3D modeling with CAD

Image of 3D modeling process with CAD software

Computer-aided design (CAD) uses computer systems to create designs of industrial parts. CAD models nowadays often involve more than just one part. Assemblies consisting of more than a thousand parts can be created, modified, analyzed and optimized with commercial available CAD tools. Generations of a single part starts with a two-dimensional sketch. The user must enter planar dimensions of an object and extrude, revolve or sweep the sketch along a path to create a three-dimensional structure. Additional operations, such as cutting or splitting are used to modify the structure until a designer obtains the final design. The image shows a project, where I used a free 3-D sample data (weldment structure) to analyze the fatigue behavior under different load conditions
