Perspective representation accurately depicts the spatial relationship of three-dimensional objects in a two-dimensional plane. In other words, a three-dimensional model on your screen appears more realistic when perspective is turned on. Alternatively, parallel lines in the model appear parallel when perspective is turned off. Perspective affects plots in all modules and is turned on by default.
To turn perspective on, select the icon located in the toolbar or select ViewPerspective from the main menu bar.
To turn perspective off, select the icon located in the toolbar or select ViewParallel from the main menu bar.
