Alie cylindrical parts with concentric restraint
This section explains how to position cylindrical parts and cylindrical holes with different orientations using concentric alignment.
Methods:
- Using TriBall to manually align parts concentrically
→ No constraint applied - Using the [Concentric] constraint in the Assembly Constraints
→ Constraint applied
When using the [Concentric] constraint, moving one part will automatically move the constrained counterpart as well.

Constraints are also required when applying motion, such as in animations or Mechanism Mode.
Please refer to the video below.
