In this research, by using an input device (keyboard, mouse) information may be transferred into the computer and drawings created in the Auto CAD can be edited using natural language. A system has been developed to generate mechanical objects, from basic primary drawings such as circle, arc, and line. Drawing commands are given in linguistic form and edit tool commands are given by using function keys from the keyboard or from the shortcut menu. The edit tools are fillet, chamfer, and trim. This project has the ability to magnify the image for better viewing. In this project a new technique has been introduced to select an object. Each object has been given a unique numerical name, thus allowing the object to be selected as many times as the name is chosen. The main goal of this project is to create a simple and easier way to draw objects without using a mouse. This will allow a physically disabled person or a person who is unable to use a mouse to draw a basic drawing by using a keyboard. This process is much more interactive and user friendly. The developed software can calculate intersection points and can write and read DXF files, which can be read by AutoCAD. After reading the DXF file it can redraw it on an AutoCAD interface. This software has been developed using Visual Basic 6, as part of the proposed system. It also provides a good foundation for a software operated by natural language communication.
