Which type of family should you create if you want it to be available in other projects?

Creating a loadable family is the best choice if you want it to be available in other projects. Loadable families are defined in independent files that can be created and stored in the project library. Once a loadable family is created, it can be loaded into multiple projects, making it highly reusable.

Loadable families typically include components like furniture, fixtures, or other custom elements that are not specific to a single project. By utilizing loadable families, users can maintain consistency across various projects and utilize a well-organized library of components.

In contrast, system families are built-in components of Revit and cannot be shared across projects because they are inherently tied to the project type. In-place families, meanwhile, are created directly within a specific project file and are not reusable in other projects, as they are customized for that particular context. Instance refers to specific occurrences of families placed in a project and does not define a type of family that can be created for reuse.
