In illustrator CC I want to center align multiple objects (such as crosses and circles) within a grid (for example 3 x 3) ie I want my artboard to look like this:
Should I use a grid for this? If so I have set up a grid (in Edit / preferences / Guides and grid) but I don't know how to center align a particular object (for example a green circle) to a particular grid square (for example center align a green circle to the top left grid square). Any ideas please?
