A computer system for managing multiple distinct perspectives within a mixed-reality design environment loads a three-dimensional architectural model into memory. The three-dimensional architectural model is associated with a virtual coordinate system. The three-dimensional architectural model comprises at least one virtual object that is associated with an independently executable software object that comprises independent variables and functions that are specific to a particular architectural element that is represented by the at least one virtual object. The computer system associates the virtual coordinate system with a physical coordinate system within a real-world environment. The computer system transmits to each device of multiple different devices rendering information. The rendering information comprises three-dimensional image data for rendering the three-dimensional architectural model and coordinate information that maps the virtual coordinate system to the physical coordinate system.
