Measure & calculate
Distances, areas and angles to the drawing’s own scale, ISO fits and limits, tolerance stack-ups and heat maps, the engineer’s calculators and a mechanical check with the equations written out.
Tolerance stack-up in a minute
Pick the dimensions straight from the Inspector’s list, set the direction of each, and see the gap by worst case and by RSS with the formulas written out.
- Asymmetric tolerances centred correctly
- PASS / FAIL against your minimum and maximum gap
- PDF report and Excel with live formulas
Everything in Measure & calculate.
