ABOUT THIS TOOL
How Tolerance Stackup Tool fits into the workflow.
Add nominal dimensions and bilateral tolerance values to calculate the total nominal size and the worst-case plus and minus limits.
Where This Output Fits
Use it for assembly stack checks, inspection planning, and drawing review.
What to Check Before Using It
Using one-sided tolerance values as if they were bilateral, changing signs without documenting the stack direction, or ignoring datum relationships.
ENGINEERING METHOD
How Tolerance Stackup Tool generates its output.
METHODNominal total = sum of nominal dimensions. Worst-case tolerance = sum of absolute individual tolerances.
