Property of objects:kCDXObj_Node
First written/read in:ChemDraw 8.0
Required?No

Description:

Type of external connection, for atoms of type kCDXNodeType_ExternalConnectionPoint.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
0 Unspecified Nothing is specified about the node's isotopic abundance
1 Diamond The attachment point is indicated by a black diamond at the end of a bond
2 Star The attachment point is indicated by an asterisk at the end of a bond
3 PolymerBead The attachment point is indicated by large shaded sphere at the end of a bond
4 Wavy The attachment point is indicated by a wavy line perpendicular to the end of a bond

If this property is absent:

The node is treated as having Unspecified external connection type, which is then treated as a black diamond by ChemDraw.
