Propagate Slots
When creating a tab and slot feature in an assembly component, you can propagate the slots to other instances of the same component in the assembly.
If an assembly has a component with a tab previously created with the Tab and Slot tool, you can propagate slots for that tab to other instances of the component in the assembly as well.
For example, if you have an assembly with multiple instances of a part with a tab, you can propagate slots for the corresponding instances.
Slots propagate only when the tab component intersects with the slot component.
If you pattern or mirror a component with a tab, you can select Propagate Slots in the PropertyManager to apply slots to intersecting components in the assembly.
