What’s New in
Chem3D 9.0
Chem3D 9.0 is enhanced by the following features:
• Redesigned GUI—User customizable, with
new toolbars, new layout for tables and
subviews, new menus and dialogs. The GUI
has been redesigned from the ground up to
make it more usable.
• New Model Hierarchy Tree Control—Lets
you open and close fragments, chains, or
groups; change display properties at different
levels. See “Working With the Model Explorer”
on page 111.
• ChemDraw panel—Building small molecules
is easier than ever. See “Building with the
ChemDraw Panel” on page 74.
• New menu organization—Important
functions are easier to locate.
• Full screen mode—Use Chem3D for demos
or instruction.
• New Dihedral Driver—Do conformation
analysis with graphical display of results. See
“Tutorial 5: Mapping Conformations with the
Dihedral Driver” on page 42.
• Improved support for small molecule
overlays—compare different conformations
or different structures. See “Tutorial 6:
Overlaying Models” on page 43.
• XML table editor—easier to use, better
integration.
What’s New in Chem3D
9.0.1
• View translation tool—translate (pan) the
view without changing the model coordinates.
See “Moving Models with the Translate Tool”
on page 96.
• Safer viewing—new “pure selection tool”
prevents unintentionally moving or rotating
parts of the model while selecting. See “The
Building Toolbar” on page 20.
• Global keyboard modifiers—advanced users
can perform any action while in any mode
using a global keyboard modifier. See
“Keyboard Modifiers” on page 235.
• Improved Zoom control—zoom to center of
screen, center of selection, or center of
rotation. See “Zoom and Translate” on page
235.
• Display axes—display or hide axes centered at
the origin of the model, or at the origin of the
view focus.
• Middle mouse button and scroll wheel
support—use scroll wheel to zoom, middle
mouse button to rotate or translate. See entries
under “Rotation” and “Zoom and Translate”
on page 235.
• New tools for large models:
• View focus—selects a subset of the model
for viewing and manipulation. See “View
Focus” on page 85.
• Select higher group—double click a
selection to select the next higher group. See
“Selecting a Group or Fragment” on page
93.
• Radial Selection—select atoms or groups
within a specified radius. See “Selecting
Atoms or Groups by Distance” on page 94.
