Easy question – how to I clear a canvas or start a new one?
Thanks for asking! Try tapping the little gray arrow in the bottom left corner of the canvas – it should take you to a menu where you can add new sketches (+ icon).
To clear a canvas, you can select everything by tapping and holding on each object (there’s also a Select > All option in the menu that appears), and then tapping Delete in the menu.
Hope this helps!
Ok. Figured out how to make a new canvas but cannot delete them.
Thank you. Found the new canvas area. How do I delete a full canvas? Can it be deleted on them at same page?
Yes, you can tap and hold on a thumbnail to show the X button, which will delete that sketch.
Got it. Light touch not a long hard touch. Thanks!
