1.    Choose the Radii… command from the Options menu to open the Atomic Radii dialog box containing default settings for atom radii of various elements:

2.    To view the currently set radius of any element click on it in the list.  In the right column the corresponding value is highlighted.

3.    To change the atom radius for an element, double-click on it in the list and type the new value, e.g., 1.5, in the Change Radius box that appears:

4.    Click OK to save changes.

Note       The atomic radius is expressed in relative units.

5.    As soon as the changes are made to the Atomic Radii dialog box click OK.

Note       Next time you start ACD/3D Viewer, the default values will be reset to their previous values.  For more details on how to save and load default settings refer to Section 3.4.

6.    To see the full result of changing the atomic radii, switch to the Spacefill view  to obtain the following view:

3.3.3     Changing Display of Atom Radius

1.    Switch to the Balls and Sticks view mode .

2.    Click the Increase Atoms’ Radii by 5% button .  Each additional click on this button increases the radii of all displayed atoms by 5%.

3.    Click the Decrease Atoms’ Radii by 5% button  to decrease the radii of all displayed atoms by 5%.

Important     These tools do not affect the actual radii of atoms (those specified in the Atoms’ Radii dialog box), but only change the display.

3.4     Saving and Loading View Settings

You can save settings that you have specified during the current work session as a *.3ds file, load them from a previously saved file and set them as the new default.

3.4.1     Saving View Settings

1.    Choose the Save Settings… command from the Options menu to display the following dialog box.

2.    Select the check boxes of the attributes that you want to be saved.  Note that selecting the Radii check box will allow you to save settings specified in the Atomic Radii dialog box, but not the current radius display options (see Section 3.3.2 and 3.3.3).

3.    Click OK and in the dialog box that appears specify the name of the file and location (drive and directory).  Note that the file should be saved with *.3ds extension.

4.    Click OK to save the file.

3.4.2     Loading View Settings

If you have previously saved view settings, you may load them for the current session.

1.    Choose the Load Settings… command from the Options menu to open the Load Settings dialog box.

2.    Find the *.3ds file you want to load.

3.    Click OK.  The settings contained in this file will be loaded for the current working session.

3.4.3     Setting Default View Settings

If you want to use specific settings each time you work with ACD/3D Viewer, you should set them as default ones.

1.    Specify required view settings (refer to Section 3.3).

2.    Save them into a file using the Save Settings… command (Options menu).

3.    From the Options menu choose the Set Default Settings… command to open the Set Default Settings…dialog box.

4.    Find the file with the setting you want to set as default.

5.    Click OK.  From this point on, each time you open ACD/3D Viewer these settings will be loaded until you specify other ones.
