Deliberate limits

What this screening tool does not decide

  • Datum feature shift or datum mobility
  • Composite or multiple-segment position
  • Projected tolerance zones or pattern requirements
  • Actual mating envelope and Rule #1 evaluation
  • Measurement strategy, sampling, or uncertainty
  • Differences between ASME and ISO defaults beyond this shared numeric model
