Key Features:

• Generate 0D (clusters, nanoparticles), 1D (nanowires, nanotubes), 2D (nanosheets, thin films), and bulk crystals.
• Automated builders for nanoclusters, nanotubes, and supercells.
• Geometric operations: rotation, translation, scaling, merging, slicing, and symmetry analysis.
• Supports formats: .cif, .xyz, .pdb, .vasp, .json, etc.
• Integration with ASE and Pymatgen via built-in converters.

---

🎨 GAMVis
