CAD (Computer-Aided Design)
Computer-Aided Design (CAD) is the use of software to create 2D drawings and 3D models of physical objects. CAD tools range from 2D drafting software (AutoCAD) to parametric solid modelers (SolidWorks, Creo) to surface modeling tools (CATIA, Alias) to simulation-integrated environments (NX, Fusion 360). CAD is the starting point of the digital product record that PLM manages.
In context
An aerospace tier-1 supplier creates a bracket in CATIA V5, releases the geometry into Windchill PLM, and the CAD file becomes the authoritative geometric definition driving the downstream CNC machining program, FEA analysis, and technical data package submitted to the OEM. The CAD tool selection — SolidWorks, CATIA, NX, or Creo — largely determines which PLM platform can integrate natively and which file translation standards are required for supply chain data exchange.
Why it matters
CAD is where engineering knowledge is first formalized as data. The CAD file is the authoritative geometric definition of a product component — the input to PLM, simulation, manufacturing, and service systems. CAD tool selection constrains PLM selection, simulation tool selection, and supply chain data exchange standards.
