Polymer_FlipType Property

CDXML Name:PolymerFlipType
CDX Constant Name:kCDXProp_Polymer_FlipType
CDX Constant Value:0x0A26
Data Size:INT8
Property of objects:kCDXObj_Graphic, kCDXObj_BracketedGroup
First written/read in:ChemDraw 7.0
Required?No

Description:

The flip state of objects contained within the bracket.

For ladder-type polymers (those polymers with two connecting bonds on each side), there is a potential ambiguity in the order of the connections. The Flip Type property is designed to resolve that ambiguity. This property is appropriate only for brackets with exactly two crossing bonds.

Although this property is written to both Graphic objects and to Bracketed Groups, as of ChemDraw 7.0 it is read only from Graphic objects.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
0 Unspecified Unspecified flip type
1 NoFlip The orientation of the repeating unit does not change between adjacent units
2 Flip The orientation of the repeating unit does change between adjacent units

If this property is absent:

The flip type is treated as Unspecified.
