A data model of a modeled environment is maintained within a database. The data model includes data defining a plurality of hierarchically arranged subsets of space within the modeled environment and data defining a plurality of items populating the modeled environment. In response to a first user input selecting a plurality of features of the modeled environment, where each of the selected features is one of the subsets of space or one of the items, a plurality of graphical elements are displayed within a whiteboard window to represent the plurality of user selected features. A control for at least one function is also presented to the user in association with the whiteboard window. In response to a second user input selecting the control for the function, a logical connection between at least two of the plurality of features having corresponding graphical elements within whiteboard window are automatically generated by reference to a rule set. In addition, a graphical element representing the logical connection is displayed within the whiteboard window.
