Remove XRef Record Deletes the highlighted XRef record(s) after you confirm the action. All entities associated with the highlighted record(s) are removed from the scene. NOTE Once you have removed an XRef record, you cannot undo this action. Combine XRef Records Click to combine the contents of more than one XRef record from the same source file into one record. This is useful when you want to clean up the organization of your XRef records. Rather than having multiple records of the same file, you can group all of the objects, controllers, and materials from that file under the same record. This button is available only when you highlight two records that refer to the same file name and path; both records must have identical settings. XRef records must refer to the same file with the same XRef entities. Combine XRef Records only allows you to consolidate all of the entities of one file into one XRef record entry. It does not allow you to combine the contents of different files, even if the files have the same name. NOTE Nested externally referenced records cannot be combined. Update Refreshes the contents of the selected XRef record. If the objects, controllers, materials, or manipulators referenced have changed in the source scene, you will see these changes in your master scene. NOTE The changes must be saved in the source file before you see them in the master file. If you remove externally referenced entities from the master file using the Delete XRef Entity button, these entities will not be externally referenced when you update the XRef record, even though they continue to exist in the source scene. NOTE Reloading XRef items works correctly even when an object in the source scene has been renamed, or deleted and then re-created with the exact same name, including character case. However, if the source scene contains several nodes with the same name, an XRef item corresponding to a node whose name is not unique in the source scene might not necessarily resolve as you expect during the update process. For best results, maintain unique names for all nodes in the source scene. External References (XRefs) | 6943
