Canvas X Draw features additional page and layer controls at the bottom of the screen that can be used in addition to the Document Layout palette. Pages are called sheets, frames, or slides, depending on the type of document you are working in.
Click the New layer icon.
Another layer is added automatically to that sheet.
Open the Sheet menu and select the sheet that you want to view. You can also use the Page arrows to the left of the Sheet menu.
Use the Layer controls located to the right of the sheet & layer controls. If your document contains multiple layers, these controls scroll through the various layers.
