View Mode

View Mode is where you open a structure and look at it. Load a file, paste coordinates, type an identifier, or search PubChem / ChEMBL — the result lands in the 3D viewport where you can rotate it, inspect it, and take measurements.

What to Do Here​

  • Load a structure from a file, pasted text, an identifier, or PubChem / ChEMBL search
  • Load Gaussian cube data for HOMO, LUMO, electron density, and ESP surface views
  • Rotate, pan, and zoom the 3D view
  • Measure distances, angles, and dihedral angles by clicking atoms
  • Toggle hydrogens, stereochemistry labels, conformer overlays, volumetric surfaces, and other display options
  • Step through trajectories and optimization histories
  • Export geometries, save images, or generate share links

Typical Flow​

  1. Load a structure with paste, upload, or the Identifier tab.
  2. In the Identifier tab, either paste a SMILES string directly or search by common name, InChI, InChIKey, PubChem CID, or ChEMBL ID.
  3. Check the geometry or surface view — rotate to see it from different angles, show hydrogens if needed, and turn on any available cube layers.
  4. Measure a distance or angle by selecting atoms directly in the viewport.
  5. When you're ready to edit, switch to Build Mode. When you're ready to run a calculation, switch to Run Mode.

Cross-Mode Continuity​

The structure follows you across modes. Whatever is loaded in View Mode is immediately available in Build Mode and Run Mode — and calculation results come back into View Mode as trajectories you can step through.

Good starting point

If you are not sure which mode you need, start in View Mode. It is the fastest place to confirm that the structure looks right before doing anything else.
