__________is the 'Universal Language of Industry'.
Drafting
One difference between multiview drawings and pictorial drawings is that pictorials show an object as it appears to the human eye. The other difference is that pictorials give __________.
perspective
__________ are imaginary perpendicular lines, drawn from all points on the edges or contours of the object, to the plane of projection.
Projector lines
The plane of projection on which the top view is projected is called the __________ plane.
horizontal
Objects have three principal dimensions- height, width, and __________.
depth
When using the "Glass Box" idea of viewing the various sides of an object, the __________ views all line up vertically and are the same width.
front, top, and bottom
Two or more circles, of different diameters, that have the same center are called __________ circles.
Concentric
A __________ section view is a complete or partial view moved to another place on the sheet so that it is no longer in direct projection with any other view, and is always identified by a viewing-plane line which is 'labeled' the same as the view-such as: "View A-A".
removed
A surface may be frontal, horizontal, or profile, according to the plane of projection to which it is __________.
parallel
A/An __________ surface is a plane surface that is perpendicular to one plane of projection, but angled to adjacent planes. It shows as a straight line on the plane to which it is perpendicular, and as a foreshortened surface on the other planes.
inclined
If a cylinder is cut by an inclined plane, in the auxiliary view of that surface, it will show as a/an __________.
ellipse
A slightly rounded interior corner is called a/an __________.
fillet
The two types of dimensions are __________.
size and location
__________ divisions and metric units are now most commonly used throughout industry.
Decimal
A/An __________ is a thin line, with arrows, that shows where a measurement begins and ends, or the size of an angle.
dimension line
A/An __________ can be drawn at virtually any angle, as long as, when used with circles or arcs, if extended, it would pass through the center point of the circle or arc.
__________ dimensioning is when both decimal inch, and metric measurements are given.
Dual
In the __________ method of placing dimensions on drawings, all the dimensions are arranged so as to read from the bottom of the page.
unidirectional
Arc dimensions are always preceded by the __________.
__________ are points, lines, and surfaces that are assumed to be exact.
Datum
Tolerance- equals the difference between __________.
exact dimension and actual size
Holes on an object may be located by means of __________.
The sectional view obtained by passing a cutting-plane fully through the object is called a __________ section.
half
__________- thin, parallel lines, evenly spaced apart, represent those portions of an object that have been in actual contact with the cutting-plane.
Hatching
As a rule, what type of line IS NOT used in Section Views?
HIdden lines
According to the alphabet-of-lines, a thin line made up of one long and one short dash, repeated over and over is a/an __________ line.
center
In order to show internal features that do not lie in a straight line, a/an __________ is often employed.
offset section
The __________ dimension shown in an auxiliary view is the one NOT shown in the adjacent view.
principal
Auxiliary view have all of the following uses EXCEPT
1. True length of line
2. Point view of line
3. Edge view of plane
4. True size of plane
The purpose of a//an __________ view is to show an inclined surface in itss true size and shape.
auxiliary
The term __________ simply means "equal angle".
congruent
This form of pictorial drawing shows surfaces which are parallel to the frontal plane to be true size and shape. __________
orthographic
Isometric axes are always drawn at an angle of __________ degrees to each other.
120 degrees out
__________ in isometric drawings can only be drawn by locating their end points, and then connecting those end points.
Angles and isometric lines
The technique we use to draw ancs/circles in isometric is called the __________.
far center ellipse
An oblique drawing made with its depth axis equal to one-half its true distance is known as a __________ oblique.
cabinet
Perspective projection requires __________ view/views in order to construct the perspective view.
3 views
When making a 2-pt. perspective drawing, the location of the __________ will determine whether you will have a "bird's eye" view, "worm's eye" view, or normal view.
horizon
__________drawings are the most "realistic" appearing pictorial drawings.
Perspective
A measurement of 1 inch converts to how many millimeters?
25.4mm
