16. What is Technical drawing?
17. What is Artistic drawing?
18. What is the purpose of an isometric drawing?
Isometric drawings are used to represent 3D objects in 2D space, allowing for a better understanding of the object's dimensions.
19. Which tool is commonly used for creating accurate circles in technical drawings?
A compass is a drawing tool that allows for the creation of accurate circles and arcs in technical drawings.
20. In which type of projection are objects drawn in true size as seen from one side only?
Orthographic projection displays objects in true size and shape as seen from one side only, commonly used in technical drawings to show multiple views of an object.
21. Which type of line is used to indicate where an object is cut in a sectional view?
Cutting plane lines are used in technical drawings to show where an object is cut in a sectional view, indicating the portion of the object that is being shown.
22. What do construction lines in a technical drawing represent?
Construction lines are used as reference guides in technical drawings, helping to align and construct the final drawing accurately.
23. Which type of projection shows objects as they appear to the eye with depth and perspective?
Perspective projection shows objects with depth and perspective as they appear to the eye, often used in artistic or architectural drawings for a realistic representation.
24. What does a symbol of a triangle on a technical drawing represent?
The symbol of a triangle on a technical drawing represents a centerline, used to indicate the center of symmetry or alignment of an object.
25. Which type of line is used to indicate an edge of an object that is not visible in a drawing?
Hidden lines are used to represent edges of objects that are not visible in a particular view in technical drawings, ensuring clarity and understanding of the object.
26. What do irregular lines on a technical drawing represent?
Irregular lines are not a standard representation in technical drawings and should not be used as final drawing lines, dimension lines, or section lines.
27. Which type of projection shows the object by rotating it in 3D space with the front view shown parallel to the picture plane?
Cavalier projection rotates the object in 3D space with the front view parallel to the picture plane, providing a distorted representation of the object's depth compared to other projections.
28. Which type of line is used to indicate the outline of an object in a technical drawing?
Visible lines are used to represent the outline or edges of an object in a technical drawing, ensuring clarity and understanding of the object's shape.
29. What do arrowheads on dimension lines in a technical drawing represent?
Arrowheads on dimension lines indicate the direction in which the dimensions are being measured, providing clear and accurate information about the size of the object.
30. Which type of line is used to show dimensions and sizes in a technical drawing?
Dimension lines are used to indicate the sizes and measurements of objects in a technical drawing, helping to understand the scale and proportions of the object.
31. What is the purpose of a leader line in a technical drawing?
Leader lines are used to point to specific features or details on a technical drawing, guiding the viewer's attention and providing additional information about the object.
32. Which type of projection shows the object by projecting points on the object to points on a plane?
Pictorial projection shows the object by projecting points on the object to points on a plane, creating a three-dimensional representation of the object in a 2D space.
33. What does a symbol of two parallel lines on a technical drawing represent?
The symbol of two parallel lines on a technical drawing represents a hidden line, indicating edges of objects that are not visible in a particular view.
34. Which type of line is used to show the imaginary line of symmetry in an object?
Centerlines are used to represent the imaginary line of symmetry in an object, helping to align and understand the object's structure in technical drawings.
35. What do a series of closely spaced short dashes on a technical drawing represent?
A series of closely spaced short dashes represent a phantom line in technical drawings, indicating alternate positions or movement of an object.
36. Which type of line is used to separate two adjacent parts in a technical drawing when there is no physical gap between them?
Phantom lines are used to separate two adjacent parts in a technical drawing when there is no physical gap between them, indicating a break or discontinuity in the object.
37. What do a series of long dashes alternating with two short dashes on a technical drawing represent?
A series of long dashes alternating with two short dashes represent a centerline in technical drawings, indicating the line of symmetry or alignment of an object.
38. Which type of projection shows objects by projecting points on the object to points on a plane using parallel, inclined, or curved lines?
Pictorial projection shows objects by projecting points on the object to points on a plane using parallel, inclined, or curved lines, creating a visual representation of the object in 2D space.
