Quiz 7: Sectional Views

A true projection of a sectional view always produces the actual shape of the object.

​Section lining should be parallel with the sides of the object to be section lined.

​A revolved section is the same as a rotated section.

​A removed section is very similar to a rotated section except that it is drawn away from the regular view.

​Hidden lines are usually not used in a section view.

​A removed section is sometimes drawn to a larger scale to illustrate and/or dimension a small feature.

​Half sections are best used when an object is not symmetrical.

Today, it is recommended to use the removed section rather than the revolved section.​

​If a cutting plane line passes lengthwise through the axis of a fastener or shaft, the fastener or shaft is not sectioned.

​If a cutting plane line passes perpendicularly through the axis of a fastener or shaft, the fastener or shaft is not sectioned.

​If there are two parts on the object, each part is sectioned with lines in different directions.

​The primary difference between a full section and an offset section is that the cutting plane is not straight in an offset section.

​In a true projection, a keyway is not shown in the hole.

​When a cutting plane line passes through a hole, it should be sectioned with lines in the opposite direction of the rest of the object.

​In a broken-out section, part of the cutting plane line is drawn freehand.

​The cutting plane is represented by a: A)​thin, black, solid line B)​thick, black, solid line C) ​thick, black, dashed line D) ​thick, black, dotted line

​Arrowheads at the ends of the cutting plane line indicate: A)​where the object is sliced by the cutting plane B)​direction of the cut C) ​what cutting plane line is to be used D) ​direction of sight

​Which of the following is not true of section lines. A)​They should be evenly spaced by eye. B)​They must be of uniform thickness. C) ​The average spacing used for most drawings is 3mm. D) ​They are generally drawn at 60 degrees to the horizon.

​In a half section, what percentage of the material is sectioned from the object? A)​75% B)​50% C) ​25% D) ​depends on the object

​This type of section is used to make a particular feature of an object easier to understand. A)​rotated B)​offset C) ​broken-out D) ​removed

​If an object has a part to be sectioned that is not true size, this type of sectional view must be used. A)​offset B)​auxiliary view C) ​removed D) ​partial

​This type of section illustrates both the exterior and interior of the object. A)​half B)​offset C) ​removed D) ​broken-out

​This is not included on an assembly section drawing. A)​legend B)​parts list C) ​notes D) ​parts

​This practice is used when holes located around a bolt circle are not aligned with the cutting plane line. A)​alternate section lining B)​aligning of sections C) ​aligning of features D) ​rotating section views

​To indicate that a sectioned part is made of brass, it is best to: A)​add a note to the drawing B)​label the part C) ​use appropriate section lines D) ​add a note in the title block

​Which of the following is not a list of types of sectional views? A)​full, half, offset B)​front, back, profile C) ​broken-out, revolved, removed D) ​thinwall, auxiliary, assembly

​Which of the following is not true regarding alternate section lining? A)​It is a combination of true projection and correct representation. B)​Over the rib or web section, every other section line is drawn. C) ​The rib or web section is not lined. D) ​The actual shape is indicated by hidden lines.

​What must be done if a removed section must be placed on another page other than the page on which the cutting plane line is placed? A)​The page where the removed section is located must refer back to the page from where it was taken. B)​A page number cross reference must be given as to where the removed section may be found. C) ​both A and B D) ​none of the above

​What must be included for each part in an assembly section? A)​name of the part B)​part number of plan number C) ​quantity required to complete one assembly D) ​all of the above

​A section view usually shows _____ details. A)​exterior B)​interior C) ​profile D) ​foreshortened

​The direction of sight of a section is indicated by the: A)​viewing direction of the section B)​arrows at the end of the cutting plane line C) ​offset section in the section D) ​dashed lines on the section

​The "general" symbol used for sectioning is actually the _____ symbol. A)​cast iron B)​steel C) ​brass D) ​wood

​A(n) _____ is a section view drawing in which the cutting plane line is bent. A)​full section B)​revolved section C) ​offset section D) ​broken-out section

​Cutting plane lines compared to section lines are: A)​dashed B)​thinner C) ​the same size

​The lines in a section view used to show where the material is cut, and in some cases to identify the type of material, are called: A)​cutting lines B)​section lines C) ​object lines D) ​hidden lines
