Error while opening large ChemDraw .cdx structures in Chem3D:
The number of atoms in this molecule exceeds the atom synchronization limit. The ChemDraw panel cannot load the molecular structure.


By default, the ChemDraw LiveLink mode is available only for molecules of fewer than 200 atoms.
To change the default setting:
1. Go to File>Preferences. The Chem3D Preferences dialog box appears.
2. Click the ChemDraw tab.
3. Specify the number of atoms in Atom Synchronization Limit (100-10000).
4. Click Apply and click OK.

Note: A higher value in the Atom Synchronization Limit (100-10000) field slows down the drawing as large diagrams have to be generated.
