Defines the resource constructs for representation of dimensions and tolerances of product shapes. The dimensions define the sizes of a shape and locations of identifiable portions of a shape.

This part of ISO10303 specifies the resource constructs for representing dimensions and tolerances of product shapes. The dimensions specify the sizes of a shape and locations of identifiable portions of a shape. The tolerances specify the allowable deviation of a product from its defined shape and dimensions. The representations of dimensions and tolerances provided by this part of ISO10303 are appropriate for use with both 2D and 3D geometric models of parts.

The following are within the scope of this part of ISO10303:

  • tolerances as constraints on the shape characteristics of a product;

  • the specification of the tolerances on a defined shape;

  • the representation of geometrical tolerances and plus-minus tolerances;

  • the representation of tolerance values;

  • the representation of dimensions;

  • the assignment of size characteristics to a shape;

  • the assignment of location and orientation characteristics to a shape;

  • the specification of datums and datum references;

  • the identification of derived shape elements such as centre lines and intersections;

  • the structure for limit and fit systems for shapes.

The following are outside the scope of this part of ISO10303:

  • the definition of the fundamental principles, concepts and terminology of tolerancing and dimensioning;

  • the mathematical definition of tolerances and datums;

  • the description of dimensioning or tolerancing practices;

  • the specification of dimensional inspection methods;

  • the synthesis and analysis of tolerances;

  • the tolerancing of product characteristics other than shape;

  • the presentation of tolerances on engineering drawings;

  • the specification of surface finish or surface roughness.
