Geometric Projections

Read each question carefully and answer to the best of your ability. Show all your work for short answer questions.

1. Which type of projection shows an object from multiple views (top, front, side) to represent its true dimensions?

2. In an isometric drawing, what is the angle between the primary axes?

1. An   projection is a common method for drawing 3D objects on a 2D plane, where all three axes are equally foreshortened.

2. The three standard views in orthographic projection are the front view, the   view, and the side view.

1. Draw an isometric projection of a cube with side length 3 units. Label the dimensions.

2. Explain the difference between orthographic and isometric projection.

1. Orthographic projection accurately represents the depth of an object in a single view.

2. An isometric drawing preserves the true angles and lengths of all lines of an object.

Consider a rectangular prism with length 5 cm, width 3 cm, and height 2 cm. Sketch its orthographic projections (front, top, and right-side views).
