View Settings Dialog

In the View settings dialog window, you can set the display properties of the structures on the canvas.

The view settings dialog

Show chiral flag: The visibility of the Absolute chiral flag can be turned on/off.
Show valence errors: Marking of atoms with incorrect valence can be turned on/off.
Show lone pairs: The visibility of the lone pairs can be turned on/off.
Index atoms: When checked, the atom indices (the order of the atoms put on the canvas) are displayed.
Show atom maps: When this function is active, the atom map is visible.
Use CPK colors: When checked, the atoms are displayed colored according to the Corey-Pauling-Koltun convention. The two halves of a bond between two atoms will receive the color of the atom they are connected to.
Show carbon labels: When checked, the carbon atom labels become visible.
Implicit H: Use this option to show/hide hydrogens on atoms. The table below lists the options that are available.

Implicit H option	Description
Off	Disable implicit hydrogens on every atom.
Hetero	Display implicit hydrogens on heteroatoms.
Hetero and Terminal	Display implicit hydrogens on heteroatoms and terminal carbons. This is the default setting.
All	Display implicit hydrogens on every atom.

Display: You can choose between four display options: wireframe, ball and stick, stick, and spacefill. See the examples below.
