Try it: Ski-pole basket

A powder basket stops your ski pole from sinking into the snow. You draw only half of one window. Mirror makes the full window, and Circular Pattern places all eight.

  1. Click Sketch and press Enter (XY-Plane). Draw two circles at the origin: Ø 90 and Ø 12.
  2. Draw a Constr. Line from the origin straight up to about (0, 45). This is the mirror line.
  3. With Line, draw (0, 16) → (6, 30) → (0, 40) and press Esc. Start and end on the construction line.
  4. Click Mirror and click the two lines. Press Enter, click the construction line and confirm Mirror 2 object(s)…. You now have a kite-shaped window.
  5. Click Circular Pattern. In Select Figures mode, click the four window lines. Choose Select Center and click the origin. Set Instances 8, Type Spread Evenly (360°) and click OK.
  6. Click Finish Sketch and Extrude 4 mm. For the hub, sketch circles Ø 22 and Ø 12 on the XY-Plane and Extrude them 18 mm.
