Poollõiget

Poollõiget is an Estonian term that translates to "half-cut" or "half-section" in English. It is a technical term used in engineering and technical drawing to describe a specific type of view. A poollõiget is created by imagining an object is cut in half, and then displaying only one half of the object, with the cutting plane shown as a solid line. This view is particularly useful for illustrating the internal structure of symmetrical objects where a full section view would be redundant.

The purpose of a poollõiget is to reveal internal features without obscuring the external shape of the object. By showing only half, the clarity of both internal and external details is maintained. This is especially beneficial for components that have complex internal geometries. The cutting plane line in a poollõiget is typically a thin solid line with alternating long and short dashes, indicating where the imaginary cut has been made. Arrows are often used to show the direction in which the remaining half is viewed.

This type of drawing convention helps to reduce the amount of drawing space required while still providing comprehensive information about the object's design. It is a common practice in mechanical engineering, architecture, and other fields that rely on detailed technical illustrations to communicate design intent and manufacturing specifications. The use of a poollõiget is governed by established standards to ensure consistency and understanding among professionals.
