Forget pumpkin carving, get pumpkin CADing with this simple Halloween CAD tutorial? No knife required!

The Body

  1. Begin by importing a sketch. Use Attach Raster Image (IMAGEATTACH).
  2. Next, trace the outline either using POLYLINE or SPLINE. You only need to trace half the pumpkin.
  3. HIDE or ERASE the image. You no longer need this.
  4. OFFSET the edge.
  5. EXTEND the edges to the centerline.
  6. Draw a LINE connecting the ends.
  7. Use JOIN to create to closed shapes (red and blue).
  8. Use the Manipulator to lift the inner shape up slightly.
    Note: You can learn more about manipulating entities on Heidi’s blog.
  9. Rotate.
  10. Mirror.
  11. LOFT between the shapes.
    Note: you might need to convert the spline to a polyline. Read more about polylines and splines.loft pumpkin halloween CAD tutorial
  12. Use ARRAYPOLAR to repeat the shape.
    That’s looking pretty good, but now I want to tweak the shape so everything overlaps properly.array polar pumpkin halloween CAD tutorial

    Alternatively, use the Properties Panel to adjust the array.array polar pumpkin halloween CAD tutorial

  4. LOFT between the two shapes. This time use the option “Guides”. The loft will now distort along the curve.
