CADdesign

CADdesign refers to the practice of using computer-aided design software to create, edit, analyze, and document digital representations of objects and systems. It covers 2D drawings and 3D models used in engineering, architecture, manufacturing, and related fields. CAD design streamlines drafting, enables precise geometry, and supports simulation and manufacturing workflows.

Modern CAD systems provide parametric and direct modeling, constraints, assemblies, and bills of materials. They support features such as rendering, finite element analysis, kinematic simulation, and clash detection. Data management includes version control, revision history, and collaborative workflows across design teams.

Typical CAD workflows include concept sketching, digital modeling, refinement, validation, and drawing production for fabrication or construction. CAD files can feed directly into computer-aided manufacturing (CAM) and product lifecycle management (PLM) systems, enabling a cohesive design-to-production pipeline. CAD also supports documentation, quality control, and change tracking.

Formats and interoperability are important considerations. Core file formats include DWG, DXF, STEP, and IGES. Interoperability between systems is often addressed through neutral formats and standards, with building information modeling (BIM) playing a key role in architecture and construction.

History and scope: CAD originated in the mid-20th century with early computer graphics and became widely adopted in the 1980s and 1990s, enabling parametric design and complex assemblies. Today, CAD integrates with simulation, optimization, and manufacturing ecosystems to shorten development cycles.

Notable software packages include AutoCAD, SolidWorks, CATIA, Siemens NX, PTC Creo, and Revit, each serving different industries and workflows.
