The Units page lets you specify 3D measurement units.

You can define units for all display parameters: length, angle, area, volume, and distance type (dimensions). You can also modify the interpretation of units of CAD models.

This page discusses:


The tabs on the Units page let you choose which 3D measurement units you want to define.

  • All 2D measurements (such as border widths and 2D panel positions) are in millimeters.
  • Input and output units do not affect conversions from CAD to Composer format. Composer internal units are millimeters.

LengthLets you define length measurement units.
AngleLets you define angle measurement units.
AreaLets you define area measurement units.
VolumeLets you define volume measurement units.


The Output section lets you define the output parameters for the chosen measurement unit.

Command NameDescription
Length / Angle / Area / Volume Specifies the display units.
Number of decimals Specifies the number of places displayed after the decimal point for floating-point values in the viewport. To specify the number of decimals for floating-point values in the Properties pane, set PropertiesValueNbOfDecimal on the Application Preferences - Advanced Settings page. See Advanced Settings.
Decimal symbol Specifies the decimal point character:
  • . (period)
  • , (comma)
  • ; (semicolon)
Show units Specifies how units are displayed in measurements:
  • Short - Displays unit abbreviations (example: 15.1 cm).
  • Long - Displays full unit names (example: 15.1 Centimeters).
  • None - Displays no units (example: 15.1)


The Input section lets you define the input parameters for the chosen measurement unit.

Command NameDescription
Model unit (internal) Specifies internal model units. For example, change internal units if the CAD units are centimeters instead of the Composer default units of millimeters.
Important: For SOLIDWORKS files, Model unit must be millimeters.
