Abstract
Methods and apparatus provide for a perspective guide. The perspective guide identifies a first object displayed on a graphical user interface rendered on a display device. An edge of the first object includes an anchor point. The anchor point is positioned on a vector that extends from the vanishing point towards the anchor point, where the predefined vanishing point is placed in a perspective drawing on the graphical user interface. The perspective guide associates a graphical pointer to the anchor point, and the perspective guide draws a new object relative to the anchor point on the graphical user interface while maintaining at least one edge of the new object in forced perspective alignment with the vector.
