The concept of a model hierarchy in Building Information Modeling (BIM) refers to the structured organization of all the components and information layers within a BIM project. This hierarchical structure is essential for managing the complexity of construction projects, which can involve vast amounts of data related to the building's design, construction, and operation phases. The model hierarchy helps in organizing this data in a way that is both logical and accessible to all stakeholders involved in the project.

Selecting elements from a BIM hierarchy involves navigating through the structured layers of data to pinpoint specific components or assemblies. Users can use this to navigate through a typical hierarchy such as building>floor>room>discpline for example. For instance, a user might start at the project level, narrow down to the discipline of interest, like electrical systems, and then drill down further to select specific systems or components, such as lighting fixtures or wiring.

Users can also use the hierarchy to toggle on and off model visibility, or to set a opacity range that will make that model transparent between 0-100%, this is useful to be able to for example make the outer envelope of a building transparent to see the detail inside.

Tobe Builder provides a flexible and customizable approach to organizing BIM (Building Information Modeling) data. It allows users to create custom hierarchies based on any metadata contained within the BIM model, enabling the creation of unique structures tailored to specific needs or workflows.

This the custom hierarchy supports dynamic reordering of the BIM hierarchy, allowing users to adjust the organization of model data for different project phases or stakeholder requirements.

Tobe Builder also allows users to toggle terrain cutting on and off. If toggled on Tobe Builder calculates the outline of a BIM model/object in plan (X,Y) and clips that area from the GIS basemap or scene layers. This is useful for example as it allows users to have the foundation of a building cut away the ground layers allowing users to see the subterranean levels of a project.
