2. Key takeaways

1

The center of mass is read relative to a coordinate system: select it in the mass properties window.

2

Collision detection stops the component on contact: this is what gives the required position.

3

An inserted subassembly is rigid by default: make it flexible so its parts move in the top-level assembly.

4

The Measure tool gives the angle between two edges without adding a dimension to the model.

Tip

Create the coordinate system as soon as the base component is placed: you will have it at hand for every center of mass question.

3. Do the exercise

Assemble a simple hinge:

  • a fixed bracket, an arm and a pin constrained with concentric and coincident mates
  • a two-part subassembly, inserted then made flexible
  • rotate the arm with collision detection and measure the resulting angle
✓To check: The arm stops on contact with the bracket, and the assembly's center of mass reads in your coordinate system.
