Choose units and measurement precision
Use metric or imperial measurements without changing the shape of existing objects.
Unit preference is a project setting, separate from interface language and regional number formatting. Changing display units does not move or resize existing geometry.
Select the project unit system
Open Settings from the Sections menu. In the Project scope, open Units & formatting, then choose Metric (m, cm, mm) or Imperial (ft, in) in Unit System. The page also contains Currency and Regional format; regional format does not change the interface language.
Set display precision
For length, area and volume precision, open Canvas & drawing settings → General and expand Display Precision. Metric precision uses decimal places; imperial precision uses inch fractions. These are display settings, not a request to round the stored geometry.
Check units while entering a value
In measurement inputs that support unit expressions, include a suffix when needed: for example 5 ft or 150 cm. Bare values follow the current input’s displayed unit. Do not assume every plain numeric field accepts a measurement expression.
Choose units before creating a project
The New Project dialog offers Metric and Imperial, with a detected starting preference. Check the displayed dimensions and grid spacing after switching. Existing drawing measurements remain the same physical size when changing units later.
