a molecule drawing tool for the educator or student

Simple and flat, chemical structures made with this program are designed to be compatible with a paper surface rather than to compete with 3D models.


Help Topics are accessible from the Menu
Undo is available (command Z) ["Edit" Menu]
Viewing styles may be changed ["View" Menu]
Molecules may be Rotated ["Edit" Menu]
Any atom may be drawn and then changed to an different element.

* Novice and Expert Modes
* Quickly fill all open valencies with Hydrogen atoms
* Quickly draw predefined three to six membered aliphatic rings plus benzene
* Fuse rings for the above ring types
* Remove an atom from a molecule (except from within rings)
* Number atoms sequentially
* See more features in the supporting web page.

Once complete, flatMol molecules may be saved for future editing, printed, saved as a .mol file (which can be read into 3D rendering programs), or saved as a pict. file.
Once saved as a pict. file, they may be dropped into a word processor or test program or converted (via other apps) to different formats if needed,

This program is designed to keep things simple; complicated ring structures or structures involving unusual bonds may not be able to be drawn here at all. I have chosen to disallow features such as unusual bonding or removal of random atoms within a ring group to keep other features ( such as rotation ) working properly.

What's New in Version 7.2

Improved User Interface

* Automatic molecule selection
* fewer keystrokes required for Atom and Bond changes

Simpler Help Window; “test canvas” removed

Rebuilt for Cocoa
Save Dialog now works properly

Bug fix : atom overlap no longer causes the application to freeze
(overlap is detected and not allowed)
