But it's possible with vClone script. Use Orient+History option. http://moi3d.com/forum/index.php?webtag=MOI&msg=7203.11

No. MoI can't embed scripts in 3dm file, but it can store a history data.
Forgot to say, in your particular case you can use rotate command manualy. It will be faster than using vClone. But vClone is much more flexible in most cases.
