Ch 9 Terms

Front 1

auxillery section

Back 1

a section that results from a cutting plane that is not parallel to any of the normal views

Front 2

broken out section

Back 2

a section that shows an object as it would look if a portion of it were removed by a cutting plane and then "broken off" to reveal the cut surface and insides

Front 3

conventional break

Back 3

a break that allows a uniform part of a very long object to be removed, making it easier to draw and understand

Front 4

crosshatching

Back 4

in architectural drafting, a full section that cuts across the entire structure to aid in interpreting the relationships of the important spaces

Front 5

cutting plane

Back 5

the plane through an object at which a section is created

Front 6

cutting plane line

Back 6

a line on a normal view that shows where the cutting plane passes through an object

Front 7

full section

Back 7

a sectional vew that shows an object as if it were cut completely apart from one end or side to the other

Front 8

half section

Back 8

section in which 1/4 of the original object has been cut away; 1/2 of a full section

Front 9

offset section

Back 9

a section in which the cutting plane is not a straight line but shifts at one or more places to show a detail or miss a part

Front 10

phantom section

Back 10

a hidden sectino used to show, in one view, the inside and outside of an object that is not completely symmetrical

Front 11

removed section

Back 11

a section that has been moved from its normal place to somehwere else on the drawing sheet

Front 12

revolved section

Back 12

.

Front 13

ribs

Back 13

a thin, flat part of an object used to strengthen or brace another part of the object

Front 14

section lining

Back 14

thin, evenly spaced lines that show a cut surface on a section. also called crosshatching

Front 15

webs

Back 15

a thin, flat part of an object used to strengthen or brace another part of the object

Front 16

general purpose section lining may also be used to designate what material?

Back 16

cast iron

Front 17

what type of line is used to show where a section is to be taken?

Back 17

section line

Front 18

when a cutting plane line passes through an entire view, a______section results.

Back 18

broken out section

Front 19

how are thin sections usually shown on a drawing?

Back 19

ribs

Front 20

if you were drawing a sectional view of a symmetrical object, what type of section would you use?

Back 20

half

Front 21

for drawings that contain several sections areas, why might it be faster to use a CAD program than to create the same drawing manually?

Back 21

cad allows you to show a cut surface by marking it with evenly spaced lines or patterns just as you would in tradition manual drafting.

Front 22

when one quarter of the object is cut away, a _____ section results.

Back 22

half section

Front 23

a revolved section is rotated___ degrees.

Back 23

90

Front 24

name four items that are generally not sectioned even when the cutting plane passes through their axis.

Back 24

shafts, bolts, pins, rivets

Front 25

a_____ section is used to show both inside and outside details of a nonsymetrical object.

Back 25

phantom

Front 26

what is the proper position for a removed section on a drawing?

Back 26

use bold letters to idenitfy a removed section and its corresponding cutting plane on the regular view

Front 27

give an example of the use of alternate section lines to clarify a drawing.

Back 27

by using ribs and webs. outlining the object.

Front 28

explain how a conventional break can make the detail easier to understand in the drawing of a very long object.

Back 28

shows the uniform break of the object.
