NX Expressions: Simple Requirement Checks on a Measure

I got a question about using Requirement Checks with a measurement, and thought this simple example might help explain the basics. In a nutshell, an associative Measure will create an Expression containing the measurement value, and this Expression can be automatically checked against a Requirement whenever the NX model updates.
One Requirement can be checked against any number of Expressions, and any number of checks can be performed against a given Expression. In this example, I'll create one Expression driven by a Measure feature, and check this one Expression against two different Requirements -- one at a "Warning" level, and one at a more severe "Failure" level.
Please let me know if you find this useful!

Thanks for this! How do you associate these to requirements that you create in Teamcenter?
