Forget pumpkin carving, get pumpkin CADing with this simple Halloween CAD tutorial? No knife required!
- Begin by importing a sketch. Use Attach Raster Image (IMAGEATTACH).
- Next, trace the outline either using POLYLINE or SPLINE. You only need to trace half the pumpkin.
- HIDE or ERASE the image. You no longer need this.
- OFFSET the edge.
- EXTEND the edges to the centerline.
- Draw a LINE connecting the ends.
- Use JOIN to create to closed shapes (red and blue).
- Use the Manipulator to lift the inner shape up slightly.
Note: You can learn more about manipulating entities on Heidi’s blog.
- LOFT between the shapes.
Note: you might need to convert the spline to a polyline. Read more about polylines and splines.
- Use ARRAYPOLAR to repeat the shape.
That’s looking pretty good, but now I want to tweak the shape so everything overlaps properly.
- Hover over the array and hold Ctrl adjust the array.
Alternatively, use the Properties Panel to adjust the array.
- EXPLODE the array.
- Use UNION to join the solids. This completes the “body” of the pumpkin.
- Draw a POLYGON.
- COPY the shape
- Use ALIGN to move the copied shape into position.
- LOFT between the two shapes. This time use the option “Guides”. The loft will now distort along the curve.
Hint: the simpler the guide curve the better the result.
- Create a CYLINDER inside the body.
- FILLET the edges.
- SUBTRACT the solid from the body.
- EXTRUDE the face using the “Subtract” mode.
