PLTW IED Isometric Sketching Quiz

What is isometric sketching?

• Method of creating a 3D representation of an object on a 2D surface.

• A process of creating a 2D sketch of an object from multiple perspectives.

• A technique used to create 2D drawings of 3D objects.

• A method of creating a 2D representation of an object on a 3D surface.

Name one technique used in isometric sketching.

• Orthographic projection

• Perspective drawing

Provide an example of an isometric sketch.

• A cylinder.

• A sphere.

• A cube

• A pyramid.

Is isometric sketching a 2D or 3D drawing technique?

• 3D

• 2D

• 4D

• 5D

What are the three axes used in isometric sketching?

• x-axis, y-axis, z-axis

• a-axis

• b-axis

• c-axis

How does isometric sketching differ from perspective drawing?

• Isometric sketching is done freehand, while perspective drawing requires the use of a ruler.

• Isometric sketching uses parallel lines, while perspective drawing uses converging lines.

• Isometric sketching is used for 2D drawings, while perspective drawing is used for 3D drawings.

• Isometric sketching uses curved lines, while perspective drawing uses straight lines.

What is the purpose of isometric sketching in engineering design?

• To determine the material properties of an object in engineering design.

• To calculate the weight of an object in engineering design.

• To create a three-dimensional representation of an object in engineering design.

• To create a two-dimensional representation of an object in engineering design.

Explain the concept of foreshortening in isometric sketching.

• Foreshortening is the technique of representing objects in their actual size and proportions in isometric sketching.

• Foreshortening is the technique of representing objects closer to the viewer as the same size as objects farther away in isometric sketching.

• Foreshortening is the technique of representing objects closer to the viewer as larger and objects farther away as smaller in isometric sketching.

• Foreshortening is the technique of representing objects closer to the viewer as smaller and objects farther away as larger in isometric sketching.
