A multi-purpose layout tool has an elongated main body component and a slide block component. Each component is designed to be used separately or in combination to perform a multitude of functions. An elongated opening extends substantially the length of the main body. The opening is configured to accept a slide block guide member extending from the slide block, which is secured within the opening by a threaded knob. The slide block can be adjustably secured within the opening, at designated angles in relation to the main body. The slide block also has a number of features, including dual level members and a compass pin which is used in conjunction with the main body for circular measurement, layout, and marking.
