Units, precision & quality

The status bar owns units, decimal display, tessellation quality and the interface language.

The status bar (bottom of the window) holds the document-wide settings:

Units — the unit system; dimensions you type and read are in millimetres by default (MMGS: mm · gram · second).
Decimal places — display rounding only. 2 dp shows 12.70; the model keeps the exact value underneath, so nothing drifts.
Quality — tessellation fineness for the display mesh. Fine looks smooth but costs frame rate on huge models; the B-rep geometry itself is always exact, and STL export quality follows this setting (Saving, opening & exporting).
Language — English / Tiếng Việt, applied live across the interface and this Help Center.

Good to know

Typing a dimension always wins over display rounding — enter 12.7 and the model is 12.7, even at 1 dp.
If edges look faceted, raise Quality — the model is not "low-poly", only its preview.
Mass properties report in grams / mm³ with the assigned material (Viewing, section & measure).
