auxillery section
|
a section that results from a cutting plane that is not parallel to any of the normal views
|
|
broken out section
|
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
|
|
conventional break
|
a break that allows a uniform part of a very long object to be removed, making it easier to draw and understand
|
|
crosshatching
|
in architectural drafting, a full section that cuts across the entire structure to aid in interpreting the relationships of the important spaces
|
|
cutting plane
|
the plane through an object at which a section is created
|
|
cutting plane line
|
a line on a normal view that shows where the cutting plane passes through an object
|
|
full section
|
a sectional vew that shows an object as if it were cut completely apart from one end or side to the other
|
|
half section
|
section in which 1/4 of the original object has been cut away; 1/2 of a full section
|
|
offset section
|
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
|
|
phantom section
|
a hidden sectino used to show, in one view, the inside and outside of an object that is not completely symmetrical
|
|
removed section
|
a section that has been moved from its normal place to somehwere else on the drawing sheet
|
|
revolved section
|
.
|
|
ribs
|
a thin, flat part of an object used to strengthen or brace another part of the object
|
|
section lining
|
thin, evenly spaced lines that show a cut surface on a section. also called crosshatching
|
|
webs
|
a thin, flat part of an object used to strengthen or brace another part of the object
|
|
general purpose section lining may also be used to designate what material?
|
cast iron
|
|
what type of line is used to show where a section is to be taken?
|
section line
|
|
when a cutting plane line passes through an entire view, a______section results.
|
broken out section
|
|
how are thin sections usually shown on a drawing?
|
ribs
|
|
if you were drawing a sectional view of a symmetrical object, what type of section would you use?
|
half
|
|
for drawings that contain several sections areas, why might it be faster to use a CAD program than to create the same drawing manually?
|
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.

|
half section
|
|
a revolved section is rotated___ degrees.
|
90

|
phantom
|
|
what is the proper position for a removed section on a drawing?
|
use bold letters to idenitfy a removed section and its corresponding cutting plane on the regular view
|
|
give an example of the use of alternate section lines to clarify a drawing.
|
by using ribs and webs. outlining the object.
|
|
explain how a conventional break can make the detail easier to understand in the drawing of a very long object.
|
shows the uniform break of the object.
