| CDX Constant Value: | 0x0A02 |

Description:
The type of arrow object, which represents line, arrow, arc, rectangle, or orbital.
In CDX files produced by ChemDraw 8.0, this property was mistakenly written as a 1-byte INT8 value. When reading CDX files, if the size of this property is found to be 1 byte instead of the expected 2 bytes, the actual value should be interpreted as actualType = (INT16)savedType. CDX format interpreters that follow the best practices for reading integer values from CDX files will handle this error automatically. ChemDraw returned to writing INT16 values starting with version 8.0.6.
This is an enumerated property. Acceptible values are shown in the following list:
| Value | CDXML Name | Description |
| 0 | NoHead | NoHead |
| 1 | HalfHead | HalfHead |
| 2 | FullHead | FullHead |
| 4 | Resonance | Resonance |
| 8 | Equilibrium | Equilibrium |
| 16 | Hollow | Hollow |
| 32 | RetroSynthetic | RetroSynthetic |
| 64 | NoGo | Failed reaction (crossed-out arrow); may be combined with other types |
| 128 | Dipole | Dipole |
If this property is absent:
The arrow is treated as headless.
