ISIS/SKC and ISIS/TGF

---

You can save a ChemDraw document in an ISIS file format for export to an ISIS application, or import a file created by an ISIS application into ChemDraw.

ChemDraw Pro provides two ISIS file formats:

• ISIS/Sketch (*.skc) -For saving files as a binary sketch file for transfer to another ISIS application running on the same operating system (this format is used on the Clipboard).
• ISIS/TGF (*.tgf) -For saving as an ASCII text file (a Transportable Graphics File) for transfer to ISIS applications on different platforms.

NOTE: When transferring between ChemDraw and ISIS/Draw, if information in a file or on the Clipboard contains only non-bond, unsupported objects, the information is imported as a WMF (metafile) or PICT graphic. However, if a supported object, such as a bond, is also in the file or on the Clipboard, then only the supported object appears.

NOTE: Object types in ISIS not supported in ChemDraw, such as polymers, are not transferred. Object types in ChemDraw not supported in ISIS are not transferred. However, in some cases, such as different arrow types, the arrow is converted to the most similar form.
