# Management of Sheathing, Stud Layers, and Division Library Elements Claddings can be used as reference claddings. If they are deleted, the reference cladding will be missing in the respective setting. Therefore, deletion of claddings that are registered as reference claddings is locked. A message appears with the numbers of the settings that refer to the cladding to be deleted. The order of the settings can be changed. To do this, simply drag the setting in the tree to the new position while holding down the left mouse button. * The settings are renumbered; as a rule, several settings will receive a new number. * For all claddings used as reference claddings, the number in the references is reorganized. If the cladding previously had number 2 and now has number 5, the 2 will be replaced by 5 in all reference claddings as well; the reference to the correct cladding is thus preserved. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
