What is perspective drawing used for in engineering and design?
Representing 3D objects on a 2D surface using visual depth and proportion.
What happens to object size in perspective drawing as it moves further away?
It appears smaller due to proportional reduction.
When is the true shape of an object visible in perspective drawing?
Only when viewed at right angles to the line of sight.
What is a vanishing point?
A point on the horizon line where parallel lines appear to converge.
What does the “eye level” refer to in perspective drawing?
The horizontal line at the viewer’s eye height, defining the horizon line.
What are the characteristics of a single-point perspective?
One vanishing point; used for front-on views like room interiors and roads.
What are the characteristics of two-point perspective?
Two vanishing points; used to show objects at an angle for better spatial depth.
What is a key advantage of oblique sketches?
One face is shown in true shape.
What is the disadvantage of oblique drawings?
They are not photorealistic.
What is a key feature of isometric drawings?
Easy object visualization, but not a true face view.
What is the strength of perspective sketches?
Realistic 3D appearance.
What is a downside of perspective sketches?
Faces may appear distorted.
What is the benefit of multi-view sketches?
Accurate representation of each object face.
What are examples of advanced projection types?
Axonometric, Isometric, Cavalier, Cabinet projections.
