The following sites as well as the in-class demo will help to “gain perspective.” And, nothing helps more than to practice and play the “game” of perspective so that it can be internalized and become somewhat automatic as you translate your vision of 3 dimensional space to a flat picture plane. Once you understand, you can use perspective naturally without thinking it through. And, as you become fluent in the language of this tool, you can depart from it for intentional expressive effect.

And for drawing slopes and tilting boxes (see p. 110 on):
Always, it is practice that will secure your understanding and allow you to draw gesturally with a confident sense of form and space.
