The available options for selection resolution are as follows:
- File. Makes the object path start at the file level; as a result, all objects at the current file level are selected.
- Layer. Makes the object path start at the layer node; as a result all objects within a layer are selected.
- First Object. Makes the object path start at the highest level of objects below the layer node, if applicable.
- Last Object. Makes the object path start at the lowest level of objects in the Selection Tree. Autodesk Navisworks looks for composite objects first, and if none are found, the geometry level is used instead. This is the default option.
- Last Unique. Makes the object path start at the first unique level of objects (not multiple-instanced) in the Selection Tree.
- Geometry. Makes the object path start from the geometry level in the Selection Tree.
