Elements are meant for typical conditions in the project and also are useful for miscellaneous project resources whose external referencing (xref) behavior you wish to control manually (not appearing automatically in views or sheets).
This element is intended for creating toilet room layouts that will occur more than once in the project. Rather than draw the same layout several times, or copy and paste it, only to have to redraw when changes occur, use an element to centralize edits to a single source file.
This element file contains a simple rectangle on a non-plotting layer as a way to alert you to its presence in the preconfigured files. Open this element and delete this rectangle and replace it with your actual toilet room geometry at the start of a project. The Typical Toilet Room Element is referenced into the various core constructs.
