Drawing a Ring

---

If Fixed Lengths is on when you draw a ring, the length of each bond in the ring is automatically set to the fixed length. If Fixed Angles is on, the angle the first bond in the ring makes with the X-axis is restricted to 15-degree increments. For more information, see "Drawing Constrained Bonds".

To draw a ring:

1. Click a ring tool.

2. Position the pointer in a document window.

The cyclohexane tool is shown below:

3. Drag from the beginning to the end of the first bond.

When you point in a document window, the pointer changes to a ring tool pointer. The highlight box on the ring tool pointer indicates the atom that is drawn first. The bond directly below the highlight box is the bond that is drawn first.
