The design model is drawn to actual size. A design model can be a 2D or a 3D model.

Level Display dialog in MicroStation is used to turn on and turn off levels in a model. This dialog contains the display control options (on/off switches): View Display, Global Display and Global Freeze as shown in below image.

Global Freeze Changes in the level display affect all views in all models in the open file. When Global Freeze is on, elements on...
