C3D File - opening and understanding
Did your computer fail to open a C3D file? We explain what they are used for and recommend software that we know can open or otherwise handle your .C3D files.
What is a C3D file?
A .C3D file is a Chem3D Format file. These C3D files contain molecular visualizations created in Chem3D, a software created for chemists. This software is divided into three sections. These sections are two-dimensional chemical drawings, three-dimensional molecular modeling, and chemical information management. You have access to pre-generated molecular structures that can be found in the comprehensive internal sub-structure library.
