In this lesson, you will expand your program so it actually draws something within AutoCAD—the polyline outline of the garden path. To draw the border, you must create some utility functions that are not specific to a single application but are general in nature and may be recycled for later use. You will also learn about writing functions that accept arguments—data that is passed to the function from the outside—and why the use of arguments is a powerful programming concept. By the end of the lesson, you will draw an AutoCAD shape parametrically, which means dynamically drawing a shape based on the unique data parameters provided by the user.
