Assembly Modeling MCQs

What is assembly modeling in CAD?

• Creating individual parts

• Assembling physical components

• Designing a collection of parts and their relationships

• Manufacturing individual components

Which method is typically used in CAD software to establish relationships between parts in an assembly?

• Boolean operations

• Geometric constraints

• FEA analysis

• Surface meshing

What is the primary purpose of using constraints in an assembly model?

• To create a visual representation of the model

• To define the relative motion and positioning of components

• To apply material properties

• To run a stress analysis

What is a "bottom-up" assembly modeling approach?

• Creating the assembly first, then designing individual parts

• Designing individual parts and assembling them afterward

• Optimizing assembly for manufacturing

• Importing components from a third-party library

In a "top-down" assembly modeling approach, parts are usually designed:

• Independently, outside the assembly

• Within the context of the assembly

• Using standard templates

• As standalone prototypes

Which of the following constraints allows rotation of one part relative to another?

• Fixed constraint

• Mate constraint

• Revolute constraint

• Parallel constraint

What is interference checking in assembly modeling?

• Determining material overlap in an assembly

• Ensuring parts are geometrically constrained

• Testing dynamic motion of parts

• Assigning material properties

Which CAD tool feature is often used for simulating the motion of an assembly?

• Sketch module

• Surface modeling

• Kinematic analysis

• Extrusion module

What is the significance of "degrees of freedom" (DOF) in assembly modeling?

• It represents the thermal properties of a material

• It indicates how freely a part can move in the assembly

• It defines the electrical conductivity of the assembly

• It measures the strength of the materials

Which of the following is NOT a common type of assembly modeling constraint?

• Mate

• Align

• Coefficient of friction

• Tangent
