  • CAD software generates picture-perfect designs
    I started using the TurboCAD solid modeler in 2002, and still get excited about it. I first stumbled across the program at a local office-supply store while seeking software that would let me create striking 3D illustrations for a book. The CAD software is now my trusted business partner. I have
  • A search engine for CAD geometry
    is a representative part for a group of similar parts. Background circles indicate a relative number of similar parts. The software searches through candidates by comparing tessellated (made of tiny triangles) versions of CAD geometry. (All CAD programs produce tessellated representations.) The geometry
  • Comparing 3D CAD modelers
    , moving 600 components and changing the length of 28 others (right-hand image). CAD software with what is called a history-based approach to design has topped the field in market share since Needham, Mass., introduced Pro/ Engineer in the late 1980s. About a year ago, Ft. Collins, Colo., started
  • The future of CAD: driving revolution in 3D
    mechanical-design packages leave plenty of room for improvement. As with every area of computing, 3D mechanical-design software still needs to be faster, easier to use, and more useful for communicating with nonengineers. In the years to come, 3D CAD software will steadily improve engineering productivity
  • No CAD geometry? No problem for parametric FEA
    A parametric FEA program now lets engineers manipulate shapes and positions of features in meshed models without accessing the original CAD model or CAD software ), lets analysts extensively change FEA geometry for designs studies. For instance, cross members on a truck frame might be thickened
  • CAD package pumps up the parametrics
    NX CAD software goes one step beyond its already capable parametric features by including what's called "direct modeling." The surfboard initially had several mounting holes located at the rear. The Simplify command removed holes under the specified diameter of 2 in. The Move Region command rotated
  • Curvy robo-caddy takes shape with CAD
    Designer Mark Stewart at Stewart Golf in England, turned to surface and solid-modeling CAD software to make their electric golf caddy stand out on the course. The X1R (with remote control) weighs about 14 kg. There is also a model steered manually which weighs ), turned to surface
  • Online CAD collaboration includes PDM and more
    A mechanical design program called Alibre Design complements high-end CAD systems with collaboration features and low-cost design seats. It also serves as an entry to solid modeling for engineers looking to shift from 2D to 3D design. The software's easy-to-use design tools and collaboration
