Pack: F_OVERLAY Severity: major

General tolerance note must be present when ISO 2768-fH is used

Rule Card

Field Value
Pack F_OVERLAY — Industry Overlay and Compliance
Title General tolerance note must be present when ISO 2768-fH is used
Severity major
Check logic Deterministic
Applies to Compliance overlay
Inputs required drawing_title_block
Fix template Add to title block: 'General tolerances ISO 2768-fH' (and, if referencing ISO 2768-2, add ':1989' or adopt ISO 22081 explicitly).

Short Description

Ensures the drawing explicitly states ISO 2768-fH as the default general tolerance class for unspecified dimensions, to avoid uncontrolled tolerance assumptions.

When It Applies

This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
