Tolerance Stackup

WC · RSS · Monte Carlo

Build an assembly chain and instantly analyse worst-case, statistical (RSS) and Monte Carlo tolerance scenarios. A live proportional chain diagram updates as you add parts — showing each dimension's direction and signed contribution.

  • Worst Case — guaranteed 100% yield, full tolerance loop
  • RSS (Root Sum of Squares) — statistical assembly model
  • Monte Carlo — 100 000-sample simulation with yield %
  • Live chain diagram: proportional blocks, direction rows
  • +1 / −1 direction with gap equation updated in real time
  • Sensitivity analysis — which part contributes most?
  • Dark & light theme, export-ready results

GD&T Reference

All 14 Symbols · Interactive

A complete Geometric Dimensioning & Tolerancing reference and learning tool covering every symbol in the ASME Y14.5 standard — with interactive SVG diagrams, tolerance zone illustrations, and application notes.

  • Form — flatness, straightness, circularity, cylindricity
  • Orientation — perpendicularity, angularity, parallelism
  • Location — position, concentricity, symmetry
  • Runout — circular & total runout
  • Interactive diagrams with adjustable tolerance values
  • Feature Control Frame builder & symbol guide
  • Light & dark mode, printable reference cards
