Units of Measure

The inclusion of a much wider range of units means that most real attributes now have a default unit (usually in SI units) for storage and input/output. User can also set a default unit, which must be of an appropriate type, for input and output. Input via the command line or GUI also allows the user to specify an alternative unit.

This does mean some unavoidable changes to the command line so user applications using real attributes will need to be reviewed. There are also minor changes to many of the user interface forms. The new functions can also be accessed by the .NET Units interface, as detailed in the .NET Customisation manual.

Customers who have written or adapted PML applications may need to check these. They are explained in more detail in the 12.0 to 12.1 Upgrade manual.

Several of the reference manuals have been updated to reflect these changes, including:
