One or more embodiments of the invention enable a method, apparatus, article of manufacture, and data structure for an adaptable multi-representation building systems data structure in an application program. The data structure comprises a single object that can represent a real world component used throughout a building life cycle, from preliminary design throughout a life of the building. As design decisions are made, the single object can acquire further definition, gaining one or more characteristics that characterize and specify the real-world component. The single object and a connector of the object can recognize and automatically connect to a valid subsystem. Further, the single object can represent itself in multiple graphical and non-graphical displays.

One or more embodiments of the invention provide a visual cue for placing a first geometric entity in a three-dimensional space represented in a computer-implemented graphics program. A two-dimensional viewport of 3D space is displayed on a display device. The operator selects a first point within the two-dimensional viewport. Based on the first point, a visual cue is displayed in the two-dimensional viewport that indicates a coordinate system plane within the three-dimensional space. The coordinate system plane identifies a plane where the first geometric entity is to be placed. Using the visual cue, a second point is selected on the coordinate system plane in the two-dimensional viewport. Thereafter, the first geometric entity is placed on the coordinate system plane based on the second point.
