Note: if the screen is narrow, this may be a submenu in the Input menu.
Crystal Edges - This controls the display attributes (color, etc.) of the edges defining the exterior crystal shape, if present.
Perspective - Controls drawing in perspective versus straight projection.
Stereopairs - Controls automatic drawing of stereopairs.
Rims - Controls presence or absence of rims on atoms and bonds and edges on polyhedra.
Linewidths - Controls widths of lines used as edges, etc.
Shading - Controls three-dimensional shading.
Background Color - Controls background color (ignored for b/w display or output).
Crystal Axes - Controls display of crystal or structure axes.
Unit Cell - Controls display of the unit cell, which may be drawn as edges or solid (translucent) faces.
Ellipsoid Parameters - Controls the drawing of ellipsoids and stick bonds in the Thermal Ellipsoids and 3D Drawing modes.
3D Parameters - A pop-up submenu, controlling aspects of the 3D Display mode.
---- General - Some overall parameters.
---- Lighting - Number, direction and/or location of lights.
---- Material - The way the atoms, bonds and polyhedra reflect or emit light.
---- Fog (Fading) - Aids the illusion of depth.
---- Polyhedra - Some aspects of polyhedra specific to the 3D drawing mode.
PDB (Protein) Display - A pop-up submenu (no dialogs), controlling which atoms are plotting in Protein Data Bank structures.

Initial Orientation - Controls the orientation which can be imposed after calculation and before first viewing.
Scaling - Controls scaling modes and factors.
Centering and Displacements - Controls displacements and automatic centering of the image.
Calculation Output - Controls the listing of the analytical results of the calculations such as atom locations, bonds, etc.
Atom/Bond Plot States - Allows changing the plotting or non-plotting status of generated atoms and intermolecular bonds.
