MiniCAD. VectorWorks is the easiest, most cost-effective way to design. It has everything you need for precision 2D drafting, powerful 3D modeling and sophisticated client presentations. Plus, it has a built-in Database and Spreadsheet to track costs and materials, and flexible scripting language to automate routine drafting tasks. Best of all VectorWorks is priced within the means of even the smallest design firm.

Swiss PDB Viewer is a free program to display, analyze and manipulate PDB protein structures. Next to features such as protein superimposition, H-bond detection, amino acid mutation etc., the protein is tightly linked to Swiss- Model, an automated homology modeling server running at the Geneva Biomedical Research Center. This allows for threading a protein primary sequence to a 3D template and analyzing homology. The displaying options of the program include spacefill, ball & stick, stick and ribbon representations, all of which can be applied simultaneously within one structure model.
