Correct Answers
What are some problems with pictorials? - Correct Answer the distortion of angles, the
distortion of true lengths, the distortion of Internal measurements, the distortion of
curves
Then the general rule for presenting the object becomes: - Correct Answer "Start with
the preferred configuration; then add or subtract whatever views are necessary to best
show all of the geometry."
An axonometric drawing refers to three types of pictorial drawings: - Correct Answer
isometric, dimetric, and trimetric drawings
The absence of a second arrow is an indication that the cutting plane line is for a
____________ ____________ - Correct Answer half section
Try drawing freehand a vertical line 5 inches long. Which direction did you follow? -
Correct Answer top to bottom

Answer No, pictorials are for informal communication only
A fundamental problem with pictorials is that: - Correct Answer Angles and distances
cannot be read directly
SW can display an object in the following views: - Correct Answer isometric,
perspective
My drawing axes for a 3D view are set such that the angles between them are as
follows: 240,30,90 with one of the lines horizontal. The view is: - Correct Answer
Cavalier
The same orthographic projection may be obtained from two different parts. True? -
Correct Answer Yes; two orthographic projections of completely different objects may
look identical
A part may be properly represented on an engineering drawing with as few views as... -
Correct Answer one
The US standard for multiview orthographic projection is: - Correct Answer Third angle
Germany - Correct Answer First angle
, section lines are used to.... - Correct Answer improve the clarity of a section view by
indicating the portions of the part that had been solid at the location it was hypothetically
cut
T/F the line thickness for the section line pattern is usually thicker than the part edges -
Correct Answer false
It is okay if the section line pattern is parallel or perpendicular to major features egdes -
Correct Answer no, this can cause confusion
T/F Offset sections can be considered modifications of full sections - Correct Answer
true
An offset section... - Correct Answer allows multiple features, which normally require
multiple section views, to be captured on a single view
T/F Half sections do not save space or labor on an engineering drawing, especially for
symmetrical parts - Correct Answer false
When an object is symmetrical about a plane or an axis, it is not acceptable to present
the object partially in its original state and partially in a sectioned state on the same
orthogonal view - Correct Answer false, it is acceptable
C size - Correct Answer plotter
If one chooses a larger sheet size, the text must also be printed larger. True? - Correct
Answer No; lettering size should be the same no matter how small or large the sheet of
paper
The revision block in an engineering drawing contains... - Correct Answer A historical
record of changes made to a drawing
Engineering drawings should always have a front, top and right view. True? - Correct
Answer no
A removed section - Correct Answer offers the convenience of showing only the new
surfaces created by a cutting plane, without the complexity of showing the remaining
surfaces
T/F the cutting plane should be parallel to one of the principal views or perpendicular to
the major *surfaces* of the part where the cut is made in order to reveal its true sizes -
Correct Answer true
There is no need for view alignment for the removed section, although... - Correct
Answer its orientation must still follow the rules of multiview presentation and the
section view should be located near the cutting plane line
