Fits & Clearances Calculator

indicative

Design standard

Calculation standard

Sets screening knobs for Indicative practice — not product type or catalog geometry

Tolerance, fits, cost, and toolpath screening.

Target SF 1.50

Reference standards

ISO 286ASME Y14.5

Validate — verify what you entered

Auto-design runs a solver-backed sizing search, applies the best candidate, then runs the full validation check.

PDF only (≤10 MB, first 5 pages). Vision extract is assistive — review before applying.

Fits & clearances

Enter nominal size and tolerances manually or use ISO 286 grade lookup.

Nominal size

ISO 286 auto lookup from nominal + grade

Typical Auto-design directions for fits & clearances.

Option	Basis	Pass	Tradeoff
Loose tolerance	Low cost	Check function	Higher variation
Functional tolerance	Assembly target	Pass expected	Balanced
Precision tolerance	High yield	High confidence	Higher cost
