Spatial Reasoning using Cubes and Isometric Drawings Part Three: Other 2D Representations -- Building Plans
Part Two explored isometric drawings as one way to represent a 3D shape. In this activity you will compare isometric drawing with another
type of representation called, a front-right-top view.
Activity 2: Building from the Front-Right-Top Views
Below are some sets of FRT views. Click on the button below to use the drawing tool to try to construct isometric drawings that match
each set of FRT views. Then copy each drawing onto isometric dot paper.
Hint: It might help to keep the FRT Tool open while you draw!
Reflections:
1. Do you think the front-right-top representation contains all the same information as an isometric view?
2. In the previous activities you saw that sometimes two solids have the same FRT view but different isometric views.
Do you think it is possible for two solids to have the same isometric drawing, but different FRT views? If so, create an example
using the drawing tool. If not, convince a partner why.
3. For what applications might a FRT view be more useful than an isometric view?
For what applications might an isometric view be more useful?
