Description (English):

ISO 1101:2017 defines the symbol language for geometrical specification of workpieces and the rules for its interpretation. It provides the foundation for geometrical specification. The illustrations in this document are intended to illustrate how a specification can be fully indicated with visible annotation (including e.g. TEDs). NOTE 1 Other International Standards referenced in Clause 2 and in Tables 3 and 4 provide more detailed information on geometrical tolerancing. NOTE 2 This document gives rules for explicit and direct indications of geometrical specifications. Alternatively, the same specifications can be indicated indirectly in accordance with ISO 16792 by attaching them to a 3D CAD model. In this case, it is possible that some elements of the specification are available through a query function or other interrogation of information on the model instead of being indicated using visible annotation

Abstract

Overview

EN ISO 1101:2017 (ISO 1101:2017) is the international standard that defines the symbol language and interpretation rules for geometrical product specifications (GPS). It establishes the foundation for indicating and reading geometrical tolerances on engineering drawings and CAD models, covering tolerances of form, orientation, location and run‑out. The standard supports explicit visible annotation (including Theoretically Exact Dimensions - TEDs) and notes that equivalent indications may be attached indirectly to 3D CAD models (see ISO 16792).

Key topics and requirements

Symbol language and rules: Standardized symbols and syntax for expressing geometrical tolerancing unambiguously.
Toleranced features and tolerance zones: Definitions and defaults for tolerance zones, including variable‑width, cylindrical and spherical zones.
Datums and datum systems: Rules for datum indications and how datum references control orientation and location.
Geometrical specifications: Formal definitions for straightness, flatness, roundness, cylindricity, line/surface profile, parallelism, and other characteristics.
Annotation conventions: How to present tolerance indicators, feature identifiers, stacked tolerances, supplementary indications and drawing defaults.
Advanced constructs: Intersection planes, orientation planes, direction features, collection planes, projected toleranced features and restrictive specifications.
CAD integration: Guidance that specifications may be indicated indirectly via 3D CAD (ISO 16792) with possible query/metadata access instead of visible annotation.

(These topics reflect the standard’s content structure and mandatory interpretation rules; specific measurement procedures and supplemental details are provided by referenced standards.)

Practical applications

Create unambiguous, standardized mechanical drawings and technical documentation for manufacturing.
Communicate tolerancing requirements between design, manufacturing and quality teams.
Define inspection criteria for metrology, coordinate measuring machines (CMM) and surface analysis.
Annotate 3D CAD models with GPS data for model‑based definition (MBD) workflows.
Support contractual specifications between OEMs and suppliers to ensure consistent part acceptance.

Who should use this standard

Mechanical, manufacturing and design engineers
CAD modelers and MBD practitioners
Quality engineers, metrologists and inspection labs
Technical drafters and standards managers
Contract engineers and sourcing/specification teams
