ChemDraw (*.cdx)

---

The ChemDraw file format is the native format for ChemDraw version 4.0 and later. This is a public tagged file format that stores information about a ChemDraw structure in a series of data blocks. This format is designed to be easily generated and interpreted by other programs. This format accurately stores anything that can be drawn in ChemDraw.

NOTE: Imported drawings saved within a ChemDraw file created using ChemDraw for Macintosh are lost when the file is opened using ChemDraw for Windows. The same applies for objects saved in ChemDraw for Windows and opened on a Macintosh. However, all ChemDraw specific information is preserved.
Imported drawings include any graphics pasted into a ChemDraw document from another Macintosh application. They also include Chem3D drawings imported using the Insert Object dialog box or the "Get 3D Model" Edit menu command in ChemDraw for Windows.
