Title: Represent three-dimensional objects on a two-dimensional surface.
Course: Technology Education – Preparation (13099-II) > Section: Producing a Technological Solution

Representing three-dimensional objects on a two-dimensional surface may include

- using sketching paper or conventional drafting tools (e.g., drafting board, T-square, triangles)
- using computer-assisted drafting software and a computer.

Students may explore how producers and consumers rely on drawings to conceptualize, convey, update, and store designs and how the standardization of this process is required by all countries through international treaties and standards agreements.

Process/Skill Questions:

- What is the difference between an orthographic drawing and a pictorial drawing?
- What is the advantage of viewing an object in 3D vs. 2D?
- What are the advantages of computer-assisted drafting over conventional drafting techniques?
- What advantages does parametric modeling give a designer?
- Why is it important to standardize the way technical drawings and plans are drawn?
- Are technical drawings the property of the drafter or of his or her employer? Explain.
