ChemDraw 3.5 (*.chm)

---

ChemDraw 3.5 file formats are used for saving or opening ChemDraw documents using the version 3.5.x of ChemDraw. These documents can also be opened in versions 3.0, 3.0.1, 3.0.2, and 3.1 of ChemDraw as long as atom properties are not used in the files.

NOTE: When you save a ChemDraw file in one of these formats, all features specific to later versions are lost. For example, multi-attached atom labels, variable attachment points, and multicenter bonds are not be saved.
