Object line
Hidden line
Construction line
Center line
Which line type is thick and dark and defines the visible edges of an object?
Construction line
Object line
Hidden line

Hidden lines are used to show:
Dimensions of the object
The center of a circle
Interior details not visible from outside
The cutting plane
Which line defines the center of arcs and circles?
Object line
Center line
Dimension line
Leader line
Center lines are usually:
Thicker than object lines
The same thickness as hidden lines
Half as thick as object lines
Drawn freehand
Section lines are used to:
Show hidden edges
Define where material is cut away
Show dimensions
Shorten long objects
Which line is freehand drawn and used to show a break in an object?
Long-break line
Hidden line
Short-break line
Extension line
Dimension lines are used to show:
Hidden details
Distances
Centers of circles
Object outlines
Arrows are drawn on which line type?
Center line
Dimension line
Construction line
Hidden line
Extension lines are used to:
Show object edges
Show cutting planes
Indicate where a dimension starts and stops
Show symmetry
Extension lines are usually placed how far from the object?
Touching the object
1/16 inch away from the object
1 inch away
Random distance
Which line is used to shorten very long objects?
Short-break line
Construction line
Long-break line
Leader line
Leader lines are mainly used to:
Show distances
Show dimensions of arcs, circles, or details
Show hidden edges
Show symmetry
Which line type has the highest precedence?
Center line
Hidden line
Object line
Construction line
When object lines and hidden lines overlap, which one is shown?
Hidden line

Object line
Section line
Hidden lines take precedence over:
Object lines
Cutting plane lines
Center lines
Section lines
Cutting plane lines take precedence over:
Hidden lines only
Center lines only
All other lines
Object lines only
Line conventions are mainly used in:
Artistic drawing
Freehand sketching only
Technical drawing
Painting
Which line type shows interior features using dashed lines?
Hidden line
Center line
Section line
Object line
The actual dimension value is usually placed:
At the end of extension lines
On object lines
In the middle of the dimension line
On hidden lines
An isometric drawing shows:
One view of an object
Two views of an object
Three dimensions in one view
Only hidden details
In isometric drawing, the angle between the horizontal axes is:
45°
60°
90°
120°
How many axes are used in isometric drawing?
One
Two
Three
Four
In isometric drawings, vertical lines are drawn:
Slanted
Horizontal
Vertical
Curved
The two horizontal axes in isometric drawing are usually drawn at:
30° to the horizontal
45° to the horizontal
60° to the vertical
90° to the vertical
Circles in isometric drawings appear as:
Perfect circles
Squares
Ellipses
Triangles
Isometric drawings are mainly used to:
Show hidden details clearly
Show realistic 3D views
Show only dimensions
Replace orthographic drawings
Measurements in isometric drawing are taken along:
Curved lines
Any direction
Isometric axes
Vertical lines only
Which tool is commonly used to draw isometric angles?
Compass
Protractor
T-square only
Freehand only
Isometric drawing is different from perspective drawing because it:
Uses vanishing points
Shows true lengths along axes
Distorts all dimensions
Uses only one axis
