Attach Rings with Pipette Sketcher

Last Updated: Oct 10, 2015 04:50PM PDT

Summary: Sometimes you need to join a ring to two or more existing bonds in a structure. Pipette Sketcher provides two simple ways to accomplish this task. This article explains how.

Example 1: Multi-Selecting Bonds

  1. Starting with the following structure:

  2. Select the two bonds for attaching the new ring. This is achieved by one of the following methods:
Device Description
Non-touch Hold the CTRL key when clicking on the bonds.
Touch Tap the atoms or bonds together or in quick succession.

Tip: If the ring you form is too large or small, the size can be quickly adjusted using the Insert Atom or Remove Atom tools.

Note: While the second example is more complex than the first one, it allows greater control over complex cyclic compounds.
