original FlatMol is no longer being sold or supported
Flatmol 2 is now available ! find it on the app store here
entirely new re-write
simpler, with a better user interface
$ 4.99 for the full version
a complete re-write, ** NOTE: original flatMol files are not compatible **
Free Lite Version coming soon (w/ limited saves)
Version 7.2 : September 16, 2014
Improved User Interface
* Automatic molecule selection
* fewer keystrokes required for Atom & Bond changes in expert mode
Simpler Help Window; the "test canvas" has been removed
Rebuilt for Cocoa
Save Dialog now works properly
Bug Fix: atom overlap no longer causes the application to freeze
Instead, major overlap is detected and not allowed.
Also, some re-wording has been done:
"Sp3 Carbon" is now called "Carbon (4 bonds)"
"Sp2 Carbon" is now called "Carbon (3 bonds)"
"Sp Carbon" is now called "Carbon (2 bonds)"
Version 6.1 released Dec 5, 2013
Re-arrangement of main screen buttons for clarity
Revised user interface for expert mode: atom and bond selection
Revised draw screen interface for clarity
Molecule selection is now smooth
Molecule names are now stored independent from file names
several bug fixes
Version 6.0 released Nov 15, 2011
new Bond Options; Aromatic, Hydrogen and Out of Plane bonding in expert mode.
new Hydrogen Options: add regular hydrogen atoms for emphasis in addition to the original small "fill in" hydrogens.
More Bond Options:
1. - Aromatic (double lines: one solid, one grey)
2. - Hydrogen Bonding ( or strong interactions: grey )
3. - Out of Plane Single Bonds
above the plane as a white triangle;
below the plane as a grey triangle.
Add Hydrogen as a regular type atom for emphasis and enhanced features:
- As large as other atoms, with similar features (such as deletion or element change)
- Available from the periodic chart element selection
- Expert bonding modes apply (such as above and below the plane).
- Note: these hydrogen atoms are not hidden in "line drawing" mode.
Appropriate coordination default values for elements chosen from the periodic table are now automatic.
It remains up to the user to make changes if needed.
Version 5.9.1
more View Options; new Save Canvas Option;
Better Canvas Drawing interface, better Arrows.
View atoms with or without enclosing circles. (Atomic Radii on or off)
Save certain View Preferences (as defaults for the next run)
- H text on/off
- H text font size
- Atomic Radii on/off
Save (and Open) Molecules, Lines, Curves, and Text Symbols as a complete canvas.
More intuitive; Fewer keystrokes to get the job done.
"Sticky" commands; Selection choices no longer re-set with every decision.
(for example; move one selection, and then any other of the same type)
Version 5.8.2
New Drawing Components: Curves and Arrows for curves and solid lines.
Coordination of zero now allowed to depict ions or atoms.
Now you may change the Bond Type within a ring (choose Single, Double, or Triple)
( This fixes a problem that could cause a crash.)
H (as an atom) , H-H (hydrogen molecule), H-, H+ (ions) may be placed as Text in the Draw Screen.
Version 5.6.8
⌥ ⌘ M to show Main Periodic Chart
⌥ ⌘ R to show Representative Elements Periodic Chart
⌥ ⌘ T to show Transition Elements Periodic Chart
⌥ ⌘ I to show Inner Transition Elements Periodic Chart
⌥ ⌘ C to close all Periodic Charts
Text symbols are drawn to the screen at larger size
Molecule perimeter box is hidden during drawing to better show true canvas
(molecule perimeter is used for editing/selection and is not printed)
Version 5.6.5 released Jun 8, 2011
