To change the rulers’ zero points The default zero point for each ruler is at the top-left corner of the illustration area. To change the zero point, drag from the intersection of the rulers. As you drag the zero point, intersecting lines follow the pointer. To return the rulers to the default zero point, click the box where the rulers intersect. To use ‘tear-off’ rulers When rulers are displayed, you can move a copy of a ruler into the layout area to measure specific areas of an illustration. When you tear off a ruler and move it, Canvas takes a snapshot of the ruler and pastes it into the document as a paint object. A tear-off ruler isn’t active like the rulers displayed at the window edges. To place a tear-off ruler in a document:  Point to the ruler you want to tear off, press Option (Mac) or Alt (Windows) and drag a copy of the ruler into the document. Using the alignment grid You can display a grid of vertical and horizontal lines to aid in posi- tioning objects in a document. You can also turn on the snap-to-grid feature to make Canvas snap objects into alignment with the grid when you drag near a grid line. When snap-to-grid is active, the pointer movements snap to the grid according to the settings in the Grids dialog box. To display grid lines on screen:  Choose Layout > Display > Show Grids. To turn off grids, choose Layout > Display > Hide Grids. To turn on snap-to-grid:  Choose Layout > Snap To > Grid. Choose the command again to turn off snap-to-grid. To temporarily override the grid constraint:  Press Tab as you create, resize, or move objects.
