30-60 triangle with a 45° triangle
Two 45° triangles
Two 30-60 triangles
Protractor and scale

Which line type has the highest precedence when lines coincide?
Visible (object)
Hidden
Center
Phantom
Centerlines are used to indicate:
Axes of symmetry and hole centers
Visible outlines
Hidden edges
Material types
A phantom line is best used to show:
Alternate positions of a part
A hidden interior edge
The edge of a slot
A break in a long object
Hidden lines should be drawn:
Thin with short dashes
Thick solid
Thin long–short–short pattern
Thin dot-dash pattern
Section lines should be:
Thin and evenly spaced
Thick and random
Drawn as centerlines
Drawn thicker than visible lines
Extension lines:
Do not touch the object and continue past the dimension line
Are thick and dark
Always end with dots
Are the same as visible lines
Dimension lines usually terminate with:
Arrowheads
Dots
Squares
Nothing
In third-angle projection, the top view is located:
Above the front view
Below the front view
Left of the front view
Right of the front view
In third-angle projection, the right-side view is located:
To the right of the front view
To the left of the front view
Above the top view
Below the front view
A principal plane appears as:
True size in one principal view
Foreshortened in all views
Edge view in all views
True size in all three views
An inclined plane appears:
As an edge view in one principal view and foreshortened in the other two
True size in all three views
Foreshortened in all three views
As edge view in all three views
An oblique surface appears:
Foreshortened in all three principal views
True size in top view
Edge view in front view
True size in right-side view
Tangent edges (smooth transitions between curved and flat faces) are:
Usually omitted unless needed for clarity
Always shown as visible lines
Always shown as centerlines
Always shown as hidden lines
Mechanical/engineering scale is most appropriate for:
Machine parts in decimal/fractional inches

Which sheet is the smallest standard engineering sheet size?
A (8.5×11)
B (11×17)
C (17×22)
D (22×34)
Standard drafting lettering is:
Uppercase, sans-serif, unidirectional
Mixed case serif
Lowercase cursive
Italic serif
Good view layout includes:
Even spacing and room for dimensions
Random spacing
Views touching the border
Dimensions over hatching
Isometric drawings should:
Measure only along the isometric axes
Measure anywhere on the face
Use 45° axes
Show dimensions at 60°
When drawing an isometric, the common axis angles from horizontal are:
≈30° right and left
15° and 45°
0° and 90°
60° and 120°
Section lining for adjacent parts should:
Differ by angle or spacing to distinguish parts
Always be parallel and identical
Use centerlines
Be thicker than visible lines
Cutting-plane lines are usually drawn:
Thick with alternating long and short dashes
Thin solid
As centerlines
As hidden lines
A good drafting technique is to:
Incline the pencil in the direction of the stroke
Erase with your hand
Darken lines from bottom to top only
Draw all construction lines heavy
Construction lines should be:
Light and thin
Thick and dark
As heavy as visible lines
Erased immediately
To bisect an angle mechanically, the best tool combination is:
Compass and straightedge/triangle
Protractor alone
French curve
Scale and dividers only
Which tool will *not* help you draw a precise 60° line directly?
45° triangle
30-60 triangle
Two triangles combined
Protractor
To lay out a 2.500" circle, you would set the compass to:
1.250" radius
2.500" radius
5.000" radius
0.250" radius
Dividers are most accurate when:
Stepping off along a straight line
Dragging arcs across paper
Used as a compass
Used to erase pencil
If a cylindrical hole appears as a rectangle in the front view, the top view will show it as:
A circle
A hidden line only
Another rectangle
A centerline only
When a hole axis is shown, the correct linetype is:
Centerline
Hidden
Visible
Phantom
