lõikuspinnast

Lõikuspind is an Estonian term that translates to "section plane" or "cutting plane" in English. It refers to an imaginary plane used in technical drawing and engineering to reveal the internal structure of an object. When a solid object is conceptually cut by a lõikuspind, the view presented shows the shape of the object as if it were sliced. This allows designers and engineers to illustrate features, dimensions, and construction details that would otherwise be hidden from external view.

The lõikuspind is typically depicted by a cutting line in a principal view, indicating where the imaginary cut is made. Arrows are often used to show the direction in which the section view is observed. The parts of the object that are intersected by the lõikuspind are then shown with hatching lines, which vary in pattern and density depending on the material. Different materials can be distinguished by unique hatching patterns.

Section views created by a lõikuspind are crucial for understanding the internal geometry of parts, which is essential for manufacturing, assembly, and analysis. They can reveal hidden holes, internal passages, material thickness, and the arrangement of components within an assembly. Various types of section views exist, such as full sections, half sections, offset sections, and broken-out sections, each serving specific purposes in illustrating internal details. The clarity and accuracy of a lõikuspind in a technical drawing are paramount for effective communication of design intent.
