You can remove top level assembly edits applied to nested assemblyReference nodes and nodes contained by Scene representations in the current scene. If the scene is saved, edits made prior to saving can still be removed.
Edits displayed in the List Assembly Edits window as Non-Removable cannot be removed from the current scene. You must open the source file containing the assemblyReference node or Scene representation to remove these edits. See Non-Removable Edits.
To remove Scene Assembly edits
If the edits you want to remove do not appear, change the Show options. See List Scene Assembly edits.
