Helix Challenges
Create the screw by modelling the main shank and forming the thread using a helice. Use the pitch and profile dimensions from Section A‑A to define the helix.
Learning Intentions
Create a helice for threads using a profile + helix path.
Blend geometry using a partial revolve (180°).
Combine sweep, revolve, fillets, and projection techniques in one part.
Success Criteria
Thread profile matches Detail E and Section A‑A.
Helix follows correct pitch and depth.
Head blends cleanly using the 180° revolve.
Fillets and dimensions match the drawing.
