Part 1131:
Application module: Construction geometry

1 Scope

This part of ISO 10303 specifies the application module Construction geometry. The following are within the scope of this part of ISO 10303:

• geometric primitives of one and two dimensions;

  EXAMPLE 1   Points, lines, and planes are used to construct more complex geometry that represents the shape of products and features of products.

  EXAMPLE 2   Points, lines, and planes can represent the derived centres of ideal symmetric features of size found in product definitions.

  EXAMPLE 3   Points, curves, and surfaces can represent the derived centres of imperfect features of size measured on real workpieces.

• geometry used in the construction of two-dimensional and three-dimensional shape representations;
• association of a construction geometry to a geometric model or a construction from which it is derived;
• items within the scope of application module Basic curve, ISO/TS 10303-1651.

The following are outside the scope of this part of ISO 10303:

• constructive solid geometry primitives and methods;
• geometry of dimension greater than three;
• geometry for the representation of properties other than shape.
