Options with Numeric Values
Options with numeric values expand the choice behavior to allow you to enter the value that can be used in choice rules and assignments. For example, the option Wheel_Base can have choices: 18 inch, 20 inch, 2 inch, 26 inch, 28 inch, 3 inch, 32 inch. For options without numeric values, a rule to consider all choices less than 26 inches can be as follows: Wheel_Base=18inch/20inch/24inch. If a new Wheel_Base choice of 19 inch were added to the option, some rules would need to be updated to include 19 inch.
Instead, using options with numeric values, you can create and maintain rules more efficiently by defining a numeric value for the choices. For example, for options with numeric values, the same Wheel_Base rule is Wheel_Base < 26 inch. Additionally, if a 19 inch wheel choice is added in the future, this Wheel_Base rule does not need to be modified.
Consider this information about options with numeric values:
• An option with numeric values has an additional required attribute, Quantity of Measure. For example: length, mass, and so on.
• An option with numeric values is always Single Selection.
• Choices for options with numeric values have an additional attribute Value.
Options with numeric values are identified by the
icon, and their choices by the

Choices with Values
Consider this information for choices of an option with numeric values:
• A choice of an option with numeric values has the same attributes as a textual choice, plus an additional required attribute, Value.
• A choice value can be expressed as an integer or a real number. For example, 1 or 1.1.
• All choices have the same unit of measure as the option they belong to.
Updating Options and Choices Using Windchill Load Files
You can use the Windchill loader to convert existing options and choices from string-based to those with numeric values. Using a loader, you can specify attributes that you want to define or change, including the Data Type and Value for options and choices with numeric values.
| You can also use this method to correct errors in the existing options and choices. |
