This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit introduces 3D Computer Aided Design to pupils. They will investigate modern architects to understand the techniques and materials they use in sustainable housing. They will develop knowledge of TinkerCAD to design and present a model sustainable house.
Lesson Summary
You will learn to use Tinkercad to draw exploded diagrams.
Key Notes
- Exploded diagrams show how the separate parts fit together to be assembled.
- Each individual piece of a design needs to be drawn separately in an exploded diagram.
- Tinkercad has a notes tool that allows designers to make annotations.
- Tinkercad orthographic view shows designs to scale from the front, back, top, bottom and side views.
- Tinkercad orthographic view shows designs in isometric with shape sides drawn at 30 degree angles from the horizontal.
Vocabulary To Learn
- exploded digram: a drawing showing how separate components fit together
- perspective view: viewing 3D objects in 2D, where objects look smaller as they get further away
- orthographic view: viewing 3D objects in 2D to scale, showing each side of a design without perspective
- isometric: drawing 3D objects to scale, with shape sides drawn at 30 degree angles from the horizontal
- annotate: add notes or labels to something to help explain it
Common Mistakes To Avoid
- Exploded diagrams have to be in perspective view.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Exploded diagrams show how the separate parts fit together to be assembled. Each individual piece of a design needs to be drawn separately in an exploded diagram.
2. What does this key word mean in this lesson? 'exploded digram'
a drawing showing how separate components fit together.
3. Correct this common mistake.
Mistake: Exploded diagrams have to be in perspective view. Correction: Orthographic view is a better viewpoint for seeing the exploded parts of the eco-house.
