Drawing Captions and Atom Labels

---

Creating Text

---

ChemDraw enables you to create the following types of text:

• Caption text-Create annotations, chemical names, chemical formulas, page titles, and information in tables.

• Atom label text-Identify atoms and substructures by their chemical symbols and formulas.

The behavior of atom labels is controlled by the "Automatic Atom Labels" checkbox on the "General" tab of the Preferences dialog box. This preference controls two aspects of the behavior of atom labels. The default preference is to use Automatic Atom Labels.

When Automatic Atom Labels is selected:

• The alignment of atom labels will adjust according to the positions of any bonds attached to the atom label.

For example, a "CH₃" atom label entered at the left end of a horizontal bond would reverse itself to "H₃C".

• Hydrogens will be added to or removed from atom labels as necessary to preserve standard valences when bonds are added or changed.

You can use HotKeys to quickly label atoms. For more information see "Labeling Atoms with HotKeys".

You create and edit caption and atom label text with the Text tool. You set the text format in the Document Settings or Object Settings dialog box.

ChemDraw does not install its own fonts. If a ChemDraw document contains fonts that are not available on a particular computer, they are substituted with available fonts.
