Abstract
Many computer packages are commercially available to design an object. AutoCAD is one of these packages which is commonly used in educational institutions to produce and modify technical drawings using personal computers. A customized Menu is developed to control the AutoCAD drawing editor through a digitizer tablet buttons. Tablet menu assigns AutoCAD commands to different locations of the digitizer tablet surface which is divided into four rectangular areas containing different sets of macros. Each macro contains a series of AutoCAD commands and parameters put together to perform an identified task.
Tablet area one consists of 200 boxes used for blocks library applications. Over 54 block drawings of different mechanical drawings are established, when user clicks the digitizer at one of these boxes location, a selected mechanical item is inserted from the library onto the current drawing with suitable scale factors. The user can assemble mechanical components of different elements from this library within a short time and with little effort.
