BondSpacing Property

CDXML Name:BondSpacing
CDX Constant Name:kCDXProp_BondSpacing
CDX Constant Value:0x0804
Data Size:INT16
Property of objects:kCDXObj_Document, kCDXObj_Bond
First written/read in:ChemDraw 4.0
Required?Until ChemDraw 4.5

Description:

The spacing between segments of a multiple bond, measured relative to bond length.

In CDX files, this value is stored as (10 * the bond spacing as a percent of length), so 18% of length = 180.

In CDXML files, this value is stored simply as (the bond spacing as a percent of length), so 18% of length = 18.

Note that this property (in combination with kCDXProp_BondLength) is redundant with kCDXProp_BondSpacingAbs. Only one of the two need be present. If both are present and contradictary, ChemDraw gives preference to the BondSpacingAbs value.

If this property is absent:

If present, the kCDXProp_BondSpacingAbs value will be used. If that property is not present, then the value from the same property of a containing object will be used. That is, if this property is omitted from an object, but present for the Document, the Document's value will be used. If no value is found at all, ChemDraw will use the value from its last-used Style Sheet.
