Where can i split the object? i have looked everwere but cant find it:S

split? what do you mean by split?

split the object so there are 2 instead of 1

use shift-D to duplicate objects. is that what you wanted?:eyebrowlift2:

In Edit mode press [P] on your keyboard. Choose one from the options:)

Its go to edit mode and prees “Y”

Yes, Y key “splits” but only selected vertices/faces.
Then you can use P key to make it a “real” object.

you can also do a rip with the V key.
