In this paper, we present the way to obtain in AutoCAD the solids that materialize the worm and wheel gears. The worm and wheel gears are practically used first of all due to their high transmission ratio. After the state of the art of the worm and wheel gears, we present the manufacturing possibilities of the wheels. Further on, one presents the way to obtain of the solids that materialize the cylindrical and globoid worms, using AutoLisp functions in AutoCAD. By Boolean operations, one extracts from the raw material that approximates the worm, the solid that materializes the tool. One thus generates cylindrical worms with 1, 2, and 3 starts and globoid worms with one start. The obtaining of the wheels is performed in a similar way, the tool being the already obtained worm.
