It is common to make changes when using freehand lines and shapes on the layout. You can use the eraser to erase freehand drawings from the canvas.
On the toolbar, click the "Eraser" icon, then click on the freehand drawing you want to remove.
The eraser removes only freehand drawings. To remove other objects, such as text, shapes, and comments, use the "Delete" icon in its contextual menu or select the object and press "Delete" on the keyboard.
