However there are a number of molecules in which 2 substituents only differ in their conformations. In these cases when I click 'Add hydrogen and Build model', Hyperchem will swap the position of the two substituents. Has anybody gotten around this problem? Are there any other drawing programs which can allow me to draw conformations properly?
