The purpose of hosted families in Revit is to require a host element, such as a wall, floor, or roof, in order to exist within the model. This relationship ensures that the hosted family takes on the properties and characteristics of its host, allowing it to inherit parameters such as material, location, and alignment. For example, when you place a door family, it is hosted by a wall. If the wall is modified, the door adjusts accordingly, maintaining its position and relationship to the wall.

Hosted families help to create a more accurate representation of how components interact within the built environment and ensure that elements are appropriately aligned and constrained to their surroundings. This is particularly useful in complex projects where the spatial relationship between different elements is crucial for accurate modeling and documentation.

In contrast, independent elements do not depend on any other components, and while some families may be used primarily for 3D modeling, this is not their exclusive purpose. Similarly, custom detailing can be done with both hosted and non-hosted families, so it is not a defining purpose of hosted families.
