A 3D solid representing a building's structural member is modelled as a prism with a base area of 2.4 m2 and a height of 3.0 m. When the same member is shown in a 2D drawing such as a plan view, what geometric change occurs in its representation?
- 1One spatial dimension (height) is removed, and only the area is represented✓
- 2The overall volume of the solid becomes reduced to half its original value
- 3The apparent thickness of the member becomes twice its actual size on paper
- 4The original prism is transformed into a circular or spherical figure in 2D view
Correct answer
One spatial dimension (height) is removed, and only the area is represented
