3D Molecules Editor 1.5

The "3D Molecules Editor" serves as a practical platform for constructing and manipulating three-dimensional molecular models encompassing both organic and inorganic compounds. Its functionalities include support for 3D printing and a dedicated "Test Yourself" mode, which facilitates learners in assessing their understanding of molecular structures. This application is particularly useful for chemistry students at high school and college levels who are exploring concepts related to molecular bonding and orbital interactions through visualisation.

For educators seeking tools that enable students to build molecules with comprehensive 3D visualization, "3D Molecules Editor" presents a competent solution. It allows users to create diverse molecular structures featuring single, double, and triple bonds, as well as cyclic arrangements. The program offers various visualization styles, including stick, ball-and-stick, and space-filling (CPK) models.

The application provides detailed information about molecular components, such as visualising atomic orbitals, electronic effects via arrows, bond lengths, and element symbols. The prominent feature of the full version is the “Test Yourself” mode, designed to evaluate learners’ grasp of chemical structures. Access to this feature requires unlocking the full version from within the app.

Supporting 3D printing, the software enables the export of models as STL files, compatible with most 3D printers. This integration offers an effective means for creating tangible molecular models. To assist new users, a built-in help function offers clear instructions accompanied by screenshots illustrating software operations.

The program supports opening and editing molecules in SDF and PDB formats, sourcing data from repositories such as NCBI's PubChem or the RCSB Protein Data Bank. Once constructed, molecules can be saved or shared via email, facilitating assignment submissions or collaborative learning.

Key features include:

• Exportation of molecules in STL format for 3D printing.
• Construction of organic and inorganic molecules using most periodic table elements.
• Loading, editing, and saving models in SDF and PDB formats.
• Support for single, double, and triple bonds.
• Ability to build cyclic compounds.
• Visualization options including wireframe, stick, ball-and-stick, and space-filling models.
• Display of atomic orbitals and electron effects.
• Access to data on bond lengths and elemental symbols.
• Bond-angle optimisation features.
• Options to save or share models via email.
• Export to VRML format for further applications.
• Direct opening of molecule files from emails and cloud services.

Overall, "3D Molecules Editor" is a valuable resource for introductory chemistry students seeking to deepen their understanding of molecular bonding and orbital theory through three-dimensional visualisation tools. Its capabilities support both learning and practical applications such as 3D printing of molecular models.
