Tips
- Save the design before you create a boss feature.
- Assign a plastic rule to the components that contain the bodies if you want the boss feature to inherit some of its dimensions from the plastic rule.
- Create a sketch on a parting plane between two bodies and place a point to center each boss feature.
- You can leave the sketch points unconstrained and drag them on the sketch plane to adjust the position of each boss, or constrain or dimension them in the sketch to define precise locations.
