Creating Digital Models

Overview

In this hands-on lesson, students use selected modelling software to create a basic digital model of a chosen object (e.g., a desk accessory, keychain, or simple character prop). They apply modelling concepts such as geometry creation, editing, proportions, and preparing the model for later use.

Learning intentions

• Students will create a simple 3D digital model using core modelling tools and commands.
• Students will apply safe, responsible technology practices when using software and storing files.
• Students will test and improve their model by checking shape, scale, and surface details.
• Students will document modelling decisions using clear notes or a short modelling log.

Success criteria

• I can build a basic model by using appropriate creation and editing tools (e.g., primitive shapes, transform tools, and refinement methods).
• I can adjust proportions, position, and details to meet a brief and quality checklist.
• I can save, version, and export my model in the required format for the unit portfolio.
• I can explain key steps I used and justify one improvement made after testing.

Curriculum links

• Digital Systems and Data: using digital tools to create, manipulate and manage digital information effectively.
• Design and Technologies Processes: plan, create and improve solutions through iterative testing and modification.
• Digital Technologies concepts: creating models and representing information using appropriate digital methods.
• Technologies communication: presenting processes and outcomes clearly for an audience.

Lesson structure (60 minutes)

1. 0–5 mins | Starter check-in & goals Teacher briefly revises modelling concepts from earlier lessons (primitives, transforms, editing, symmetry, and iteration). Students confirm their chosen object and the quality checklist they will use today.

2. 5–12 mins | Tool demonstration (live modelling) Teacher demonstrates the software workflow: creating a base shape, switching viewpoints, using transform/edit tools, and saving versions. Emphasis: “build first, refine next”, and how to avoid common errors (incorrect scale, wrong origin, messy history).

3. 12–22 mins | Guided build: base geometry Students begin modelling by creating the main form using primitives. Teacher circulates to check proportions and correct tool use, asking students to verbalise the purpose of each change.

4. 22–38 mins | Independent build: details & refinement Students add features (cuts, extrusions, bevels/rounding, holes, surface details) appropriate to their object. They pause mid-task to do a quick “test view” check: rotate the model, zoom for issues, and fix at least one problem.

5. 38–50 mins | Iteration & quality pass Students complete one improvement cycle: choose one aspect to enhance (smoothness, alignment, readability of shape, or correct scale) and apply changes. Students update their version name and add a short note in their modelling log: what changed and why.

6. 50–56 mins | Save, export & readiness Students save their final version and export required formats for the unit (e.g., a standard mesh file and/or image render). Teacher confirms file naming and that exports open correctly.

7. 56–60 mins | Exit reflection Students answer a quick prompt on paper or in a digital note: “What modelling choice helped the most, and what will I improve next time?” Teacher collects for formative feedback.

Resources

• Computers with the selected modelling software installed and signed in
• Teacher-made reference model screen record or printed workflow steps
• USB drive or cloud workspace with unit folder structure
• Student modelling checklist (scale/proportions, recognisable shape, clean surfaces, correct export)
• Headphones (optional) for focus; quiet workspace expectations
• Template for modelling log (steps taken, version, improvement)
• Example reference images of simple objects for inspiration
• Printer paper or digital submission guide for naming conventions

Assessment

• Formative: Teacher observations during guided and independent building (tool accuracy, iterative improvement, safe file management).
• Product: Digital model meeting the checklist and correct export/versioning.
• Process: Short modelling log explaining at least one improvement and the reason behind it.

Differentiation

• Support: Provide a scaffold with recommended primitive selection, basic dimensions, and a “minimum viable model” target; offer step-by-step micro-demonstrations for students who fall behind.
• Support for SEN: Allow use of checklists, visual diagrams for tool functions, and reduced feature sets while maintaining model quality and export requirements.
• Extension: Challenge students to add two additional modelling features (e.g., symmetry workflow, simple texture/colouring, or a more complex cut-out) and justify their design decisions.
• EAL: Provide sentence starters for the modelling log (e.g., “I changed… because…”, “My model improved by…”), and allow oral explanation to be recorded by the teacher.
