Assembly &
Mechanism
Manage assemblies, verify component relationships, analyze interference, and simulate mechanism motion to identify problems during digital design before physical production.
When Parts Must Work Together, Assembly Design Goes Beyond Modeling Alone
Many products, machines, and mechanical systems consist of multiple components that need correct positions, relationships, and motion. Assembly design helps engineers check these within a digital engineering environment before building prototypes or manufacturing physical parts.
What Is Assembly Design?
Assembly design is the process of bringing multiple parts and components together in a CAD system to represent the structure of a product, machine, or mechanical system before it is built.
Engineers can define relationships between components to control position, orientation, and motion in line with the physical assembly.
Assembly Relationships
- Mate & Align
- Insert Connection
- Distance Constraint
- Angle Constraint
- Coordinate Relationship
- Pin & Slider Connection
- Mechanical Connection
From Part Design to Complete Assemblies
Creating assemblies helps engineering teams check whether independently designed components can actually be assembled and work together.
Part Modeling
Develop each component with the correct dimensions, features, and design intent.
Component Assembly
Add components to the assembly and define their positions, relationships, and constraints.
Design Verification
Check interference, clearances, and the correctness of the structure before manufacturing.
Motion Verification
Test mechanism motion and check the operating space of components in different positions.
Identify Assembly Problems Before Manufacturing Physical Parts
Interference or insufficient clearance discovered after machining or machine assembly can lead to substantial additional costs and engineering changes.
Interference Detection
Check for components that overlap or interfere within the assembly before manufacturing.
Clearance Analysis
Check the spacing between components to ensure sufficient room for actual operation.
Assembly Position
Verify that component positions and orientations match the design intent.
Tool Accessibility
Check space for tools, assembly, bolt tightening, and maintenance.
Component Movement
Check that moving parts can travel without colliding with other components.
Assembly Sequence
Evaluate the assembly sequence to ensure the product or machine can be physically assembled.
From Static Assemblies to Digital Mechanisms
For machines and products with moving parts, checking an assembly in just one position may not be enough.
Mechanism design helps define mechanical connections and test system motion, allowing engineers to check mechanisms before building physical prototypes.
Check Motion and Range of Movement
Motion simulation helps engineering teams understand system behavior and identify problems that may occur during actual operation.
Stroke Distance
Check the maximum and minimum travel distances of the mechanism.
Rotation Angle
Check the rotation angles of components and mechanical joints.
Mechanical Limit
Define motion limits that match the physical mechanism.
Collision During Motion
Check for collisions that may occur during motion.
Component Position
Analyze component positions at each stage of the cycle.
Mechanism Behavior
See how the mechanism behaves before building the physical system.
Manage Large Assemblies Systematically
When a machine or product has many components, the assembly structure directly affects how efficiently teams can open files, revise designs, and collaborate.
Dividing the model into subassemblies and organizing data appropriately helps reduce model complexity and makes large projects easier for engineering teams to manage.
Connect Assemblies to the Product Development Process
Assembly is more than a step for bringing parts together. It is a central point for verifying product architecture before passing information to engineering and manufacturing.
