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.
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
Use a school-approved offline or supervised tool and fictional data. Keep work private, respect media permissions and check accessibility.
