Chapter 15: Modifying 3D Objects

Isometric Assembly Drawings

1.
Isometric assembly drawings
A)are usually created using 2D techniques.
B)are not necessary when solid models exist.
C)show an isometric view of the parts that make up a component.
D)consist of a collection of individual drawings, one drawing per part in the assembly.
2.
The small notes on an assembly drawing that indicate find numbers associated with the parts list are known as
A)bubbles.
B)balloons.
C)notes.
D)clouds.
3.
Assembly drawings include
A)complete dimensions for all of the parts.
B)dimensions for the most important part only.
C)only the dimensions that are needed to assemble the components.
D)no dimensions.
4.
On assembly drawings, hidden lines are
A)converted to continuous lines so that they show up better.
B)shown exactly as they would appear on a 2D drawing.
C)shown only when necessary to understand the assembly.
D)not used.
5.
All of the objects in an assembly drawing
A)are shown complete with dimensions and manufacturing notes.
B)are shown with manufacturing notes but without dimensions.
C)have separate detail drawings to specify dimensions and manufacturing notes.
D)have an associated parts list on the assembly drawing.
6.
An exploded assembly drawing is one in which
A)the parts have been separated so that you can see how they are connected.
B)the objects in the assembly have been exploded into their component parts.
C)manufacturing notes have been added.
D)the parts are shown in their completely assembled form.
7.
Exploded assembly drawings are used when
A)the drawing will be used by both the engineering department and the manufacturing department.
B)a pictorial view is needed to obtain approval from management or a client.
C)all of the parts are similar in size and shape.
D)some of the parts would be obstructed from view by other parts in an unexploded assembly drawing.
8.
All of the following are advantages of using a solid model to create an assembly drawing except that the drafter
A)does not have to create a new, separate view for the isometric drawing.
B)can use the solid model to generate 2D detail drawings.
C)does not have to be familiar with the organization of 2D drawing layouts.
D)can make a change in one place only, instead of having to change multiple documents.
9.
The first step in creating a solid model for an exploded assembly drawing is to create
A)all of the components to be assembled.
B)a surface model to show what the finished assembly will look like.
C)2D detail drawings to specify the dimensions of the parts.
D)a new layout to display the drawing.
10.
To position the components correctly in relation to each other, you can use any of the following commands except
A)ROTATE3D.
B)MOVE.
C)BLOCK.
D)ALIGN.
