GD&T is a language of symbols for technical drawings. Two main standards exist: ISO GPS and ASME Y14.5. ASME Y14.5 is the most widely used standard
Standard provides symbols for welded components on technical drawings. Applies to both brazed and soldered joints. Allows direct indication of weld specifications at the weld
Vector graphics create images from geometric shapes defined on Cartesian plane. Basic primitives include points, lines, polygons, and parametric curves. Shapes can be combined with properties like color and size
Axonometry generates planar images of three-dimensional objects using coordinate axes. Resulting parallel projections are generally oblique, but can be orthographic. Axonometric perspective preserves volume impression in technical drawing
Defines rules for symbolic representation of welded joints on technical drawings. Applies to both brazed and soldered joints. Allows two different approaches to arrow side and other side designation
Defines rules for symbolic representation of welded joints on technical drawings. Applies to both brazed and soldered joints. Recognizes two different systems: A (dual reference line) and B (single reference line)
