product design and development model, greatly reducing product development cycle time, improve product development success rates.
Today, every industry increasingly focused on product design in order to attract customers and ultimately commercial success.This design in consumer products especially embodied.Especially mobile phones, digital cameras, car and other industries.Reverse engineering is to design the car door is an example of its characteristics and its importance. Key word：reverse engineering rapid prototyping technology
vehicle door
