MAE 1351 Study Guide Question with Verified
Correct Answers
In the creation of solid models, computer-generated geometry was referred to as parts,
features, or objects; however, the objects that make up a system are referred to as
components
In assembly modeling, the copies of a component within the system are called
instances
A ___________is a grouping of components that serves a single purpose within the
overall assembly
subassembly
Why not just put multiple copies of the abutment part within the assembly? Why do
you have to learn about components and instances? Why are subassemblies that are
made up of instances and that are instances themselves important? The main reasons
for the changes are to
improve assembly modeling efficiency and to save computer storage space
improve assembly modeling efficiency and to save computer storage space __________
means that if you change the geometry of a part, the component and all instances of it
also will change by the same amount
associativity
Assembly models are easier to work with when they are organized in a logical manner.
An assembly is usually thought of as a composition of several smaller subassemblies,
, each of which may consist of other subassemblies or individual components. The
organization or structure of a system is referred to as its
hierarchy
The first thing you want to do after setting up your system hierarchy is to orient the
instances so they are properly located in space relative to one another. To do that, you
need to select one component to serve as the
base instance.
As with objects and features, the associations between components and subassemblies
are often called
parent-child relationships
hen creating parts, you used constraints to establish geometric and dimensional
relationships between 2-D entities or features. Thus, you constrained two lines to be
parallel or perpendicular to each other. Or you constrained the diameter of a circle to
be a specific size and its center to be located given distances from lines on the drawing
or from edges on an object. In assembly modeling, you can apply ____________ between
two 3-D instances so the instances maintain dimensional or geometric relationships with
respect to each other within the assembly
assembly constraints
Each time you bring an instance of a component into an assembly, you
introduce______________... Simultaneously, Each time you apply a constraint to the
assembly, you________________________
