  • 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
  • Molecular modeling in CAD
    the top down, nanoscale "machines " will build products from the bottom up. CAD molecular-modeling engineering software is an important tool in
  • Mechanical-design software for modeling
    SolidWorks 3D mechanical-engineering software lets users quickly build solid models with familiar drag-and-drop, pointand-click, and cut-and-paste functions. Appearance callouts in the feature tree provide intuitive access to the model's properties. The Vent feature lets users take a geometry
  • Sketching software captures AEC ideas fast
    Download the free trial of SketchUp Pro 5 software, and it might get you hooked. The software is not CAD. SketchUp Pro 5 software lets users import scanned sketches and model directly from them by tracing over the images with the pencil tool. SketchUp Pro 5 provides a clean, simple-to-use interface
  • Software Review: Dressing up 3D Designs
    You are probably already familiar with Photoshop as nifty image-editing software that lets users crop and rotate pictures, and even adjust images down to the last pixel. The new Photoshop CS3 Extended targets engineering and product development, letting users make measurements and work with 3D
  • Forget general-purpose software -- Get Focused
    needs just a few selections and dimensions before showing a section of a wall partition. Zila's product configurator generates production drawings and a bill-ofmaterial after submitting an order. Results of one analysis shows stresses on a proposed die. The top image shows velocities in an extruding
  • Don't touch CAD until you've firmed up the concept
    at the screen top shows beam deflection and the screen shows its odd cross section. The software includes a library of over 100 built-in functions (for finding beam deflections, moments of inertia, perimeters, and lengths, for example) to make bidirectional associations between geometry and calculations
  • Preparing for a Fluid Simulation
    CFD software is easier to use, faster, and more effective. Algor 's CFD software optimized flow through the ink-feed channel in the manifold of Hewlett-Packard inkjet cartridges. The fluid-flow model features a hybrid mesh created directly from a STEP CAD file. InCAD technology in the software also
