WinDrawChem is a freeware two-dimensional Molecule drawing program for Windows 95/98/NT/2000/XP. It is Similar in functionality to other molecule drawing programs such as ChemDraw (TM, CambridgeSoft). It can read and write MDL Molfiles to allow sharing Between XDrawChem and other chemistry applications, as well as read ChemDraw binary and text files.
Features include:
100% compatible UNIX/Linux/FreeBSD version
Fixed length, fixed angle drawing.
Automatic alignment of figures. Detects structures, text, and arrows and places them automatically.
Can read and write MDL Molfiles, and can export drawings as pictures.
Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in built-in library.
Can draw symbols such as partial charge, radicals, etc.
Online help, including tool tips.
Support for CML (Chemical Markup Language) as defined in J. Chem. Inf. Comput. Sci.39(1999), 928-942
Support for reading ChemDraw (TM, CambridgeSoft) XML (text) and binary files.
Can export Encapsulated PostScript (EPS) files which can be imported into other applications.
