Isometry                                         Switches to isometry mode;

Perspective                                     Switches to perspective mode;

Update rotation center                    Changes the point which the molecule rotates around on scrolling (see Interface notes);

Best view                                       Moves the "camera" to view the molecule better foreshortened;

Center                                            Moves the "camera" to view the molecule at the center of the image, filling 4/5 of its width or height;

Specify the “Camera” position         Opens a window which allows the user to explicitly set the coordinates and orientation of the view “camera”;

Remember the “Camera” position in clipboard Copies the coordinates and orientation of the view “Camera” into clipboard;

Restore the “Camera” position from clipboard Restores the coordinates and orientation of the “Camera” previously saved in clipboard;

Draw export picture                        Renders anti-aliased picture of molecule on the image;

Show axes                                      Displays X, Y, Z axes on the molecule;

Center axes to molecule                  If checked, the XYZ axes will begin at the center of molecule (otherwise, they will begin at the point with (0;0;0) coordinates);

Labels on atoms                             These subitems allow different labels on atoms in displayed molecule to be shown:

Seq. number                                   The atoms are supported with labels identifying their sequence number;

Type                                              The atoms are supported with labels identifying their type (H, C,  Cl, etc);

Type+number                                 The atoms are supported with labels identifying their type and sequence number;

Type+number in group                    The atoms are supported with labels identifying their type and sequence number in groups of the atom type;

Clear labels                                    All labels on atoms are removed;

Show labels on selected atoms only If checked, the labels are shown only on atoms which are selected;

Labels style                                    Changes the default appearance of labels on atoms (size, font, etc).

Structural parameters                      These subitems allow geometrical parameters in current structure to be viewed:

Show all interatomic distances         The distances between all atoms in selected fragment (or the whole molecule, if no atom is selected) are shown on the image. To hide them, right-click on the screen;

Show all bond lengths                     The distances between bonded atoms in the selected fragment or the whole molecule are shown;

Show all bond angles                      All bond angles in the selected fragment or the whole molecule are shown;

Clear                                              Clears all parameters designations;

Style                                               Allows the default appearance of lines and labels which represent structural parameters to be changed.

Show Van-Der-Waals spheres       Transparent spheres with sizes corresponding to standard Van-Der-Waals radii are drawn around all atoms (this feature is limited in the current version);

Release all captions                         If clicked, all captions on atoms will be unlinked to their atoms (this option can be used, for example, to obtain a picture of molecule where each atom has two different labels). This mode allows one to draw such pictures:

Hide certain atoms                          Hides all hydrogen, dummy atoms, etc;  

Toolbars          Displays or hides the toolbars on the main window.
