Assemblies & mates

Constrain parts into mechanisms.

Assembly

Overview

Assembly modeling combines parts with mates and constraints to represent how they fit and move together. It's where you check clearances, motion, and interference across a full product.

Step by step, with examples

  1. 1

    Components

    • Import the part files.
  2. 2

    Constraints

    • Coincident and concentric mates.
  3. 3

    Motion

    • Remove or keep degrees of freedom.
  4. 4

    Assembly

    • Check for interference.
    • Example: exploded view

Overview

Mates/joints define degrees of freedom between parts; bottom-up vs top-down assembly drives reuse and change management.

Common pitfalls

  • Over-constrained mates
  • Circular references
  • No skeleton for top-down
