ISO 8560:2019 pdf free.Technical drawings——Construction drawings——Representation of modular sizes, lines and grids.
1 Scope
This document lays down rules for the representation of modular sizes, lines and grids on construction drawings. The basic module M is 100 mm (see ISO 1006).
Generally, modular sizes are for use on design drawings, but can also be added to production drawings for manufacturing, orientation and location.

4 General
Drawings with modular sizes shall be executed in accordance with ISO 128-1 and ISO 129-1. If necessary,the drawings should have a note indicating that modular sizes are being used.
5 Designations of modular sizes
Drawings with sizes indicated in modules (instead of in millimetres or metres) should have a clear note explaining that this is the case.
The designations of modular sizes shall be as follows: Modular: nx M Basic module: M Multimodules:
3 M,6 M,12 M Modular sizes: 10M Multimodular sizes: 10x3M,5x 6 M Non-modular, if needed: M
6 Representation of modular lines and sizes
6.1 General Modular lines and sizes shall be represented in accordance with the following figures.
6.2 Modular and multimodular lines Modular and multimodular lines shall be drawn using a continuous line (see Figure 1). The lowest level shall be drawn using a continuous thin line.
6.3 Modular line in an axial position Where necessary for reasons of clarity, a modular line in an axial position may be indicated by a chain line (see Figure 2).
6.4 Circle for identification of modular line Where necessary for identification purposes, multimodular grid lines shall be terminated with a circle
drawn with a thin line (see Figure 3).
6.5 Designation of modular line The line may be designated by a reference inside the circle (see Figure 4).
6.6 Terminations for the size of a modular zone Terminations for the size of a modular zone shall be the same as for single sizes, as specified in ISO 129-1 (see Figure 5).
7 Representation of modular grids
7.1 General Modular grids shall be drawn with modular lines and shall be represented in accordance with the following figures.
7.2 Modular grid with different line intervals Modular grids with different line intervals which are superimposed may be clarified by using a thin line for the smallest interval, a thick line for the next largest interval, and so on. (see Figure 6).
7.3 Indication of modular sizes Indication of the size of a grid line interval is shown in Figure 7.
7.4 Indication of modular zones Indication of a modular or a non-modular zone is shown in Figure 8.
7.5 Indication of a change in direction of a modular grid Indication of a change in direction of a modular grid is shown in Figure 9.ISO 8560 pdf download.
