Attachment Points

---

The ability to indicate an attachment point is useful in polymer-bound combinatorial synthesis, protein chemistry, and other situations. ChemDraw has four standard attachment point drawing tools that allow you to indicate a point of attachment while maintaining chemical meaning.

The bead tool is specifically intended to indicate attachment to a resin, but the tools are interchangeable. Any if these tools may be used for variable attachments in queries (see "Using Variable Attachment Positions"), but only the diamond tool will show rank numbers. That is, if you add more than one diamond to a structure, the points will automatically number sequentially.
