Joonetüübid

Joonetüübid refers to the different kinds of lines used in technical drawings and other visual representations. These lines serve specific purposes and are standardized to ensure clarity and avoid ambiguity. The most common types include visible outlines, hidden outlines, center lines, dimension lines, and cutting planes.

Visible outlines are typically solid, dark lines used to represent the visible edges and surfaces of an object. Hidden outlines, often depicted as dashed or dotted lines, indicate edges and surfaces that are not visible from the current viewpoint. Center lines, consisting of alternating long and short dashes, are used to denote the center of circles, arcs, and symmetrical features. Dimension lines, also solid and dark, are used to indicate measurements, with arrows or ticks at their ends showing the extent of the dimension. Cutting planes are usually shown as thick, dashed lines with arrows, indicating the path of an imaginary cut through an object to reveal its internal structure.

The precise appearance and weight of each joonetüüp can vary slightly depending on the specific industry standards or conventions being followed, such as ISO or ANSI. However, the fundamental principles of using distinct line types to convey different types of information remain consistent. Understanding and correctly applying these joonetüübid is crucial for anyone involved in creating or interpreting technical documentation.
