Instructions for exporting structures for 3D viewing are given on the RasMol page see "Method 2" there. You can use it to draw chemical structures, and export them for viewing as 3D models. This is an introduction to ISIS/Draw, a program from MDL that is free for non-commercial use. The time needed to draw this complex structure, using the features described below, was less than two minutes. Unusual atoms labels (X for halogen, Me, etc) Bottom of page return links and contact information Additional useful features in ISIS/DrawĨ. Multiple bonds, Heteroatoms, Displaying hydrogen atomsį. Original version of this Guide by Greg Pearceĭ. Import and export structure files in a variety of standard file formats.> Writing, drawing and viewing chemical formulas.Produce an optimized 3D model of your 2D structure.Generate all possible structures for a given Markush representation.Generate suggested tautomeric forms of your drawn structure.Search the Dictionary of >170,000 systematic, trivial, and trade names.Generate structures from InChI or SMILES strings, or copy/paste from ChemDraw.Use graphical templates to insert objects including molecular orbitals, Lewis structures, Newman projections, laboratory equipment, and more.Insert pre-drawn templates of amino acids, aromatics, carbohydrates, steroids, sugars, and more.Associate atoms in reactant to product schemes with atom-atom mapping.Label reaction arrows with specific experimental conditions.Easily draw reactions and complex chemical schema (including biotransformation maps).Edit structures to customize the chemical bond type, stereo configuration, atom type and charge, radical label, atom numbering, and more.Draw molecular structures such as organic molecules, organometallics, biomolecules, polymers, 2D and 3D structure representations, delocalized Markush structures, peptide sequences.
