Snap to a Grid or Guide in InDesign CS5
With grids and guides, you can align objects precisely in InDesign Creative Suite 5. When you move an object close to a grid or guide, the object snaps to it, aligning it precisely.
Snap objects to grids or guides
You can have elements on the page snap to a grid or a guide. Grid or guide snapping is useful so that you don’t have to eyeball the alignment of several elements to one another, because they’re precisely aligned to a grid or guide.
To make sure that the snap settings are enabled, choose View→Grids & Guides→Snap to Document Grid or View→Grids & Guides→Snap to Guides.
Then drag an object towards a grid or guide to snap it (align it) to the grid or guide.
Align objects with Smart Guides
Give yourself an added hand when aligning objects on the InDesign page with Smart Guides. Illustrator and Photoshop users may be familiar with these interactive guides, but if you’re not, read on to discover how you can take advantage of them.
Smart Guides help you align objects to each other. You can experiment with this new feature by creating two objects in an InDesign document. It doesn’t matter which object or shape — any will do!
With the Selection tool, click and drag one object in a circular motion around the other. You’ll notice guides appear and disappear, indicating when the objects are aligned either on the top, center, or bottom of the other object.
As a default, pink guides appear when you align an object with the center of the page.
You can see a print preview of your document by clicking the Preview Mode button at the bottom of the Tools panel. When you click this button, all object bounding boxes, guides, and the grid disappear.
