But CAD software is now able to create 2D drawings as well. (Some 2D graphics represent in-depth views of specific aspects.) Usually, an assembly drawing is used to show how different drawings relate to one another.ĢD drawings have traditionally been created manually using drafting supplies, such as a drafting table, pencil, and drafting tools for creating precise circles and curves. In addition to the part geometry, a drawing will also include qualitative information like the part’s designated materials and surface treatments as well as quantitative information like dimensions and tolerances.Ī sequence of 2D drawings that each depict the component from a different perspective or angle are often submitted by an engineer or drafter. But a 2D technical drawing’s two-dimensional views are only one component. What is 2D drawing?Ī 2D drawing, often known as an engineering drawing, is a sort of technical drawing used in the engineering field to communicate details about a part, such as its geometry, dimensions, and allowable tolerance.Īn engineering drawing depicts a part in two dimensions as opposed to a digital CAD file, which depicts the part in three dimensions. These 2D drawings may appear antiquated in comparison to CAD, but they are nevertheless an essential tool for communicating part design information, particularly information that a CAD file cannot effectively convey.
The generation of comprehensive, annotated technical drawings, which is the skill of drafting, hasn’t entirely been supplanted by digital files, despite the fact that they have sped up and simplified manufacture.
Engineers can now create a part using CAD software, submit the digital file to a manufacturer, and have the manufacturer create the part using digital manufacturing methods like CNC machining, all from the file. The way engineers collaborate with manufacturers has changed thanks to digital 3D data.
