You can change the display of the model to show a different subdivision level and continue sculpting or editing at that level.
- Press the Page Down key to display a coarser subdivision level.
- Press Page Up to display a finer subdivision level.
The number of polygons for the model appears briefly in the Heads-Up Display in the upper right corner of the 3D View. See Heads-up Display.
Note: Each time you step up or down a level, the previous subdivision level is hidden in the 3D View.
