By default, PyMOL creates single bonds when joining fragments. To change a bond valence, CTRL-right click on the bond to select it. You should see a "ring" about the bond. Then press CTRL-W to cycle through the possible bond valences: single, double, triple.
Note that it is essentially impossible right now to build complex molecules in PyMOL without using some external molecular minimization and mechanics program, since the "molecular sculpting" feature can only maintain pre-existing atomic geometries. For coarse modeling of protein-ligand interactions, I tend to use PyMOL to draw the initial covalent structures, use MacroModel to perform energy minimization, and then return the structure to PyMOL for purposes modeling the complex. - Warren -- mailto:war...@sunesis.com Warren L.
