Can I share a Chem3D molecule via email?
Yes, while you have a molecule rendered on the screen, tap on the Share icon in the top toolbar and then tap on the email icon. This will attach the molecule file to the email. (Note: you must have an email setup). The molecule will be shared in C3XML format.
If you receive a C3XML file as an email attachment, tap on it. You will be invited to open the file in a number of apps, including Chem3D. Tap the Chem3D icon, and the file will open in the Chem3D app.
