Configuration
Spec deviation +iUpper deviation from nominal stackAdded to the nominal sum to form the absolute USL. A drawing tolerance, not a measured process limit.
Ref+/-0.100 mm typical (ISO 286)
Spec deviation -iLower deviation from nominal stackSubtracted from the nominal sum to form the absolute LSL.

Predicted Analysis Ready
Configure the stack and choose a distribution per dimension. Values update live from the deterministic Decimal engine. Predicted, drawing-based — verify with measured process data before any release.
