To set the order of the attachment points, use the Attachment Point tool to click the ends of the bonds in the order you
want.
To change attachment point order:
Click the attachment points with the Attachment Point tool.

2. In the Preferences dialog box, click Building/Display.
3. Deselect Show Attachment Rank Indicators.
