(-vp)VIEWDIRECTION DOEN'T WORK.

Hi all,

when I use the command -viewdirection- which I want to Rotate the view according to the UCS.

Please see the log below:

I rotate the UCS,

and input (-vp), then choose "v", I input 90(no matter I input 90/180/270/45).

nothing happen. 

 

Could you please tell me how to rotate the view?

Thanks

Best regards
