TS 3434

TS 3434 defines the general principles for determining section and view areas in building and civil engineering drawings. In technical drawing practice, sections and views are the basic means used to make the shape, position, and surface relationships of a building element legible; this standard provides a common framework for organizing those representations.

In general technical terms, a section shows an object as if it were cut by a chosen plane, while a view presents its external form by projection from a selected direction. That distinction matters because architectural and engineering drawings must communicate dimensions, openings, surfaces, and element boundaries without ambiguity. The scope of TS 3434 does not include identifying materials or components; it is concerned with how areas are represented as sections and views, not with specifying what the object is made of.

Why section and view conventions matter in drawings

Rules of this kind help different project disciplines interpret the same drawing consistently. In building and infrastructure work, clear separation of walls, slabs, openings, structural members, and other geometric elements depends on a disciplined relationship between plan, section, and elevation-type views. TS 3434 is recorded as equivalent to ISO 4069:1977, placing it within a shared international approach to drawing representation.
