2.3.1     Changing File Associations

If you have not selected all formats, the default file association can be viewed or changed at any time by going to the File menu and selecting File Association.  If you have selected all formats, then you receive a message, “all supported file types are already associated with the current application.”  In this case, to change the file associations, you can do it through Windows Explorer.

1.    Open Windows Explorer, and select a file with the extension for which you want to create the association.

2.    Hold down the SHIFT key and right-click on the file.  From the pop-up menu, select Open With...

3.    Set the application that should be used to open the file and select the Always use this program… check box.

4.    Click OK and close Windows Explorer.

2.4     Changing Default Directories

If you are running a single-user (stand-alone) copy of 3D, the default directory settings are likely fine.  If you have a network copy, it is advisable to change the default directory settings in the ACD/Labs software so that the default drive for saving work-in-progress is the user’s local hard drive, not the remote server.  After creating local access for either limited or unlimited numbers of seats, then at each local installation:

1.    In the ChemSketch window, from the Options menu, choose the Preferences command.

2.    Click on the General tab.  And in the Default box at the bottom of the tab specify the directory that will be opened every time you open the Import, Open, Save, Export dialog boxes in the ChemSketch window:

Note       In the Private box you can set the directory for recording the configuration of ChemSketch program (e.g., template.cfg and qrstyles.stl files).

3.    Click OK.

4.    Switch to 3D Window and from the Options menu choose the Set Default Folder… command and find the required folder.  Click OK.

2.5     Exiting ACD/3D Viewer

You can exit from the program in any of the following ways:

·       click  in the upper right-hand corner of the title bar of any window;

- OR -

·       from the ACD/Labs menu choose the Close All command.  This will attempt to close all ACD programs that are currently open, one right after the next.

- OR -

·       select the Exit command from the File menu.  This will close only the currently open ACD program.

You will be prompted to save your work in the appropriate file formats, depending on the window that you are exiting.


 

3.1     Objectives

In this chapter you will learn how to:

·       insert molecule into the 3D Window;

·       customize the view of molecules (color, atoms’ radii);

·       save and load view settings; and

·       measure distance between atoms and calculate angle between bonds.

3.2     Inserting a Molecule into the 3D Window

1.    Start up ACD/3D Viewer as described above.

2.    Click the ChemSketch button  on the Window Switching bar at the bottom of the window.

3.    This will switch you into the ChemSketch window.  Click the Dictionary button  in the upper right part of the ChemSketch window (circled in blue below):

Note       The free ChemSketch version doesn’t include the Dictionary module.  This module is a commercial one, so if you have a free ChemSketch in use, draw any desired structure by using the ChemSketch interface tools.  (For details upon drawing structures refer to the ACD/ChemSketch User’s Guide.)
