CoolChemsketch 2nd version

ChemSketch is designed to be used on its own for drawing chemical structures, reactions, schematic diagrams or integrated with other ACD applications and as the front end to our software. Able to import Windows Metafile, MDL MOL, CS ChemDraw, or ISIS/Sketch BIN file. Export Bitmap, TIFF, Metafile, MOL, Paintbrush, ISIS/Sketch, GIF , and ChemDraw. Fully loaded with useful pre-drawn structures including lab equipment, DNA/RNA building kit, amino acids etc. Structures can be 2D "cleaned" as well as 3D optimized using ACD's powerful algorithm. Publish a professional quality report from within ChemSketch or drag drop structures/text into MS applications i.e. MS Word.
Both ChemSketch and ChemBasic are available for free at http://www.acdlabs.com/download/
The ChemBasic language, which is integrated with ACD/ChemSketch chemistry drawing software, is intended to be a tool for

manipulating chemical structures, both 2D- and 3D;
customizing ACD/Labs software, through direct access to its embedded functionality;
developing add-ons to ACD/Labs chemistry software.

The ChemBasic language itself is a mixture of good old BASIC with thoroughly integrated chemistry and drawing objects (e.g., Assembly, Conformation, Molecule, Structure, ...). For more information, visit http://www.acdlabs.com/chembasic/
