Chemical drawing programs review. Dr Tamas E. 2. 01. If you have any comment, do not hesitate to contact the author at the above address. Introduction. The immense development of microelectronics has banished the use of a typing machine, drawing pen, Indian ink and templates.
Instead, text editors like MS Word, Corel Word. Perfect or Apache Open. Office, etc. With the aid of these one can create professional looking articles and drawings, and a large amount of time for the rewriting, redrawing and making corrections can be spared as well.

The creation of chemical structures with the conventional drawing software applications would be extremely painstaking and practically impossible. With publication in mind aesthetics and quality come to the front, ensured by built- in templates, bonds constrained to fixed length and angles, etc. Direct 3. D editing is usually not possible – 3.

D features of a molecule can be visualised only by using the wedged/hashed bond drawing methodology. The availability of different tools (palette of fonts, arrows, lines and curves, arcs and other shapes or graphic primitives) is also of high importance. If precise 3. D representation of the molecule is needed, its import from a modelling program or 3. D data base is the most feasible arrangement, although the recent drawing packages usually contain a simple 2.

D . Nowadays an obvious requirement is WYSIWYG (What You See Is What You Get). Under the Windows OS most tasks (printing, screen and printer fonts, resolution or any other system wide parameter) are maintained by Windows itself and its set- up is the determining factor. Another important point is the user- friendliness of the program. This means that the user interface of the program, which ensures the interactive two- way communication between the user and the machine, should be simple but effective. The information sharing with other programs, database applications must also be many- sided.
The distinction between and ranking of the lead applications is not so straightforward anymore: while in the first version of this review (1. Chem. Window, Chem. Draw and Isis/Draw) and there were considerable differences between them, the drawing modules of the recent programs are side by side.
Accelrys Draw is the incarnation of the old ISIS/Draw with a brand new and more user- friendly interface. However, in a few tools ISIS/Draw compatible mode can be activated. A few new features (concerning mainly database use) have been added, a few drawing tools have been refined while a few other ones are not supported anymore. It is an alternative input modul to its own and the Reaxys databases as well. The drawing of biological objects have been developed lately as well as integration with databases (with Scifinder recently). Available as Windows or Mac version.
Version 1. 3 has more bugs than its predecessors, version 1. The Chem. Bio. Draw for i. Pad is a considerably simplified version intended for basic molecular editing. Chem. Sketch is the input modul of Chem.
Folder and several other applications of the ACD suite. It has several modules, extensions, and add- ins concerning the calculation of physical- chemical properties, import, processing and databasing of spectra and chromatograms, naming of molecules, prediction of NMR spectra, etc. Available as Windows or as an older Linux version. It has everything necessary for creating publication quality chemical documents. It is integrated with Chem. Doodle Web Components and Chem.
Doodle Mobile (i. OS and Android phones).
Its architecture is somewhat different from those of the old- timers, it has a handful of very useful brand new tools, a few new question- of- taste ones and some less impeccable features as well. In addition to structure and document editing features it contains several tools (some of them called . The main drawback of the previous versions that round- trip editing was a bit cumbersome in the Windows has been resolved. The Draw. It modules of the Chem. Window and Academic editions are the same.
There are no relevant news for the time being. The commercial version of Chemistry 4- D Draw is integrated with its Chem. D database and nomenclature modules (depending on the purchased version). Available as Windows or Mac version. This is an interesting and very dynamically developing Java- based multiplatform chemical editor for drawing structures, reactions and queries with excellent features for web applications.
