A system, computer-readable storage medium storing at least one program, and a computer-implemented method for providing three-dimensional operations in an isometric projection are presented. A graphical user interface may be presented to a user that presents an isometric projection of a virtual environment. A placement event corresponding to a user initiating a placement of a game object within the virtual environment may then be detected. The game object may be modeled with a two-dimensional model. Selection coordinates associated with the placement event are then obtained. Using the selection coordinates, it may be determined that the user selected one of a plurality of surface areas of an existing game object. Then, the game object is then inserted within the virtual environment relative to the one of the plurality of surface areas of the existing game object.
