|CDX Constant Name:||kCDXProp_Atom_ExternalConnectionType|
|CDX Constant Value:||0x0440|
|Property of objects:||kCDXObj_Node|
|First written/read in:||ChemDraw 8.0|
Type of external connection, for atoms of type kCDXNodeType_ExternalConnectionPoint.
This is an enumerated property. Acceptible values are shown in the following list:
|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.
