TS 88-30 ISO 128-30

TS 88-30 ISO 128-30 addresses the basic conventions for presenting views in technical drawings, based on orthographic projection methods. It provides a common framework for how views are arranged and shown across different drawing disciplines such as mechanical, electrical, architectural, and civil engineering documentation.

In technical drawing, a view is a two-dimensional representation of a three-dimensional object from a particular direction. Front, top, and side views are used together to make geometry easier to read and compare. The subject of this standard is the general way such views are presented; the broader engineering value lies in keeping drawing communication clear, consistent, and widely understandable.

Why view conventions matter

When orthographic views are laid out consistently, designers, draughtspersons, manufacturers, and inspectors can interpret the same object with less ambiguity. Views complement dimensions and notes by showing shape and relationship, especially for parts with complex profiles or hidden features. In general technical practice, this convention is one of the foundations of standardized engineering communication.

What the listing covers

• It covers general principles for presenting views in all kinds of technical drawings.
• Its scope is tied to orthographic projection methods specified in ISO 5456-2.
• The document is about view presentation, not a blanket rule set for every drawing convention in engineering graphics.
• This TSE listing is shown as withdrawn, so it should be treated as a historical reference rather than an active standard.
