TS EN ISO 8560

TS EN ISO 8560 is a technical drawing standard for showing modular sizes, lines and grids on construction drawings. In practical terms, it helps drawings communicate the same dimensional logic across design and building documentation, so the layout of a structure can be read consistently by different disciplines. The basic module is M 100 mm, and the modular system is linked to ISO 1006.

Why modular coordination matters in building drawings

In general technical practice, modular coordination is a way of planning building dimensions around a common unit. It supports alignment between structural bays, openings, panels and other repeating elements, reducing ambiguity when drawings are interpreted by designers, engineers and manufacturers. According to the scope of this standard, modular sizes are mainly intended for design drawings, but they may also be added to production drawings to assist manufacturing, orientation and location. That makes the drawing not only a geometric record, but also a coordination tool.

Lines, grids and the reading of spatial order

Lines and grids are central to construction drawing because they show axes, alignment and repeated spacing. In building projects, these graphical references help coordinate components across plans, sections and details, especially where regular spacing or a structural grid controls the layout. The value of this standard lies in giving a common representation method for modular organisation, so that the drawing can express both size and positional structure clearly.

• Representation of modular sizes on construction drawings
• Use of the 100 mm basic module M
• Optional addition of modular sizes on production drawings
• Graphical communication of lines and grids for layout coordination
