Why might an architectural designer be unable to select a linked Revit model?

An architectural designer may be unable to select a linked Revit model if the Select Links option is disabled. This feature is crucial because it directly affects the ability to interact with and manipulate linked models within the host Revit project. When this option is turned off, the software does not allow selections on the linked files, thereby preventing any modification or visibility of elements contained within those links.

While there are other scenarios that could complicate model interaction, such as a view template affecting visibility settings or elements being placed in a closed workset, these situations do not inherently restrict the ability to select the linked model itself. The status of another user borrowing the link can create access issues or limitations depending on the worksharing settings, but it does not directly cancel the ability to select the link as a disabled Select Links option would. Therefore, understanding the functionality and impact of selecting links is critical for efficient collaboration and model management in a Revit environment.
