How can I limit the amount of memory used up by Chem3D?

Take the following steps to reduce memory usage:

1. Reduce the number of open model or table windows.
2. Reduce the size of model windows.
3. Avoid displaying Space Filling models while building.
4. Do not record movie frames while doing minimizations or rotations.
5. If your model has more than one movie frame, use Edit/Clear Frames/Clear All Other Frames to eliminate unneeded frames.
6. If you have performed calculations, use Edit/Clear Calculations to eliminate unneeded calculations.
7. If you have created surfaces, use Edit/Clear Molecular Surfaces to eliminate unneeded surfaces.
8. In Movie Settings, reduce Smoothness (move the slider to the right) to decrease the number of frames saved while rotating.
9. Close Messages and Measurements windows when you no longer need them.
10. Close the Table Editor instead of leaving it in the background or minimized on the desktop.
