The Flatten operation is used to merge drawing objects and brush strokes into a single layer. If you draw new lines to fix a drawing or line with many brush strokes, it can be useful to flatten them all into a single shape. By default, lines are drawn one on top of each other. If you intend to repaint the lines or modify their shape, it will be easier if they are flattened.
- In the Tools toolbar, select the Select tool.
- In the
Camera orDrawing view, select the drawing strokes you want to flatten.
- Select Drawing > Optimize > Flatten or press Alt + Shift + F. You can also press the Flatten button in the Tool Properties view.
