Lock-It – Password Protect Elements and Views

From the Autodesk App Store:

With LOCK-IT, you can lock items and views with a security password. These items will not be allowed to be modified or erase by any mean. LOCK-IT is stronger than the PIN tool.

Keep your model safe from "accidents", deleted views or elements, modifications not approved, changes in standard elements, grids moved, levels moved or renamed.

Using LOCK-IT, you can set a PASSWORD to protect any element in the model from unwanted changes or even from being deleted by "accident".
