The Level System

In this chapter, you will find procedures used for organizing and maintaining your data in logical levels. Each level is named and stored in the DGN file. The display of elements residing on particular levels can be turned on or off, as necessary, to display only the desired information. When MicroStation users refer to turning levels on and off or toggling their display, they really mean toggling the display of elements residing on those levels.
