Detail Components invisible in Drafting View

[Anonymous]

Recently, my drafting view is not allowing me to see a certain detail component. When I Reveal Hidden Elements, the detail component shows up as if it is not hidden, but when I turn off the temporary mode, it disappears again. Any thoughts?

- Do the detail components have CAD entities?  If so, check Imports category visibility > Imports in Family.

- Does the view have View filter?
