tasopiirros

Tasopiirros is a two-dimensional technical drawing produced on a flat plane that represents an object through orthographic (non-perspective) projection. It presents the shape and features at a chosen scale, using standard line types and dimensioning to communicate measurements, tolerances, and construction details.

A tasopiirros typically includes multiple views, such as a plan (top view), front elevation, and side elevation. Additional sections or detail views may be added to show internal features. The drawing uses conventions for visible, hidden, and center lines, and it specifies dimensions and notes to enable manufacture or construction.

Views are arranged according to regional standards, commonly following either first-angle or third-angle projection depending on the country or industry.

Tasopiirros differs from perspective or pictorial drawings, which aim to depict depth and appearance from a viewpoint. It is a foundational method in technical drafting and is widely used in architecture, engineering, and manufacturing, both on paper and in computer-aided design.
