Week 5 — Sketch & Revolve (2D → 3D)

Focus Concept: Using Sketch and Revolve to create smooth curved 3D forms
Mini-Project: Revolved Rocket / Pendant

Connections to STEAM Learning

  • Computing: Turning 2D sketches into 3D objects using tools like Revolve.
  • Design & Technology: Designing simple products such as bottles, rockets or pendants.
  • Maths: Rotational symmetry and profiles.
  • Art & Design: Creating smooth, flowing shapes from simple outlines.
  • Engineering: Considering wall thickness and stability for printed parts.

This week participants use the Sketch tool to draw a 2D profile, then use Revolve to spin it into a 3D shape such as a rocket body, bottle or pendant.

Objectives

  • Create a simple, closed profile sketch.
  • Use Revolve to turn that sketch into a solid 3D object.
  • Adjust proportions so the final model looks sensible and stable.

Success Criteria

  • I can draw a profile that Revolve can turn into a solid shape.
  • I can choose a good axis and angle for the revolve.
  • I can tweak my design so it looks intentional and usable.

Key Vocabulary

  • Sketch — a 2D drawing used as the basis for a 3D model.
  • Profile — the outline that will be revolved.
  • Revolve — spin a profile around an axis to make a 3D object.
  • Axis — the line the sketch spins around.

Part A — Explore Sketch

  • Demonstrate how to open the Sketch tool and draw a simple side‑on outline.
  • Show how to make sure the profile is closed (no gaps).
  • Let participants practise drawing a basic cup or rocket profile.

Part B — Make: Revolved Rocket / Pendant

  • Learners choose whether to design a small rocket body, bottle, cup or pendant.
  • They draw a profile, then use Revolve to create the 3D form.
  • Adjust scale and proportions to make the design look practical.

Part C — Extend & Share

  • Add small extra details (fins, loop for pendant, simple base) using normal Tinkercad shapes.
  • Invite learners to show their profile and final 3D shape side by side.

Equipment

  • Laptops / Chromebooks with internet
  • Mouse per device

Safety & Setup Notes

  • For prints, avoid very thin edges or sharp points that could snap or be uncomfortable to touch.
  • Remind learners to keep model sizes sensible to avoid long print times.
