Tutorials
The tutorials illustrate fundamental drawing techniques. Each tutorial introduces new techniques, or variations of tech-
niques from previous tutorials. We therefore suggest that you follow the tutorials in order.
Before you begin, review "Conventions used in this guide" on page 1 to familiarize yourself with the terminology.
ChemBioDraw 13.0 checks for correct chemical syntax as you draw. If there is an error, a red box appears around the
erroneous object (the red box does not print). To disable the red box on a specific object, right-click the object and
deselect Display Warnings on the context menu.
Tutorial 1: Drawing a structure
In this tutorial, we explain how to draw this structure:
If you want the want the bond angles and lengths to be fixed, go to Object>Fixed Lengths and Fixed Angles. This
ensures that bond lengths and bond angles are consistent throughout the structure.
Note: The fixed length dimension is set in the Drawing tab of the Document Settings dialog box. The fixed angle
dimension increments angles by 15 degrees.
To create bonds:
1. Go to View>Show Main Toolbar.
2. On the Main toolbar, select the Solid Bond tool.
3. Click in the document window. A bond appears.
4. To add a second bond, click the right-end of the bond you just created.
The two bonds form a 120-degree angle.
Note: The chain angle setting determines the angle between the two bonds. To change the chain angle, see "Draw-
ing settings" on page 260.
5. To create a tertiary carbon, click the same place as in step 4.
Changing bond order
To create the double bond, either click and drag over the vertical bond you drew in step 4 or double-click it.
