Under the Project Settings tab, you will be able to set the standard units to be used throughout the project. Trimble Connect has expanded unit settings for the project system and allows users to specify display precision on each unit e.g. Length, Area, Volume Angle and Measurements Length. Unit setting support varies by application.
Open a project in the Trimble Connect for Windows application.
Open the Settings dialog and click the Project tab.
Select the Unit system: Imperial, Metric, or Custom.
Select the unit of measure and display precision for distance, area, volume, weight and angle.
When you are finished, click Close.
