  1. Chapter 9Sweep, Curves and Loft

  2. Sweep/Cut Sweep • Extrude/Cut a feature along a sketched path

  3. Sketch Paths • Helical/Spiral Curves • First create a circle sketch • Then go to curves >> helix and spiral • Composite Curves • Combine multiple sketches • Projected Curves • Sketch on Sketch • Sketch on Face • Curves through XYZ/Reference points • Specify points in space

  4. Cosmetic Thread • Saves memory • It’s a symbolic threading. Doesn’t actually cut the part, but it provides enough information to be used in the technical drawing

  5. Lofting • Create profiles of the extrusion on different planes, and the loft inerpolates the feature’s shape • Make sure to use guide curves here

  6. 3D Sketches • Similar to composite curves, but you make all the sketches on their planes at once

  7. Do Examples 9.1, 9.2
