• Right-click at any level, point to Visibility and
click Hide... (Atom Group, etc.).
Hidden atoms or groups are displayed in
parentheses in the tree control.
By default, all levels in the hierarchy are set to
inherit the settings of the level above, but you can
reset the default to hide a group but show individual
atoms in it. To show an atom belonging to a hidden
group:
• Right-click on the atom in the tree control,
point to Visibility and choose Show.
Showing Hs and Lps
To show all hydrogen atoms and lone pairs in the
model:
• From the Model Display submenu of the View
menu, choose Show H's and Lp's.
A check mark appears beside the command,
indicating that it has been selected.
When Show Hs and Lps is not selected, hydrogen
atoms and lone pairs are automatically hidden.
Showing All Atoms
If you are working with a large model, it may be
difficult to keep track of everything you have
hidden. To show all atoms or groups that are
hidden:
3. Right-click again, point to Show... and choose
Inherit Setting.
Moving Atoms or
Models
Use the Move Objects tool to move atoms and
other objects to different locations. If the atom,
group of atoms, bond, or group of bonds that you
want to move are already selected, then all of the
selected atoms move. Using the Move Objects tool
changes the view relative to the model coordinates.
The following examples use the visualization axes
to demonstrate the difference between different
types of moving. To move an atom to a different
location on the X-Y plane:
1. Click both the Model Axis and View Axis tools
to visualize the axes.
NOTE: The axes will only appear if there is a model
in the window.
2. Drag with the single bond tool to create a
model of ethane.
3. Point to an atom using the Move Objects Tool.
4. Drag the atom to a new location.
1. Select a level in the tree control above the
hidden atoms or groups, or Shift+click to
select the entire model.
2. From the Right-click menu point to Select and
click Select All Children.
