Chem3D: Error while opening large ChemDraw .cdx structures in Chem3D

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. 
 

Solution:

By default, the ChemDraw LiveLink mode is available only for molecules of fewer than 200 atoms.
To change the default setting:
1. Go to FilePreferences. 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.
