One view can hide an important feature

1 · Learn

A three-dimensional model has width, height and depth. A front view may hide depth; a top or side view can reveal a feature that seems absent from the front. Use consistent units when entering dimensions.

A 3D model on screen is a representation, not automatically a safe or printable physical object. Check the design's purpose and constraints before judging success by appearance alone.

Key words and supplied examples.

2 · Worked example

A box looks square from the front but is only 2 units deep. I rotate the view to inspect depth instead of assuming it is a cube.

3 · Your turn

Does a square front view prove a model is a cube?

Check your answer

No. Its depth and other dimensions may differ; inspect more views and measurements.

4 · Apply your learning

Create a simple box in an approved modelling tool and compare its front, side and top views.

Adult guidance and safety
