TESTED EXAM QUESTIONS VERIFIED ANSWERS
1) Component ✓ computer generated parts that
make up a system
2) Instances ✓ copies of a component w/in a
system(assembly)
3) An assembly cannot be nested ✓ False
inside an existing assembly; only
parts can.
4) What are the benefits of an ✓ - makes it easier to modify a part
assembly and propagate within the assembly
- saves computer memory
5) Associativity ✓ if the geometry of a part is
changed then the components and
, instances of that part will also
change by the same amount.
6) Parent-Child Relationships ✓ Associations between components
and subassemblies
Parent-subassembly
Child- component
7) base instance ✓ The instance chosen to orient
other instances in space relative to
itself
-they are stationary
8) What is the difference between ✓ Top -Down: breaking the assembly
Top-Down and Down-Up Hierarchy down to its components
Down-Up: Building the assembly
from its components to its
assembly final form
9) What purpose do reference planes ✓ they connect to base component
serve for an assembly and serve as the coordinate planes
for the space defined by the
system
10) Assembly Constraints ✓ dimensional and geometric
constraints between 2 3D
instances so the instances
maintain their
, geometric/dimensional
relationships w/respect to each
other w/in the assembly.
11) Degrees of Freedom ✓ a quantity used to represent the
location and orientation of a part in
3D space
12) I bring a part into an assembly in ✓ Align component origin with
SW and click the OK check mark assembly origin
in the top right. This will...
13) I bring a cube into an assembly ✓ 2
and mate-coincident one of its
edges to a fixed edge. It now has
these many DOFs:
14) I bring a cube into an assembly ✓ 3
and mate-coincident one of its
vertices to a fixed vertex. It now
has these many DOFs:
15) For every mate I apply, I reduce ✓ Depends on the mate
the DOF of the part by these
many:
