Lesson 2: Drawing Scale Diagrams

This is a photo of two people looking over house blueprints.

Creatas/Thinkstock

Architects, drafters, salespeople, home buyers, and contractors all make use of blueprints from a home's conception to its completion. Blueprints outline all the home’s features from the exterior to basement construction, framing, wiring, heating, and details for the interior design. Blueprints are drawn to scale so required materials can be ordered in the correct sizes and to ensure that overall dimensions and interior partitions can be easily understood.

 

In this lesson you will explore how to draw scale diagrams, of which blueprints are just one example. The scale diagrams will include representations of both two-dimensional and three-dimensional objects.

 

Lesson Question

 

In this lesson you will investigate the following question:

  • How is a scale diagram of a two- or three-dimensional object drawn?
