Description

The Define function allows you to define the properties of a linear unit of measure. Use the metersPerUnit parameter to define how many meters comprise one unit.

[C#]

    private ILinearUnit DefineLinearUnit()
    {
        //Query interface for LinearUnitEdit
        ILinearUnitEdit linearUnitEdit = new LinearUnitClass();

        //Define the properties for the linear unit
        object name = "Meter";
        object alias = "Meter";
        object abbreviation = "M";
        object remarks = "Meter is the linear unit";
        object metersPerUnit = 1;
        linearUnitEdit.Define(ref name, ref alias, ref abbreviation, ref remarks, ref metersPerUnit);

        return linearUnitEdit as ILinearUnit;
    }
