This block is used in most projects involving the pen, as clearing the screen once the project starts would be a main priority.
Some common uses for the Erase All block are:
- Clearing the screen in a paint program
when this sprite clicked switch costume to [pressed v] erase all wait until <not <mouse down?>> switch costume to [not pressed v]
- Resetting the penning ground in a pattern maker
wait until <(dots made) > > set [dots made v] to  erase all
- Removing stamps in a maze generator or something similar
when I receive [next maze v] erase all broadcast [generate v]
- Clearing the screen to draw the next frame in a pen animation
when gf clicked forever draw end define draw erase all . . .
