Abstract: In some embodiments, a time-based computer-simulated environment representative of a project model may be generated based on project modeling data associated with the project model, where two or more dimensions of the environment are navigable by a user via user inputs for navigating through the environment while the environment is set to automatically change in accordance with the environment's current time. An annotation for an object in the environment may be received based on user selection of the object during the presentation of the environment while the environment is set to automatically change. Natural language processing may be performed on the annotation to identify data relevant to the object, wherein the identified object-relevant data is not included in the annotation as received. The annotation may be modified to include the identified object-relevant data, and the modified annotation may be presented with the object during the presentation of the environment.

Abstract: In some embodiments, a time-based user-annotated presentation of a user-navigable project model may be provided. Project modeling data associated with a user-navigable project model may be obtained. A time-based presentation of the user-navigable project model may be generated based on the project modeling data such that the user-navigable project model is navigable by a user via user inputs for navigating through the user-navigable project model. An annotation for an object within the user-navigable project model may be received based on user selection of the object during the time-based presentation of the user-navigable project model. The annotation may be caused to be presented with the object during at least another presentation of the user-navigable project model.
