Hi,

I am following a video tutorial (not from here) and the instructor at one point does a mirror to a subd object and then attaches the two parts afterwards. He does this by simply selecting the subd object and going to the subd tab and selecting mirror and the X axis.
I follow this exactly, but my mirror goes downward and rotated on the Y axis. I cannot figure this out. I have deleted history and done what the Maya help says which is to freeze transformations and then do this, but I get the same result.
I have managed to get my desired results by going to poly mode and mirroring geometry with combine on the -Y.

I am wondering what my problem is and why I cannot mirror in the subD mode as shown in the video.
Please explain why if possible. Thanks.
