From Sketch To CAD

Overview

In this seventh lesson of Crafting Cultural Connections: Lasercut Jewellery, students move from hand-drawn ideas to a digital CAD model. They learn essential software tools through a short shapes exercise, then import and refine their jewellery designs so they are ready for later laser cutting.

Learning intentions

Students will:

• learn how to navigate the CAD workspace and use basic design tools
• create and edit simple geometric shapes digitally
• translate a jewellery sketch into a clear CAD design
• apply appropriate dimensions, spacing, and design decisions for laser cutting
• work collaboratively and safely while using digital technology

Success criteria

• I can successfully create a basic design in CAD using shapes and editing tools.
• I can import my jewellery design into the CAD programme.
• I can check that my design is closed, appropriately sized, and suitable for lasercutting.
• I can explain one design decision connected to my cultural inspiration.

Curriculum links

• Technology — Technological practice: planning, developing, and evaluating a design outcome for a specific purpose and user.
• Technology — Designing and developing digital outcomes: using digital tools to create, manipulate, and communicate a design.
• Technology — Knowledge of technological products and systems: recognising how material properties and manufacturing processes influence design decisions.
• Key Competencies — thinking; managing self; participating and contributing; relating to others.

Lesson structure (60 minutes)

1. 0–5 min · Reconnect and hook. Open with the CAD introduction deck and show a comparison between a hand-drawn jewellery sketch and a precise digital file. Ask: “What must change before this design can be cut accurately?” Students discuss with a partner and identify one feature that needs precision.

2. 5–12 min · Demonstrate the workflow. Use the CAD introduction deck to introduce the CAD workspace, selecting, zooming, undoing, drawing shapes, resizing, grouping, duplicating, importing, and saving. Demonstrate the difference between a sketch and a closed digital outline, and model how to check scale, line placement, spacing, and unwanted overlaps. Remind students to use culturally respectful design choices and not copy protected patterns or symbols without permission.

3. 12–22 min · Guided shapes challenge. Students work in pairs at computers while the teacher follows the CAD introduction deck step by step. Each student creates a simple design containing a circle, rectangle, triangle, and repeated pattern, then practises resizing, aligning, rotating, grouping, and undoing. Partners take turns as “navigator” and “designer”, changing roles after each feature.

4. 22–27 min · Import and file-management demonstration. Demonstrate importing a previously photographed or scanned jewellery sketch, positioning it on the CAD workspace, and tracing or adapting it with simple digital shapes. Model naming the file clearly and saving it in the correct class folder. Students watch for the three checks: correct scale, closed outlines, and no accidental duplicate lines.

5. 27–48 min · Independent design development. Students use their own sketches and import or recreate their jewellery designs in CAD. They work in pairs for support but each student produces and saves an individual file. Circulate with the CAD design checklist and conference with students about cultural meaning, clarity of form, dimensions, holes for attachment, and whether the design could be cut from the selected material.

6. 48–55 min · Peer quality check. Display the CAD introduction deck and ask students to pause their work. Partners inspect each other’s screen using the checklist: design imported or recreated, outline closed, suitable size, no overlapping or stray lines, attachment hole included if needed, and file saved correctly. Students make one improvement and record one question for the next lesson.

7. 55–60 min · Plenary and exit check. Return to the CAD introduction deck for the final prompts. Students show a basic CAD feature they can now use, name one change made from sketch to digital design, and submit the worksheet or tell the teacher whether their file is ready for further checking.

Resources

• Computers or laptops with the selected CAD software installed
• Projector or interactive display
• CAD introduction deck
• CAD design checklist
• Students’ approved jewellery sketches or scanned design files
• Shared class folder or learning-management system
• Sample CAD file showing a suitable and unsuitable laser-cut outline
• Appropriate computer-workstation and laser-cutter safety reminders

Assessment

• Observe students during the shapes challenge, checking navigation, use of basic tools, collaboration, and safe computer practice.
• Check each saved CAD file for imported or recreated design, closed outlines, suitable scale, clear spacing, and evidence of revision.
• Use the worksheet and plenary responses to identify students requiring a further guided tutorial before laser cutting.

Differentiation

• Pair students strategically so confident users can support peers; require partners to explain rather than take over the mouse and keyboard.
• Provide a guided tutorial or teacher-led small group for students needing support with importing, selecting, resizing, grouping, or saving.
• Offer a visual step sequence, enlarged screenshots, key vocabulary, and repeated modelling for students with literacy, processing, or language needs. Allow students to use their sketch as a reference throughout.
• Reduce the initial task to one simple pendant shape and one attachment hole where needed, then build complexity gradually. Check understanding privately and frequently.

Extension

• Students explore advanced CAD features such as duplicating and mirroring, combining shapes, creating repeated patterns, or using layers and precise measurements.
• Students develop a more complex but still cuttable design, explain how the added feature strengthens its cultural connection, and justify why it remains practical for the material and manufacturing process.
