The weldment feature is not a feature in the same sense as a fillet or an extrude. Instead, it sets up a design functionality environment. The weldment feature designates the part as a weldment and enables the weldment environment.
The weldment feature:
- Activates the multibody environment by clearing the Merge result check box in the PropertyManagers of features that add material.
- Acts as a placeholder for common custom properties that are inherited by all cut list items.
