Sure, you can interactively rotate bonds. If you Ctrl-doubleclick a bond it should show a little menu where one of the choices is to rotate that bond. After you activate the rotation, the "adjust torsions" dialog will appear, which includes various ways to rotate the bond. You can have several rotatable bonds at the same time.
Here is more about Adjust Torsions:
Also, the tutorial "Structure Comparison and Analysis" includes measuring distances, finding H-bonds and clashes, and rotating bonds:
I hope this helps,
