This representation mode may be used particulary when it is not necessary to show the exact form and size and where the designation of standardized centre holes is sufficient for information. Annex A gives the dimensions for types R, A and B, and Annex B the proportions and dimensions of symbols.
Abstract
Overview
ISO 6411:1982 - Technical drawings - Simplified representation of centre holes defines a compact way to show centre holes on engineering drawings when the exact form and size are not required. The standard lets designers use (e.g., “‑B 2,5/8”) instead of full detailed geometry. Annex A provides preferred dimensions for types , and Annex B gives symbol proportions and drawing‑presentation rules.
