C3D2 files are data files used by Chem3D, a chemical modelling and molecular visualisation program for Microsoft Windows.
They store input and output data for the Cartesian 2 chemical modeller. The data is intended to be read and processed by Chem3D rather than used as a general-purpose document format.
Open the C3D2 file in Chem3D on Microsoft Windows. Use Chem3D's Open command and select the file if it is not shown by the default file filter.
Open the C3D2 file in Chem3D and use the program's Save As or export function to create a format supported by the required application.
Conversion is dependent on Chem3D being able to read the file and on the chemical and modeller data being supported by the selected output format.
