Stores the current 3D Studio MAX scene and its settings in a restorable buffer.
Hold saves the scene to a temporary file (maxhold.mx) under the directory specified as the Scenes path in the Configure path dialog. The Fetch command restores the contents of the Hold buffer, which includes all geometry, lights, cameras, viewport configuration, and selection sets.
Use Hold before you undertake an operation that may not work as expected. These commands allow you to easily get back to a particular point if you need to.
