What is a scale drawing and why is it used?

• A scale drawing is a proportional representation of an object or area, used for accurate visualization and planning.

• A scale drawing is used only for artistic purposes.

• A scale drawing is a detailed painting of an object.

• A scale drawing is a random sketch with no measurements.

How do you calculate the scale factor for a drawing?

• Scale Factor = Actual Size - Drawing Size

• Scale Factor = Actual Size / Drawing Size

• Scale Factor = Actual Size + Drawing Size

• Scale Factor = Drawing Size / Actual Size

What are the key features of isometric drawings?

• Unequal scaling for dimensions

• Only represents two dimensions in three dimensions

• Key features of isometric drawings include 30-degree angles, equal scaling, and representation of three dimensions in two dimensions.

• Use of 45-degree angles

How do you create an isometric drawing of a cube?

• Start with a circle and add lines for the cube's edges.

• Use only horizontal lines to create the cube.

• Draw a square and shade it to represent depth.

• Draw a vertical line, then two 30-degree lines for depth and width, and connect to form the cube.

What distinguishes oblique drawing from other types of drawing?

• Oblique drawing distorts dimensions to create a 3D effect.

• Oblique drawing uses only vertical lines for depth.

• Oblique drawing represents objects in a completely flat manner.

• Oblique drawing uses angled projection for depth while keeping true dimensions in the front view.

What are the two main types of oblique drawing?

• Isometric and Perspective drawings

• Linear and Circular drawings

• Cavalier and Cabinet oblique drawings

• Orthographic and Axonometric drawings

How do you represent depth in an oblique drawing?

• Depth is represented by using straight vertical lines.

• Depth is shown by shading the object darker.

• Depth in an oblique drawing is represented by using angled lines to depict the object's depth.

• Depth is indicated by using dotted lines.

What is the purpose of perspective drawing?

• To simplify complex shapes in drawings.

• To enhance color vibrancy in illustrations.

• To create abstract art without depth.

• To create the illusion of depth and realism in drawings.

What are the three types of perspective drawing?

• Perspective, Orthographic, and Planar drawing

• One-point, Two-point, and Three-point perspective.

• Isometric, Axonometric, and Oblique perspective

• Linear, Curvilinear, and Aerial perspective

How does one-point perspective differ from two-point perspective?

• One-point perspective has one vanishing point, while two-point perspective has two vanishing points.

• One-point perspective is used for drawing circles.

• One-point perspective uses three vanishing points.

• Two-point perspective has one vanishing point.
