Free organic software for mac

XDrawChem is a two-dimensional molecule drawing program for Unix operating systems.
It is similar in functionality to other molecule drawing programs such as ChemDraw.
It can read and write MDL Molfiles, and read ChemDraw text and binary files, to allow sharing between XDrawChem and other chemistry applications, and it can create images in popular formats like PNG and EPS
Main features:
- Fixed length, fixed angle drawing.
- Automatic alignment of figures. Detects structures, text, and arrows and places them automatically.
- Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in built-in library.
- Can retrieve structures from a network database based on CAS number, formula, or name. The data file (30 Mar 2005, comma-separated) is freely available.
- Can draw symbols such as partial charge, radicals, etc.
- Can read MDL Molfiles, CML [Chemical Markup Language, defined in J. Chem. Inf. Comput. Sci.39(1999), 928-942], ChemDraw(TM) binary format, ChemDraw(TM) XML text format.
- Can write MDL Molfiles, CML, ChemDraw(TM) XML text format.
- Can also read and write any format supported by the current release of OpenBabel.
- Can export pictures in PNG, Windows bitmap (*.bmp), Encapsulated PostScript (EPS), and Scalable Vector Graphics (SVG).
- Can generate 3-D structures with the help of the external program BUILD3D.
- Online help, including tool tips.
- 13C-NMR prediction, based on Bremser W, Mag. Res. Chem.23(4):271-275
- 1H-NMR prediction, based on additive rules and functional group lookup methods, described in Pretsch, Clerc, Seibl, Simon, "Tables of Spectral Data for Structure Determination of Organic Compounds", 2ed., 1989, Springer-Verlag
- Simple IR prediction.
- Simple pKa estimation.
- Octanol-water partition coefficient estimation.
- Reaction analysis: gas-phase enthalpy change estimate, 1H NMR and 13C NMR comparison.
- Integration with OpenBabel, allowing XDrawChem to read and write over 20 different chemical file formats.
Enhancements:
- Worked on bug #1236716 and #1255229, regarding XDrawChems rendering of text typed into the QTextEdit mini text editor.
- Fixed bug #1254917, relating to segfaults when drawing symbols.
- Updated database back-end to use data parsed from the
- PubChem Compounds database, and updated XDrawChem to link to PubChem compound records where available.

As virtual modeling skills become an assumption in the market, students developing their careers need the best, most up-to-date and work-relevant tool to train with. Archicad is now FREE for architectural students worldwide. This is the full, latest version of Archicad - the building design tool youre likely to confront in your first workplace and thereafter.

Archicad 10 is the most powerful ever Virtual Building design software. It gives you more control over your design, while maintaining accuracy and efficiency in documentation. While you raise walls, lay floors, add doors and windows, build stairs and construct roofs this Building Information Modeling tool creates a central database of 3D model data. From this you can extract all the information needed to completely describe your design - complete plans, sections and elevations, architectural and construction details, bills of material, window/door/finish schedules, renderings, animations and virtual reality scenes. That means while youre designing, ArchiCAD is creating all the project documentation so theres little repetitive and tedious drafting work. And unlike designing in 2D software, the Virtual Building approach also means that you can make changes at any time maintaining the integrity of your documents, without risking costly errors or costing you productivity.

And - being open-standards and developed by architects for architects - it integrates with MaxonForm for you visionary organic models, and SketchUp for your simple conceptual 3D drawings.

Best the best - but get prepared - download Archicad for FREE!!!

Archicad 10 Student Edition Germany 10 brings an enhanced program which can help architectural students to develop their concepts, and prepare for their virtual modeling career. Its interactive training guide supports their move into virtual building design. ArchiCAD helps users analyze their designs earlier: assess the spatial properties and design impact in 3D, generate accurate documentation rapidly and efficiently coordinate projects both internally and externally.

ArchiCAD's open platform allows integration with environmental, organic modeling and structural applications to further enhance and refine the architectural design to meet client and authority standards.

Requirements:

• Mac OS X
• 1Gb RAM
