What type of project elements can be copied using the Insert views from file feature?

The feature "Insert views from file" in Revit allows users to bring in specific views from other Revit files into the current project. This capability is particularly beneficial for incorporating views that include detail elements, which can encompass annotations, tags, and other graphical representations that are crucial for conveying information effectively in a project.

Detail elements often include lines, fills, symbols, or other similar components that are integral to drafting and detailing design aspects in Revit. By utilizing this function, users can maintain consistency in detailing across multiple projects or phases of a project without the need to recreate those details from scratch.

While view templates, 3D models, and lighting fixtures may serve essential roles in a Revit project, they are not intended to be transferred through the "Insert views from file" feature. View templates are typically managed separately to set the graphical representation of views. 3D models are usually linked or imported under different functionalities, and lighting fixtures are placed as part of the modeling process rather than viewed as stand-alone elements during the insertion of views. Hence, detail elements stand out as the relevant choice for this feature.
