The word outline has two definitions. It can be a line or a set of lines that enclose or indicate the shape of an object. It can also mean a general description or a plan giving the essential features of something but not the detail. Both of these definitions have spatial implications especially when the words enclose, object, and plan are thought of in architectural terms. For the work here, outline is used as the descriptive title of a study that relies on the simple act of placing two squares and two quarter-circles together so that their faces correspond. What results is a rich set of 32 possible combinations yielding both familiar and unfamiliar figures. Considered to be more than just an exercise in composition, this study begins to be suggestive of proto-architectural space when the resulting outlines are viewed as horizontal or vertical cuts through an object. By reading the outline as a plan or a section cut, a figure ground relationship between solid and void begins to emerge. Outline with its adherence to simplicity depicts only the essential features inviting the viewer to invent a third dimension to complete the form.
