Erasing existing Zstrokes..how?? (answered)

[Nancyan]

I’m trying to follow the following tutorial and I’m stuck here:

“Increase the ‘Draw Size’ to ‘100’ and erase all the existing ZSketch strokes so that only the original ZSpheres are visible.” Can someone please explain how one erases Zsketch strokes, please?

Hold down the ‘Alt’ key to erase.
