Issue Description
In some instances, it is possible you would like to see a second set of units or simply change the way the units are viewed.
Solution
a. For autotext labels a new property with an expression, that contains the correct units needs to be created.
b. Preprogrammed labels have an option in the Label Default Settings under Symbol Label Custom Settings > General Settings to easily change units and decimals via selection.
c. Dimension as well as autotext labels units and decimals can be changed globally via the Project Preferences under Dimensions.
