Final Advice on Working with Type in a Perspective Grid
Working with type in a perspective grid is significantly different from working with shapes. Until you select type with the Perspective Selection tool and move it, the type is not constrained by the perspective grid. The upside is that you can annotate illustrations that use a perspective grid, and the text you add doesn't adhere to the perspective grid. The downside is that it can be disorienting when one set of rules applies to shapes in the perspective grid, while another set of rules applies to type.
