Keyboard Shortcut: No
This operator adds the Subdivision modifier to the selected objects or to all objects in the collection to which the selected objects belong. The number of subdivisions to add can be set, although it is important to be cautious as it can significantly increase the processor workload.
In addition, it can be set whether the modifier is applied to all objects in the collection or only to the selected ones with the "selected" property marked or unmarked. The "Apply Modifiers" operator definitively applies the previously assigned modifier.
Steps to follow:
Select the object(s) from the collection(s) where the objects will be subdivided.
Set the number of subdivisions to apply (be cautious as it can decrease performance).
Click on "Objects Subdivisions" to add the modifier.
Click on "Apply Modifiers" if you want to apply the subdivision definitively.
