Duplication is a process of making a copy of a copy of an existing object. To obtain a drawing of this object, the profile of the object has to be determined, followed by manual drawing to produce the drawing. Thus, this thesis presents a method that can help to automate the process of part drawing with the help of a vision system. The approach is useful and the time required to do shape detection of an arbitrary profile of an object can be reduced. By using the approach of a vision assisted automated CAD drawing, the tedious task of this process can be done easily. In the developed prototype system, the object which its drawing is to be produced automatically, is placed under the camera frame of a vision acquisition system and the image of the object is acquired. Later, an image processing module performs the necessary image manipulation to obtain the information regarding the object in the acquired image. This information is used by the automatic drawing module to produce the drawing of the object automatically. Finally, the 2D drawing of the object is drawn automatically.
