In the context of a computer-aided design platform providing a user-specific set of acquirable objects, a CAD design and object acquisition computing system is configured for accessing a set of object properties for a particular object; analyzing object selection data indicating a set of currently placed within the CAD environment, analyzing related design data comprising a set of design data for a set of other virtual environments, wherein at least a portion of the other virtual environments in the set of other virtual environments include the particular object; accessing an object design ruleset defining one or more selection limitations; processing the set of object properties, the object selection data, the related design data, and the object design ruleset using at least one of a rules-based model or a machine-learning model to generate an object recommendation; and modifying a graphical user interface to include an indication of the object recommendation.
