Tehnikajoonised, commonly referred to as technical drawings, are a specialized form of visual communication used in engineering, architecture, and manufacturing. They are precise graphical representations that convey detailed information about an object's design, dimensions, materials, and construction methods. Unlike artistic sketches, technical drawings follow strict conventions and standards to ensure clarity and unambiguous interpretation across different disciplines and geographical locations.

The primary purpose of a technical drawing is to provide a complete and accurate blueprint for creating or constructing a physical item. This includes specifying the exact size and shape of components, their relationships to each other, and the tolerances required for proper fit and function. Information such as surface finish, material properties, and assembly instructions can also be included.

Various types of technical drawings exist, each serving a specific purpose. Orthographic projections, such as front, top, and side views, are fundamental for depicting an object's geometry from multiple perspectives. Isometric and dimetric projections are examples of pictorial drawings that offer a three-dimensional representation. Detail drawings focus on specific, intricate parts, while assembly drawings illustrate how components are put together.

The creation of technical drawings relies on precise linework, symbols, and annotations. Standardized line types, such as solid lines for visible edges and dashed lines for hidden edges, help to organize the information. Dimensions are applied using specific notations to indicate measurements and tolerances. The use of Computer-Aided Design (CAD) software has become ubiquitous in modern technical drawing, allowing for efficient creation, modification, and sharing of these critical documents.
