AutoCAD TILEMODE 0 and 1

MicroStation uses design models and sheet models for geometry and documentation (File > Models). The DGN file format allows an unlimited number of design and sheet models into which data can be inserted as cells (blocks), references, or original geometry and annotations. New models can also be designated as cells, and thus can be inserted into other drawings and models as needed. To navigate between models, use the View Groups window docked at the lower left corner of the application window. A new view group is created by default with each new model.

For more information, see Models.
